Its call-note, chip! chip! from which several of its popular names are derived, is altogether different from the trill which must do duty as a song to express love, contentment, everything that so amiable a little nature might feel impelled to voice.

But with all its virtues, the chippy shows lamentable weakness of character in allowing its grown children to impose upon it, as it certainly does. In every group of these birds throughout the summer we can see young ones (which we may know by the black line-stripes on their breasts) hopping around after their parents, that are often no larger or more able-bodied than they, and teasing to be fed; drooping their wings to excite pity for a helplessness that they do not possess when the weary little mother hops away from them, and still persistently chirping for food until she weakly relents, returns to them, picks a seed from the ground and thrusts it down the bill of the sauciest teaser in the group. With two such broods in a season the chestnut feathers on the father's jaunty head might well turn gray.

Unlike most of the sparrows, the little chippy frequents high trees, where its nest is built quite as often as in the low bushes of the garden. The horse-hair, which always lines the grass" up that holds its greenish-blue, speckled eggs, is alone responsible for the name hair-bird, and not the chippy's hair-like trill, as some suppose.

ENGLISH SPARROW (Passer domesticus) Finch family

Called also: HOUSE SPARROW [AOU 1998]

Length — 6.33 inches. Male — Ashy above, with black and chestnut stripes on back and shoulders. Wings have chestnut and white bar, bordered by faint black line. Gray crown, bordered from the eye backward and on the nape by chestnut. Middle of throat and breast black. Underneath grayish white. Female — Paler; wing-bars indistinct, and without the black marking on throat and breast. Range — Around the world. Introduced and naturalized in America, Australia, New Zealand. Migrations — Constant resident.

"Of course, no self-respecting ornithologist will condescend to enlarge his list by counting in the English sparrow — too pestiferous to mention," writes Mr. H. E. Parkhurst, and yet of all bird neighbors is any one more within the scope of this book than the audacious little gamin that delights in the companion ship of humans even in their most noisy city thoroughfares?

In a bulletin issued by the Department of Agriculture it is shown that the progeny of a single pair of these sparrows might amount to 275,716,983,698 in ten years! Inasmuch as many pairs were liberated in the streets of Brooklyn, New York, in 1851, when the first importation was made, the day is evidently not far off when these birds, by no means meek, "shall inherit the earth."

In Australia Scotch thistles, English sparrows, and rabbits, three most unfortunate importations, have multiplied with equal rapidity until serious alarm fills the minds of the colonists. But in England a special committee appointed by the House of Commons to investigate the character of the alleged pest has yet to learn whether the sparrow's services as an insect-destroyer do not outweigh the injury it does to fruit and grain.

FIELD SPARROW (Spizella pusilla) Finch family

Called also: FIELD BUNTING; WOOD SPARROW; BUSH SPARROW

Length — 5.5 to 5.75 inches. A little smaller than the English sparrow. Male — Chestnut crown. Upper back bright chestnut, finely streaked with black and ashy brown. Lower back more grayish. Whitish wing-bars. Cheeks, line over the eye, throat, pale brownish drab. Tail long. Underneath grayish white, tinged with palest buff on breast and sides. Bill reddish. Female — Paler; the crown edged with grayish. Range — North America, from British provinces to the Gulf, and westward to the plains. Winters from Illinois and Virginia southward. Migrations — April. November. Common summer resident.

Simply because both birds have chestnut crowns, the field sparrow is often mistaken for the dapper, sociable chippy; and, no doubt because it loves such heathery, grassy pastures as are dear to the vesper sparrow, and has bay wings and a sweet song, these two cousins also are often confused. The field sparrow has a more reddish-brown upper back than any of its small relatives; the absence of streaks on its breast and of the white tail quills so conspicuous in the vesper sparrow's flight, sufficiently differentiate the two birds, while the red bill of the field sparrow is a positive mark of identification.

This bird of humble nature, that makes the scrubby pastures and uplands tuneful from early morning until after sunset, flies away with exasperating shyness as you approach. Alighting on a convenient branch, he lures you on with his clear, sweet song. Follow him, and he only hops about from bush to bush, farther and farther away, singing as he goes a variety of strains, which is one of the bird's peculiarities. The song not only varies in individuals, but in different localities, which may be one reason why no two ornithologists record it alike. Doubtless the chief reason for the amusing differences in the syllables into which the songs of birds are often translated in the books, is that the same Notes actually sound differently to different individuals. Thus, to people in Massachusetts the white-throated sparrow seems to say, "Pea-bod-y, Pea-bod-y, Pea-bod-y!" while good British subjects beyond the New England border hear him sing quite distinctly, "Sweet Can-a-da, Can-a-da, Can-a-da!" But however the opinions as to the syllables of the field sparrow's song may differ, all are agreed as to its exquisite quality, that resembles the vesper sparrow's tender, sweet melody. The song begins with three soft, wild whistles, and ends with a series of trills and quavers that gradually melt away into silence: a serene and restful strain as soothing as a hymn. Like the vesper sparrows, these birds sometimes build a plain, grassy nest, unprotected by over hanging bush, flat upon the ground. Possibly from a prudent tear of field-mice and snakes, the little mother most frequently lays her bluish-white, rufous — marked eggs in a nest placed in a bush of a bushy field. Hence John Burroughs has called the bird the ''bush sparrow."

FOX SPARROW (Passerella ilica) Finch family

Called also: FOX-COLORED SPARROW; FERRUGINOUS FINCH; FOXY FINCH

Length — 6.5 to 7.25 inches. Nearly an inch longer than the English sparrow. Male and Female — Upper parts reddish brown, varied with ash gray, brightest on lower back, wings, and tail. Bluish slate about the head. Underneath whitish; the throat, breast, and sides heavily marked with arrow-heads and oblong dashes of reddish brown and blackish. Range — Alaska and Manitoba to southern United States. Winters chiefly south of Illinois and Virginia. Occasional stragglers remain north most of the winter. Migrations — March. November. Most common in the migrations.

There will be little difficulty in naming this largest, most plump and reddish of all the sparrows, whose fox-colored feathers, rather than any malicious cunning of its disposition, are responsible for the name it bears. The male bird is incomparably the finest singer of its gifted family. His faint tseep call-note gives no indication of his vocal powers that some bleak morning in early March suddenly send a thrill of pleasure through you. It is the most welcome "glad surprise" of all the spring. Without a preliminary twitter or throat-clearing of any sort, the full, rich, luscious tones, with just a tinge of plaintiveness in them, are poured forth with spontaneous abandon. Such a song at such a time is enough to summon anybody with a musical ear out of doors under the leaden skies to where the delicious notes issue from the leafless shrubbery by the roadside. Watch the singer until the song ends, when he will quite likely descend among the dead leaves on the ground and scratch among them like any barn-yard fowl, but somehow contriving to use both feet at once in the operation, as no chicken ever could. He seems to take special delight in damp thickets, where the insects with which he varies his seed diet are plentiful.

Usually the fox sparrows keep in small, loose flocks, apart by themselves, for they are not truly gregarious; but they may sometimes be seen travelling in company with their white-throated cousins. They are among the last birds to leave us in the late autumn or winter. Mr. Bicknell says that they seem indisposed to sing unless present in numbers. Indeed, they are little inclined to absolute solitude at any time, for even in the nesting season quite a colony of grassy nurseries may be found in the same meadow, and small companies haunt the roadside shrubbery during the migrations.

GRASSHOPPER SPARROW (Ammodramus savannarum passerinus) Finch family

Called also: YELLOW-WINGED SPARROW

Length — 5 to 5.4 inches. About an inch smaller than the English sparrow. Male and Female — A cream-yellow line over the eye; centre of crown, shoulders, and lesser wing coverts yellowish. Head blackish; rust-colored feathers, with small black spots on back of the neck; an orange mark before the eye. All other upper parts varied red, brown, cream, and black, with a drab wash. Underneath brownish drab on breast, shading to soiled white, and without streaks. Dusky, even, pointed tail feathers have grayish-white outer margins. Range — Eastern North America, from British provinces to Cuba. Winters south of the Carolinas. Migrations — April. October. Common summer resident.

It is safe to say that no other common bird is so frequently overlooked as this little sparrow, that keeps persistently to the grass and low bushes, and only faintly lifts up a weak, wiry voice that is usually attributed to some insect. At the bend of the wings only are the feathers really yellow, and even this bright shade often goes unnoticed as the bird runs shyly through an old dairy field or grassy pasture. You may all but step upon it before it takes wing and exhibits itself on the fence-rail, which is usually as far from the ground as it cares to go. If you are near enough to this perch you may overhear the zee-e-e-e-e-e-e-e that has earned it the name of grasshopper sparrow. If you persistently follow it too closely, away it flies, then suddenly drops to the ground where a scrubby bush affords protection. A curious fact about this bird is that after you have once become acquainted with it, you find that instead of being a rare discovery, as you had supposed, it is apt to be a common resident of almost every field you walk through.

SAVANNA SPARROW (Ammodramus sandwichensis savanna) Finch family

Called also: SAVANNA BUNTING

Length — 5.5 to 6 inches. A trifle smaller than the English sparrow. Male and Female — Cheeks, space over the eye, and on the bend of the wings pale yellow. General effect of the upper parts brownish drab, streaked with black. Wings and tail dusky, the outer webs of the feathers margined with buff. Under parts white, heavily streaked with blackish and rufous, the marks on breast feathers being wedge-shaped. In the autumn the plumage is often suffused with a yellow tinge. Range — Eastern North America, from Hudson Bay to Mexico. Winters south of Illinois and Virginia. Migrations — April. October. A few remain in sheltered marshes at the north all winter.

Look for the savanna sparrow in salt marshes, marshy or upland pastures, never far inland, and if you see a sparrowy bird, unusually white and heavily streaked beneath, and with pale yellow markings about the eye and on the bend of the wing; you may still make several guesses at its identity before the weak, little insect-like trill finally establishes it. Whoever can correctly name every sparrow and warbler on sight is a person to be envied, if, indeed, he exists at all.

In the lowlands of Nova Scotia and, in fact, of all the maritime provinces, this sparrow is the one that is perhaps most commonly seen. Every fence-rail has one perched upon it, singing "Ptsip, ptsip, ptsip, ze-e-e-e-e" close to the ear of the passer-by, who otherwise might not hear the low grasshopper-like song. At the north the bird somehow loses the shyness that makes it comparatively little known farther south. Depending upon the scrub and grass to conceal it, you may almost tread upon it before it startles you by its sudden rising with a whirring noise, only to drop to the ground again just a few yards farther away, where it scuds among the underbrush and is lost to sight Tall weeds and fence-rails are as high and exposed situations as it is likely to select while singing. It is most distinctively a ground bird, and flat upon the pasture or in a slightly hollowed cup it has the merest apology for a nest. Only a few wisps of grass are laid in the cavity to receive the pale-green eggs, that are covered most curiously with blotches of brown of many shapes and tints.

SEASIDE SPARROW (Ammodramus maritimus) Finch family

Called also: MEADOW CHIPPY; SEASIDE FINCH

Length — 6 inches. A shade smaller than the English sparrow. Male and Female — Upper parts dusky grayish or olivaceous brown, inclining to gray on shoulders and on edges of some feathers. Wings and tail darkest. Throat yellowish white, shading to gray on breast, which is indistinctly mottled and streaked. A yellow spot before the eye and on bend of the wing, the bird's characteristic marks. Blunt tail. Range — Atlantic seaboard, from Georgia northward. Usually Winters south of Virginia. Migrations — April. November. A few remain in sheltered marshes all winter.

The savanna, the swamp, the sharp-tailed, and the song sparrows may all sometimes be found in the haunts of the seaside sparrow, but you may be certain of finding the latter nowhere else than in the salt marshes within sight or sound of the sea. It is a dingy little bird, with the least definite coloring of all the sparrows that have maritime inclinations, with no rufous tint in its feathers, and less distinct streakings on the breast than any of them. It has no black markings on the back.

Good-sized flocks of seaside sparrows live together in the marshes; but they spend so much of their time on the ground, running about among the reeds and grasses, whose seeds and insect parasites they feed upon, that not until some unusual disturbance in the quiet place flushes them does the intruder suspect their presence, Hunters after beach-birds, longshoremen, seaside cottagers, and whoever follows the windings of a creek through the salt meadows to catch crabs and eels in midsummer, are well acquainted with the "meadow chippies," as the fishermen call them. They keep up a good deal of chirping, sparrow-fashion, and have four or five notes resembling a song that is usually delivered from a tall reed stalk, where the bird sways and balances until his husky performance has ended, when down he drops upon the ground out of sight. Sometimes, too, these notes are uttered while the bird flutters in the air above the tops of the sedges.

SHARP-TAILED SPARROW (Ammodramus caudacutus) Finch family

Length — 5.25 to 5.85 inches. A trifle smaller than the English sparrow. Male and Female — Upper parts brownish or grayish olive, the back with black streaks, and gray edges to some feathers. A gray line through centre of crown, which has maroon stripes; gray ears enclosed by buff lines, one of which passes through the eye and one on side of throat; brownish orange, or buff, on sides of head. Bend of the wing yellow. Breast and sides pale buff, distinctly streaked with black. Underneath whitish. Each narrow quill of tail is sharply pointed. the outer ones shortest. Range — Atlantic coast. Winters south of Virginia. Migrations — April. November. Summer resident.

This bird delights in the company of the dull-colored seaside sparrow, whose haunts in the salt marshes it frequents, especially the drier parts; but its pointed tail-quills and more distinct markings are sufficient to prevent confusion. Mr. J. Dwight, Jr., who has made a special study of maritime birds, says of it: "It runs about among the reeds and grasses with the celerity of a mouse, and it is not apt to take wing unless closely pressed." (Wilson credited it with the nimbleness of a sandpiper.) "It builds its nest in the tussocks on the bank of a ditch, or in the drift left by the tide, rather than in the grassier sites chosen by its neighbors, the seaside sparrows."

Only rarely does one get a glimpse of this shy little bird, that darts out of sight like a flash at the first approach. Balancing on a cat-tail stalk or perched upon a bit of driftwood, it makes a feeble, husky attempt to sing a few notes; and during the brief performance the opera-glasses may search it out successfully. While it feeds upon the bits of sea-food washed ashore to the edge of the marshes, it gives us perhaps the best chance we ever get, outside of a museum, to study the bird's characteristics of plumage.

"Both the sharp-tailed and the seaside finches are crepuscular," says Dr. Abbott, in "The Birds About Us." They run up and down the reeds and on the water's edge long after most birds have gone to sleep.

SONG SPARROW (Melospiza fasciata) Finch family

Length — 6 to 6.5 inches. About the same size as the English sparrow. Male and Female — Brown head, with three longitudinal gray bands Brown stripe on sides of throat. Brownish-gray back streaked With rufous. Underneath gray, shading to white, heavily streaked with darkest brown. A black spot on breast. Wings without bars. Tail plain grayish brown. Range — North America, from Fur Countries to the Gulf States. Winters from southern Illinois and Massachusetts to the Gulf. Migrations — March. November. A few birds remain at the north All the year.

Here is a veritable bird neighbor, if ever there was one; at home in our gardens and hedges, not often farther away than the roadside, abundant everywhere during nearly every month in the year, and yet was there ever one too many? There is scarcely an hour in the day, too, when its delicious, ecstatic song may not be heard; in the darkness of midnight, just before dawn, when its voice is almost the first to respond to the chipping sparrow's wiry trill and the robin's warble; in the cool of the morning, the heat of noon, the hush of evening — ever the simple, homely, sweet melody that every good American has learned to love in childhood. What the bird lacks in beauty it abundantly makes up in good cheer. Not at all retiring, though never bold, it chooses some conspicuous perch on a bush or tree to deliver its outburst of song, and sings away with serene unconsciousness. Its artlessness is charming. Thoreau writes in his "Summer" that the country girls in Massachusetts hear the bird say: "Maids, maids, maids, hang on your teakettle, teakettle-ettle-ettle." The call-note, a metallic chip, is equally characteristic of the bird's irrepressible vivacity. It has still another musical expression, however, a song more prolonged and varied than its usual performance, that it seems to sing only on the wing.

Of course, the song sparrow must sometimes fly upward, but whoever sees it fly anywhere but downward into the thicket that it depends upon to conceal it from too close inspection? By pumping its tail as it flies, it seems to acquire more than the ordinary sparrow's velocity.

Its nest, which is likely to be laid flat on the ground, except where field-mice are plentiful (in which case it is elevated into the crotch of a bush), is made of grass, strips of bark, and leaves, and lined with finer grasses and hair. Sometimes three broods may be reared in a season, but even the cares of providing insects and seeds enough for so many hungry babies cannot altogether suppress the cheerful singer. The eggs are grayish white, speckled and clouded with lavender and various shades of brown.

In sparsely settled regions the song sparrows seem to show a fondness for moist woodland thickets, possibly because their tastes are insectivorous. But it is difficult to imagine the friendly little musician anything but a neighbor.

SWAMP SONG SPARROW (Melospiza georgiana) Finch family

Called also: SWAMP SPARROW [AOU 1998]; MARSH SPARROW; RED GRASS-BIRD; SWAMP FINCH

Length — 5 to 5.8 inches. A little smaller than the English sparrow. Male — Forehead black; crown, which in winter has black stripes, is always bright bay; line over the eye, sides of the neck gray. Back brown, striped with various shades. Wing. edges and tail reddish brown. Mottled gray underneath inclining to white on the chin. Female — Without black forehead and stripes on head. Range — North America, from Texas to Labrador. Migrations — April. October. A few winter at the north.

In just such impenetrable retreats as the marsh wrens choose, another wee brown bird may sometimes be seen springing up from among the sedges, singing a few sweet notes as it flies and floats above them, and then suddenly disappearing into the grassy tangle. It is too small, and its breast is not streaked enough to be a song sparrow, neither are their songs alike; it has not the wren's peculiarities of bill and tail, Its bright-bay crown and sparrowy markings finally identify it. A suggestion of the bird's watery home shows itself in the liquid quality of its simple, sweet note, stronger and sweeter than the chippy's, and repeated many times almost like a trill that seems to trickle from the marsh in a little rivulet of song. The sweetness is apt to become monotonous to all but the bird itself, that takes evident delight in its performance. In the spring, when flocks of swamp sparrows come north, how they enliven the marshes and waste places. And yet the song, simple as it is, is evidently not uttered altogether without effort, if the tail-spreading and teetering of the body after the manner of the ovenbird, are any indications of exertion.

Nuttall says of these birds: "They thread their devious way with the same alacrity as the rail, with whom, indeed, they are often associated in neighborhood. In consequence of this perpetual brushing through sedge and bushes, their feathers are frequently so worn that their tails appear almost like those of rats."

But the swamp sparrows frequently belie their name, and, especially in the South, live in dry fields, worn-out pasture lands with scrubby, weedy patches in them. They live upon seeds of grasses and berries, but Dr. Abbott has detected their special fondness for fish — not fresh fish particularly, but rather such as have lain in the sun for a few days and become dry as a chip. Their nest is placed on the ground, sometimes in a tussock of grass or roots of an upturned tree quite surrounded by water. Four or five soiled white eggs with reddish-brown spots are laid usually twice in 2 season.

TREE SPARROW (Spizella monticola) Finch family

Called also: CANADA SPARROW; WINTER CHIPPY; TREE BUNTING; WINTER CHIP-BIRD; ARCTIC CHIPPER

Length — 6 to 6.35 inches. About the same size as the English sparrow. Male — Crown of head bright chestnut. Line over the eye, cheeks, throat, and breast gray, the breast with an indistinct black spot on centre. Brown back, the feathers edged with black and buff. Lower back pale grayish brown. Two whitish bars across dusky wings; tail feathers bordered with grayish white. Underneath whitish. Female — Smaller and less distinctly marked. Range — North America, from Hudson Bay to the Carolinas, and westward to the plains. Migrations — October. April. Winter resident.

A revised and enlarged edition of the friendly little chipping sparrow, that hops to our very doors for crumbs throughout the mild weather, comes out of British America at the beginning of winter to dissipate much of the winter's dreariness by his cheerful twitterings. Why he should have been called a tree sparrow is a mystery, unless because he does not frequent trees — a reason with sufficient plausibility to commend the name to several of the early ornithologists, who not infrequently called a bird precisely what it was not. The tree sparrow actually does not show half the preference for trees that its familiar little counterpart does, but rather keeps to low bushes when not on the ground, where we usually find it. It does not crouch upon the ground like the chippy, but with a lordly carriage holds itself erect as it nimbly runs over the frozen crust. Sheltered from the high, wintry winds in the furrows and dry ditches of ploughed fields, a loose flock of these active birds keep up a merry hunt for fallen seeds and berries, with a belated beetle to give the grain a relish. As you approach the feeding ground, one bird gives a shrill alarm-cry, and instantly five times as many birds as you suspected were in the field take wing and settle down in the scrubby undergrowth at the edge of the woods or by the wayside. No still cold seems too keen for them to go a-foraging; but when cutting winds blow through the leafless thickets the scattered remnants of a flock seek the shelter of stone walls, hedges, barns, and cozy nooks about the house and garden. It is in mid-winter that these birds grow most neighborly, although even then they are distinctly less sociable than their small chippy cousins.

By the first of March, when the fox sparrow and the bluebird attract the lion's share of attention by their superior voices, we not infrequently are deaf to the modest, sweet little strain that answers for the tree sparrow's love-song. Soon after the bird is in full voice, away it goes with its flock to their nesting ground in Labrador or the Hudson Bay region. It builds, either on the ground or not far from it, a nest of grasses, rootlets, and hair, without which no true chippy counts its home complete.

VESPER SPARROW (Poocaetes gramineus) Finch family

Called also: BAY-WINGED BUNTING; GRASSFINCH; GRASSBIRD

Length — 5.75 to 6.25 inches. A little smaller than the English sparrow. Male and Female — Brown above, streaked and varied with gray. Lesser wing coverts bright rufous. Throat and breast whitish, striped with dark brown. Underneath plain soiled white. Outer tail-quills, which are its special mark of identification, are partly white, but apparently wholly white a.s the bird flies. Range — North America, especially common in eastern parts from Hudson Bay to Gulf of Mexico. Winters south of Virginia. Migrations — April. October. Common summer resident.

Among the least conspicuous birds, sparrows are the easiest to classify for that very reason, and certain prominent features of the half dozen commonest of the tribe make their identification simple even to the merest novice. The distinguishing marks of this sparrow that haunts open, breezy pasture lands and country waysides are its bright, reddish-brown wing coverts, prominent among its dingy, pale brownish-gray feathers, and its white tail-quills, shown as the bird flies along the road ahead of you to light upon the fence-rail. It rarely flies higher, even to sing its serene, pastoral strain, restful as the twilight, of which, indeed, it seems to be the vocal expression. How different from the ecstatic outburst of the song sparrow! Pensive, but not sad, its long-drawn silvery notes continue in quavers that float off unended like a trail of mist. The song is suggestive of the thoughts that must come at evening to some New England saint of humble station after a well-spent, soul-uplifting day.

But while the vesper sparrow sings oftenest and most sweetly in the late afternoon and continues singing until only he and the rose-breasted grosbeak break the silence of the early night, his is one of the first voices to join the morning chorus. No "early worm," however, tempts him from his grassy nest, for the seeds in the pasture lands and certain tiny insects that live among the grass furnish meals at all hours. He simply delights in the cool, still morning and evening hours and in giving voice to his enjoyment of them.

The vesper sparrow is preeminently a grass-bird. It first opens its eyes on the world in a nest neatly woven of grasses, laid on the ground among the grass that shelters it and furnishes it with food and its protective coloring. Only the grazing cattle know how many nests and birds are hidden in their pastures. Like the meadowlarks, their presence is not even suspected until a flock is flushed from its feeding ground, only to return to the spot when you have passed on your way. Like the meadowlark again, the vesper sparrow occasionally sings as it soars upward from its grassy home.

WHITE-CROWNED SPARROW (Zonotrichia leucophrys) Finch family

Length — 7 inches. A little larger than the English sparrow. Male — White head, with four longitudinal black lines marking off a crown, the black-and-white stripes being of about equal width. Cheeks, nape, and throat gray. Light gray underneath, with some buff tints. Back dark grayish brown. some feathers margined with gray. Two interrupted white bars across wings. Plain, dusky tail; total effect, a clear ashen gray. Female — With rusty head inclining to gray on crown. Paler throughout than the male. Range — From high mountain ranges of western United States (more rarely on Pacific slope) to Atlantic Ocean, and from Labrador to Mexico. Chiefly south of Pennsylvania. Migrations — October. April. Irregular migrant in Northern States. A winter resident elsewhere.

The large size and handsome markings of this aristocratic-looking Northern sparrow would serve to distinguish him at once, did he not often consort with his equally fine-looking white-throated cousins while migrating, and so too often get overlooked. Sparrows are such gregarious birds that it is well to scrutinize every flock with especial care in the spring and autumn, when the rarer migrants are passing. This bird is more common in the high altitudes of the Sierra Nevada and Rocky Mountains than elsewhere in the United States. There in the lonely forest it nests in low bushes or on the ground, and sings its full love song, as it does in the northern British provinces, along the Atlantic coast; but during the migrations it favors us only with selections from its repertoire. Mr. Ernest Thompson says, "Its usual song is like the latter half of the white-throat's familiar refrain, repeated a number of times with a peculiar, sad cadence and in a clear, soft whistle that is characteristic of the group." "The song is the loudest and most plaintive of all the sparrow songs," says John Burroughs. "It begins with the words fe-u, fe-u, fe-u, and runs off into trills and quavers like the song sparrow's, only much more touching." Colorado miners tell that this sparrow, like its white-throated relative, sings on the darkest nights. Often a score or more birds are heard singing at once after the habit of the European nightingales, which, however, choose to sing only in the moonlight.

WHITE-THROATED SPARROW (Zonotrichia albicollis) Finch family

Called also: PEABODY BIRD; CANADA SPARROW

Length — 6.75 to 7 inches. Larger than the English sparrow. Male and Female — A black crown divided by narrow white line. Yellow spot before the eye, and a white line, apparently running through it, passes backward to the nape. Conspicuous white throat. Chestnut back, varied with black and whitish. Breast gray, growing lighter underneath. Wings edged with rufous and with two white cross-bars. Range — Eastern North America. Nests from Michigan and Massachusetts northward to Labrador. Winters from southern New England to Florida. Migrations — April. October. Abundant during migrations, and in many States a winter resident.

"I-I, Pea-body, Pea-body, Pea-body," are the syllables of the white-throat's song heard by the good New Englanders, who have a tradition that you must either be a Peabody or a nobody there; while just over the British border the bird is distinctly understood to say, "Swee-e-e-t Can-a-da, Can-a-da, Can-a da." "All day, whit-tle-ing, whit-tle-ing, whit-tle-ing," the Maine people declare he sings; and Hamilton Gibson told of a perplexed farmer, Peverly by name, who, as he stood in the field undecided as to what crop to plant, clearly heard the bird advise, "Sow wheat, Pev-er-ly, Pev-er-ly, Pev-er-ly." Such divergence of opinion, which is really slight compared with the verbal record of many birds' songs, only goes to show how little the sweetness of birds' music, like the perfume of a rose, depends upon a name.

In a family not distinguished for good looks, the white-throated sparrow is conspicuously handsome, especially after the spring moult. In midwinter the feathers grow dingy and the markings indistinct; but as the season advances, his colors are sure to brighten perceptibly, and before he takes the northward journey in April, any little lady sparrow might feel proud of the attentions of so fine-looking and sweet-voiced a lover. The black, white, and yellow markings on his head are now clear and beautiful. His figure is plump and aristocratic.

These sparrows are particularly sociable travellers, and cordially welcome many stragglers to their flocks — not during the migrations only, but even when winter's snow affords only the barest gleanings above it. Then they boldly peck about the dog's plate by the kitchen door and enter the barn-yard, calling their feathered friends with a sharp tseep to follow them. Seeds and insects are their chosen food, and were they not well wrapped in an adipose coat under their feathers, there must be many a winter night when they would go shivering, supperless, to their perch.

In the dark of midnight one may sometimes hear the white-throat softly singing in its dreams.

GREEN, GREENISH GRAY, OLIVE, AND YELLOWISH OLIVE BIRDS

TREE SWALLOW (Tachycineta bicolor) Swallow family

Called also: WHITE-BELLIED SWALLOW

Length — 5 to 6 inches. A little shorter than the English sparrow, but apparently much larger because of its wide wing spread. Male — Lustrous dark steel-green above; darker and shading into black on wings and tail, which is forked. Under parts soft white. Female — Duller than male. Range — North America, from Hudson Bay to Panama. Migrations — End of March. September or later. Summer resident.

"The stork in the heaven knoweth her appointed times: and the turtle and the crane and the swallow observe the time of their coming." — Jeremiah, viii. 7.

The earliest of the family to appear in the spring, the tree swallow comes skimming over the freshly ploughed fields with a wide sweep of the wings, in what appears to be a perfect ecstasy of flight. More shy of the haunts of man, and less gregarious than its cousins, it is usually to be seen during migration flying low over the marshes, ponds, and streams with a few chosen friends, keeping up an incessant warbling twitter while performing their bewildering and tireless evolutions as they catch their food on the wing. Their white breasts flash in the sunlight, and it is only when they dart near you, and skim close along the surface of the water, that you discover their backs to be not black, but rich, dark green, glossy to iridescence.

It is probable that these birds keep near the waterways because their favorite insects and wax-berries are more plentiful in such places: but this peculiarity has led many people to the absurd belief that the tree swallow buries itself under the mud of ponds in winter in a state of hibernation. No bird's breathing apparatus is made to operate under mud.

In unsettled districts these swallows nest in hollow trees, hence their name; but with that laziness that forms a part of the degeneracy of civilization, they now gladly accept the boxes about men's homes set up for the martins. Thousands of these beautiful birds have been shot on the Long Island marshes and sold to New York epicures for snipe.

RUBY-THROATED HUMMING-BIRD (Trochilus colubris) Humming-bird Family

[Called also RUBY-THROATED HUMMINGBIRD, AOU 1998]

Length — 3.5 to 3.75 inches. A trifle over half as long as the English sparrow. The smallest bird we have. Male — Bright metallic green above; wings and tail darkest, with ruddy-purplish reflections and dusky-white tips on outer tail quills. Throat and breast brilliant metallic — red in one light, orange flame in another, and dusky orange in another, according as the light strikes the plumage. Sides greenish; underneath lightest gray, with whitish border outlining the brilliant breast. Bill long and needle-like. Female — Without the brilliant feathers on throat; darker gray beneath. Outer tail-quills are banded with black and tipped with white. Range — Eastern North America, from northern Canada to the Gulf Of Mexico in summer. Winters in Central America. Migrations — May. October. Common summer resident.

This smallest, most exquisite and unabashed of our bird neighbors cannot be mistaken, for it is the only one of its kin found east of the plains and north of Florida, although about four hundred species, native only to the New World, have been named by scientists. How does it happen that this little tropical jewel alone flashes about our Northern gardens? Does it never stir the spirit of adventure and emulation in the glistening breasts of its stay-at-home cousins in the tropics by tales of luxuriant tangles of honeysuckle and clematis on our cottage porches; of deep-cupped trumpet-flowers climbing over the walls of old-fashioned gardens, where larkspur, narcissus, roses, and phlox, that crowd the box-edged beds, are more gay and honey-laden than their little brains can picture? Apparently it takes only the wish to be in a place to transport one of these little fairies either from the honeysuckle trellis to the canna bed or from Yucatan to the Hudson. It is easy to see how to will and to fly are allied in the minds of the humming-birds, as they are in the Latin tongue. One minute poised in midair, apparently motionless before a flower while draining the nectar from its deep cup — though the humming of its wings tells that it is suspended there by no magic — the next instant it has flashed out of sight as if a fairy's wand had made it suddenly invisible. Without seeing the hummer, it might be, and often is, mistaken for a bee improving the "shining hour."

At evening one often hears of a "humming-bird" going the rounds of the garden, but at this hour it is usually the sphinx-moth hovering above the flower-beds — the one other creature besides the bee for which the bird is ever mistaken. The postures and preferences of this beautiful large moth make the mistake a very natural one.

The ruby-throat is strangely fearless and unabashed. It will dart among the vines on the veranda while the entire household are assembled there, and add its hum to that of the conversation in a most delightfully neighborly way. Once a glistening little sprite, quite undaunted by the size of an audience that sat almost breathless enjoying his beauty, thrust his bill into one calyx after another on a long sprig of honeysuckle held in the hand.

And yet, with all its friendliness — or is it simply fearlessness? — the bird is a desperate duellist, and will lunge his deadly blade into the jewelled breast of an enemy at the slightest provocation and quicker than thought. All the heat of his glowing throat seems to be transferred to his head while the fight continues, sometimes even to the death — a cruel, but marvellously beautiful sight as the glistening birds dart and tumble about beyond the range of peace-makers.

High up in a tree, preferably one whose knots and lichen-covered excrescences are calculated to help conceal the nest that so cleverly imitates them, the mother humming-bird saddles her exquisite cradle to a horizontal limb. She lines it with plant down, fluffy bits from cat-tails, and the fronds of fern, felting the material into a circle that an elm-leaf amply roofs over. Outside, lichens or bits of bark blend the nest so harmoniously with its surroundings that one may look long and thoroughly before discovering it. Two infinitesimal, white eggs tax the nest accommodation to its utmost.

In the mating season the female may be seen perching — a posture one rarely catches her gay lover in — preening her dainty but sombre feathers with ladylike nicety. The young birds do a great deal of perching before they gain the marvellously rapid wing-motions of maturity, but they are ready to fly within three weeks after they are hatched. By the time the trumpet-vine is in bloom they dart and sip and utter a shrill little squeak among the flowers, in company with the old birds.

During the nest-building and incubation the male bird keeps so aggressively on the defensive that he often betrays to a hitherto unsuspecting intruder the location of his home. After the young birds have to be fed he is most diligent in collecting food, that consists not alone of the sweet juices of flowers, as is popularly supposed, but also of aphides and plant-lice that his proboscis-like tongue licks off the garden foliage literally like a streak of lightning.

Both parents feed the young by regurgitation — a process disgusting to the human observer, whose stomach involuntarily revolts at the sight so welcome to the tiny, squeaking, hungry birds.

RUBY-CROWNED KINGLET (Regulus calendula) Kinglet family

Called also: RUBY-CROWNED WREN; RUBY-CROWNED WARBLER

Length — 4.25 to 4.5 inches. About two inches smaller than the English sparrow. Male — Upper parts grayish olive-green, brighter nearer the tail; wings and tail dusky, edged with yellowish olive. Two whitish wing-bars. Breast and underneath light yellowish gray. In the adult male a vermilion spot on crown of his ash-gray head. Female — Similar, but without the vermilion crest. Range — North America. Breeds from northern United States northward. Winters from southern limits of its breeding range to Central America and Mexico. Migrations — October. April. Rarely a winter resident at the North. Most common during its migrations.

A trifle larger than the golden-crowned kinglet, with a vermilion crest instead of a yellow and flame one, and with a decided preference for a warmer winter climate, and the ruby-crown's chief distinguishing characteristics are told. These rather confusing relatives would be less puzzling if it were the habit of either to keep quiet long enough to focus the opera-glasses on their crowns, which it only rarely is while some particularly promising haunt of insects that lurk beneath the rough bark of the evergreens has to be thoroughly explored. At all other times both kinglets keep up an incessant fluttering and twinkling among the twigs and leaves at the ends of the branches, jerking their tiny bodies from twig to twig in the shrubbery, hanging head downward, like a nuthatch, and most industriously feeding every second upon the tiny insects and larvae hidden beneath the bark and leaves. They seem to be the feathered expression of perpetual motion. And how dainty and charming these tiny sprites are! They are not at all shy; you may approach them quite close if you will, for the birds are simply too intent on their business to be concerned with yours.

If a sharp lookout be kept for these ruby-crowned migrants, that too often slip away to the south before we know they have come, we notice that they appear about a fortnight ahead of the golden-crested species, since the mild, soft air of our Indian summer is exactly to their liking. At this season there is nothing in the bird's "thin, metallic call-note, like a vibrating wire," to indicate that he is one of our finest songsters. But listen for him during the spring migration, when a love-song is already ripening in his tiny throat. What a volume of rich, lyrical melody pours from the Norway spruce, where the little musician is simply practising to perfect the richer, fuller song that he sings to his nesting mate in the far north! The volume is really tremendous, coming from so tiny a throat. Those who have heard it in northern Canada describe it as a flute-like and mellow warble full of intricate phrases past the imitating. Dr. Coues says of it: "The kinglet's exquisite vocalization defies description."

Curiously enough, the nest of this bird, that is not at all rare, has been discovered only six times. It would appear to be over large for the tiny bird, until we remember that kinglets are wont to have a numerous progeny in their pensile, globular home. It is made of light, flimsy material — moss, strips of bark, and plant fibre well knit together and closely lined with feathers, which must be a grateful addition to the babies, where they are reared in evergreens in cold, northern woods.

GOLDEN-CROWNED KINGLET (Regulus satrapa) Kinglet family

Called also: GOLDEN-CROWNED GOLDCREST; FIERY CROWNED WREN.

Length — 4 to 4.25 inches. About two inches smaller than the English sparrow. Male — Upper parts grayish olive-green; wings and tail dusky, margined with olive-green. Underneath soiled whitish. Centre of crown bright orange, bordered by yellow and en. closed by black line. Cheeks gray; a whitish line over the eye. Female — Similar, but centre of crown lemon-yellow and more grayish underneath. Range — North America generally. Breeds from northern United States northward. Winters chiefly from North Carolina to Central America, but many remain north all the year. Migrations — September. April. Chiefly a winter resident south Of Canada.

If this cheery little winter neighbor would keep quiet long enough, we might have a glimpse of the golden crest that distinguishes him from his equally lively cousin, the ruby-crowned; but he is so constantly flitting about the ends of the twigs, peering at the bark for hidden insects, twinkling his wings and fluttering among the evergreens with more nervous restlessness than a vireo, that you may know him well before you have a glimpse of his tri-colored crown.

When the autumn foliage is all aglow with yellow and flame this tiny sprite comes out of the north where neither nesting nor moulting could rob him of his cheerful spirits. Except the humming-bird and the winter wren, he is the smallest bird we have. And yet, somewhere stored up in his diminutive body, is warmth enough to withstand zero weather. With evident enjoyment of the cold, he calls out a shrill, wiry zee, zee, zee, that rings merrily from the pines and spruces when our fingers are too numb to hold the opera glasses in an attempt to follow his restless fittings from branch to branch. Is it one of the unwritten laws of birds that the smaller their bodies the greater their activity?

When you see one kinglet about, you may be sure there are others not far away, for, except in the nesting season, its habits are distinctly social, its friendliness extending to the humdrum brown creeper, the chickadees, and the nuthatches, in whose company it is often seen; indeed, it is likely to be in almost any flock of the winter birds. They are a merry band as they go exploring the trees together. The kinglet can hang upside down, too, like the other acrobats, many of whose tricks he has learned; and it can pick off insects from a tree with as business-like an air as the brown creeper, but with none of that soulless bird's plodding precision.

In the early spring, just before this busy little sprite leaves us to nest in Canada or Labrador — for heat is the one thing that he can't cheerfully endure — a gushing, lyrical song bursts from his tiny throat — a song whose volume is so out of proportion to the bird's size that Nuttall's classification of kinglets with wrens doesn't seem far wrong after all. Only rarely is a nest found so far south as the White Mountains. It is said to be extraordinarily large for so small a bird but that need not surprise us when we learn that as many as ten creamy-white eggs, blotched with brown and lavender, are no uncommon number for the pensile cradle to hold. How do the tiny parents contrive to cover so many eggs and to feed such a nestful of fledglings?

SOLITARY VIREO (Vireo solitarius) Vireo or Greenlet family

Called also: BLUE-HEADED VIREO [AOU 1998]

Length — 5.5 to 7 inches. A little smaller than the English sparrow. Male — Dusky olive above; head bluish gray, with a white line around the eye, spreading behind the eye into a patch. Beneath whitish, with yellow-green wash on the sides. Wings dusky olive, with two distinct white bars. Tail dusky, some quills edged with white. Female — Similar, but her head is dusky olive. Range — United States to plains, and the southern British provinces. Winters in Florida and southward. Migrations — May. Early October. Common during migrations; more rarely a summer resident south of Massachusetts.

By no means the recluse that its name would imply, the solitary vireo, while a bird of the woods, shows a charming curiosity about the stranger with opera-glasses in hand, who has penetrated to the deep, swampy tangles, where it chooses to live. Peering at you through the green undergrowth with an eye that seems especially conspicuous because of its encircling white rim, it is at least as sociable and cheerful as any member of its family, and Mr. Bradford Torrey credits it with "winning tameness." "Wood-bird as it is," he says, "it will sometimes permit the greatest familiarities. Two birds I have seen, which allowed themselves to be stroked in the freest manner, while sitting on the eggs, and which ate from my hand as readily as any pet canary."

The solitary vireo also builds a pensile nest, swung from the crotch of a branch, not so high from the ground as the yellow-throated vireos nor so exquisitely finished, but still a beautiful little structure of pine-needles, plant-fibre, dry leaves, and twigs, all lichen-lined and bound and rebound with coarse spiders' webs.

The distinguishing quality of this vireo's celebrated song is its tenderness: a pure, serene uplifting of its loving, trustful nature that seems inspired by a fine spirituality.

RED-EYED VIREO (Vireo olivaceus) Vireo or Greenlet family

Called also: THE PREACHER

Length — 5.75 to 6.25 inches. A fraction smaller than the English sparrow. Male and Female — Upper parts light olive-green; well-defined slaty-gray cap, with black marginal line, below which, and forming an exaggerated eyebrow, is a line of white. A brownish band runs from base of bill through the eye. The iris is ruby-red. Underneath white, shaded with light greenish yellow on sides and on under tail and wing coverts. Range — United States to Rockies and northward. Wnters in Central and South America. Migrations — April. October. Common summer resident.

"You see it — you know it — do you hear me? Do you believe it?" is Wilson Flagg's famous interpretation of the song of this commonest of all the vireos, that you cannot mistake with such a key. He calls the bird the preacher from its declamatory style; an up-and-down warble delivered with a rising inflection at the close and followed by an impressive silence, as if the little green orator were saying, "I pause for a reply."

Notwithstanding its quiet coloring, that so closely resembles the leaves it hunts among, this vireo is rather more noticeable than its relatives because of its slaty cap and the black-and-white lines over its ruby eye, that, in addition to the song, are its marked characteristics.

Whether she is excessively stupid or excessively kind, the mother-vireo has certainly won for herself no end of ridicule by allowing the cowbird to deposit a stray egg in the exquisitely made, pensile nest, where her own tiny white eggs are lying and though the young cowbird crowd and worry her little fledglings and eat their dinner as fast as she can bring it in, no displeasure or grudging is shown towards the dusky intruder that is sure to upset the rightful heirs out of the nest before they are able to fly.

In the heat of a midsummer noon, when nearly every other bird's voice is hushed, and only the locust seems to rejoice in the fierce sunshine, the little red-eyed vireo goes persistently about its business of gathering insects from the leaves, not flitting nervously about like a warbler, or taking its food on the wing like a flycatcher, but patiently and industriously dining where it can, and singing as it goes.

When a worm is caught it is first shaken against a branch to kill it before it is swallowed. Vireos haunt shrubbery and trees with heavy foliage, all their hunting, singing, resting, and home-building being done among the leaves — never on the ground.

WHITE-EYED VIREO (Vireo noveboracensis) Vireo or Greenlet family

Male — 5 to 5.3 inches. An inch shorter than the English sparrow. Male and Female — Upper parts bright olive-green, washed with grayish. Throat and underneath white; the breast and sides greenish yellow; wings have two distinct bars of yellowish white. Yellow line from beak to and around the eye, which has a white iris. Feathers of wings and tail brownish and edged with yellow. Range — United States to the Rockies, and to the Gulf regions And beyond in winter. Migrations — May. September. Summer resident.

"Pertest of songsters," the white-eyed vireo makes whatever neighborhood it enters lively at once. Taking up a residence in the tangled shrubbery or thickety undergrowth, it immediately begins to scold like a crotchety old wren. It becomes irritated over the merest trifles — a passing bumblebee, a visit from another bird to its tangle, an unsuccessful peck at a gnat — anything seems calculated to rouse its wrath and set every feather on its little body a-trembling, while it sharply snaps out what might perhaps be freely constructed into "cuss-words."

And yet the inscrutable mystery is that this virago meekly permits the lazy cowbird to deposit an egg in its nest, and will patiently sit upon it, though it is as large as three of her own tiny eggs; and when the little interloper comes out from his shell the mother-bird will continue to give it the most devoted care long after it has shoved her poor little starved babies out of the nest to meet an untimely death in the smilax thicket below.

An unusual variety of expression distinguishes this bird's voice from the songs of the other vireos, which are apt to be monotonous, as they are incessant. If you are so fortunate to approach the white-eyed vireo before he suspects your presence, you may hear him amusing himself by jumbling together snatches of the songs of the other birds in a sort of potpourri; or perhaps he will be scolding or arguing with an imaginary foe, then dropping his voice and talking confidentially to himself. Suddenly he bursts into a charming, simple little song, as if the introspection had given him reason for real joy. All these vocal accomplishments suggest the chat at once; but the minute your intrusion is discovered the sharp scolding, that is fairly screamed at you from an enraged little throat, leaves no possible shadow of a doubt as to the bird you have disturbed. It has the most emphatic call and song to be heard in the woods; it snaps its words off very short. "Chick-a-rer chick" is its usual call-note, jerked out with great spitefulness.

Wilson thus describes the jealously guarded nest: "This bird builds a very neat little nest, often in the figure of an inverted cone; it is suspended by the upper end of the two sides, on the circular bend of a prickly vine, a species of smilax, that generally grows in low thickets. Outwardly it is constructed of various light materials, bits of rotten wood, fibres of dry stalks, of weeds, pieces of paper (commonly newspapers, an article almost always found about its nest, so that some of my friends have given it the name of the politician); all these materials are interwoven with the silk of the caterpillars, and the inside is lined with fine, dry grass and hair."

WARBLING VIREO (Vireo gilvus) Vireo or Greenlet family

Length — 5.5 to 6 inches. A little smaller than the English sparrow. Male and Female — Ashy olive-green above, with head and neck ash-colored. Dusky line over the eye. Underneath whitish, faintly washed with dull yellow, deepest on sides; no bars on wings. Range — North America, from Hudson Bay to Mexico. Migrations — May. Late September or early October. Summer resident.

This musical little bird shows a curious preference for rows of trees in the village street or by the roadside, where he can be sure of an audience to listen to his rich, continuous warble. There is a mellowness about his voice, which rises loud, but not altogether cheerfully, above the bird chorus, as if he were a gifted but slightly disgruntled contralto. Too inconspicuously dressed, and usually too high in the tree-top to be identified without opera-glasses, we may easily mistake him by his voice for one of the warbler family, which is very closely allied to the vireos. Indeed, this warbling vireo seems to be the connecting link between them.

Morning and afternoon, but almost never in the evening, we may hear him rippling out song after song as he feeds on insects and berries about the garden. But this familiarity lasts only until nesting time, for off he goes with his little mate to some unfrequented lane near a wood until their family is reared, when, with a perceptibly happier strain in his voice, he once more haunts our garden and row of elms before taking the southern journey.

OVENBIRD (Seiurus aurocapillus) Wood Warbler family

Called also: GOLDEN-CROWNED THRUSH; THE TEACHER; WOOD WAGTAIL; GOLDEN-CROWNED WAGTAIL; GOLDEN-CROWNED ACCENTOR

Length — 6 to 6.15 inches. Just a shade smaller than the English sparrow. Male and Female — Upper parts olive, with an orange-brown crown, bordered by black lines that converge toward the bill. Under parts white; breast spotted and streaked on the sides. White eye-ring. Range — United States, to Pacific slope. Migrations — May. October. Common summer resident.

Early in May you may have the good fortune to see this little bird of the woods strutting in and out of the garden shrubbery with a certain mock dignity, like a child wearing its father's boots. Few birds can walk without appearing more or less ridiculous, and however gracefully and prettily it steps, this amusing little wagtail is no exception. When seen at all — which is not often, for it is shy — it is usually on the ground, not far from the shrubbery or a woodland thicket, under which it will quickly dodge out of sight at the merest suspicion of a footstep. To most people the bird is only a voice calling, "TEACHER TEACHER. TEACHER, TEACHER, TEACHER!" as Mr. Burroughs has interpreted the notes that go off in pairs like a series of little explosions, softly at first, then louder and louder and more shrill until the bird that you at first thought far away seems to be shrieking his penetrating crescendo into your very ears. But you may look until you are tired before you find him in the high, dry wood, never near water.

In the driest parts of the wood, here the ground is thickly carpeted with dead leaves, you may some day notice a little bunch of them, that look as if a plant, in pushing its way up through the ground, had raised the leaves, rootlets, and twigs a trifle.

Examine the spot more carefully, and on one side you find an opening, and within the ball of earth, softly lined with grass, lie four or five cream-white, speckled eggs. It is only by a happy accident that this nest of the ovenbird is discovered. The concealment could not be better. It is this peculiarity of nest construction — in shape like a Dutch oven — that has given the bird what DeKay considers its "trivial name." Not far from the nest the parent birds scratch about in the leaves like diminutive barnyard fowls, for the grubs and insects hiding under them. But at the first suspicion of an intruder their alarm becomes pitiful. Panic-stricken, they become fairly limp with fear, and drooping her wings and tail, the mother-bird drags herself hither and thither over the ground.

As utterly bewildered as his mate, the male darts, flies, and tumbles about through the low branches, jerking and wagging his tail in nervous spasms until you have beaten a double-quick retreat.

In nesting time, at evening, a very few have heard the "luxurious nuptial song" of the ovenbird; but it is a song to haunt the memory forever afterward. Burroughs appears to be the first writer to record this "rare bit of bird melody." "Mounting by easy flight to the top of the tallest tree," says the author of "Wake-Robin," "the ovenbird launches into the air with a sort of suspended, hovering flight, like certain of the finches, and bursts into a perfect ecstasy of song — clear, ringing, copious, rivalling the goldfinch's in vivacity and the linnet's in melody."

WORM-EATING WARBLER (Helmintherus vermivorus) Wood Warbler family

Length — 5.50 inches. Less than an inch shorter than the English sparrow. Male and Female — Greenish olive above. Head yellowish brown, With two black stripes through crown to the nape; also black Lines from the eyes to neck. Under parts buffy and white. Range — Eastern parts of United States. Nests as far north as southern Illinois and southern Connecticut. Winters in the Gulf States and southward. Migrations — May. September. Summer resident.

In the Delaware Valley and along the same parallel, this inconspicuous warbler is abundant, but north of New Jersey it is rare enough to give an excitement to the day on which you discover it. No doubt it is commoner than we suppose, for its coloring blends so admirably with its habitats that it is probably very often overlooked. Its call-note, a common chirp, has nothing distinguishing about it, and all ornithologists confess to having been often misled by its song into thinking it came from the chipping sparrow. It closely resembles that of the pine warbler also. If it were as nervously active as most warblers, we should more often discover it, but it is quite as deliberate as a vireo, and in the painstaking way in which it often circles around a tree while searching for spiders and other insects that infest the trunks, it reminds us of the brown creeper. Sunny slopes and hillsides covered with thick undergrowth are its preferred foraging and nesting haunts. It is often seen hopping directly on the dry ground, where it places its nest, and it never mounts far above it. The well-drained, sunny situation for the home is chosen with the wisdom of a sanitary expert.

ACADIAN FLYCATCHER (Empidonax virescens) Flycatcher family

Called also: SMALL GREEN-CRESTED FLYCATCHER; SMALL PEWEE

Length — 5.75 to 6 inches. A trifle smaller than the English sparrow. Male — Dull olive above. Two conspicuous yellowish wing-bars. Throat white, shading into pale yellow on breast. Light gray or white underneath. Upper part of bill black; lower mandible flesh-color. White eye-ring. Female — Greener above and more yellow below. Range — From Canada to Mexico, Central America, and West Indies. Most common in south temperate latitudes. Winters in southerly limit of range. Migrations — April. September. Summer resident.

When all our northern landscape takes on the exquisite, soft green, gray, and yellow tints of early spring, this little flycatcher, in perfect color-harmony with the woods it darts among, comes out of the south. It might be a leaf that is being blown about, touched by the sunshine filtering through the trees, and partly shaded by the young foliage casting its first shadows.

Woodlands, through which small streams meander lazily, inviting swarms of insects to their boggy shores, make ideal hunting grounds for the Acadian flycatcher. It chooses a low rather than a high, conspicuous perch, that other members of its family invariably select; and from such a lookout it may be seen launching into the air after the passing gnat — darting downward, then suddenly mounting upward in its aerial hunt, the vigorous clicks of the beak as it closes over its tiny victims testifying to the bird's unerring aim and its hearty appetite.

While perching, a constant tail-twitching is kept up; and a faint, fretful "Tshee-kee, tshee-kee" escapes the bird when inactively waiting for a dinner to heave in sight.

In the Middle Atlantic States its peeping sound and the clicking of its particolored bill are infrequently heard in the village streets in the autumn, when the shy and solitary birds are enticed from the deep woods by a prospect of a more plentiful diet of insects, attracted by the fruit in orchards and gardens.

Never far from the ground, on two or more parallel branches, the shallow, unsubstantial nest is laid. Some one has cleverly described it as "a tuft of hay caught by the limb from a load driven under it," but this description omits all mention of the quantities of blossoms that must be gathered to line the cradle for the tiny, cream white eggs spotted with brown.

YELLOW-BELLIED FLYCATCHER (Empidonax flaviventris) Flycatcher family

Length — 5 to 5.6 inches. About an inch smaller than the English sparrow. Male — Rather dark, but true olive-green above. Throat and breast yellowish olive, shading into pale yellow underneath, including wing linings and under tail coverts. Wings have yellowish bars. Whitish ring around eye. Upper part of bill black, under part whitish or flesh-colored. Female — Smaller, with brighter yellow under parts and more decidedly yellow wing-bars. Range — North America, from Labrador to Panama, and westward from the Atlantic to the plains. Winters in Central America. Migrations — May. September. Summer resident. More commonly a migrant only.

This is the most yellow of the small flycatchers and the only Eastern species with a yellow instead of a white throat. Without hearing its call-note, "pse-ek-pse-ek," which it abruptly sneezes rather than utters, it is quite impossible, as it darts among the trees, to tell it from the Acadian flycatcher, with which even Audubon confounded it. Both these little birds choose the same sort of retreats — well-timbered woods near a stream that attracts myriads of insects to its spongy shores — and both are rather shy and solitary. The yellow-bellied species has a far more northerly range, however, than its Southern relative or even the small green-crested flycatcher. It is rare in the Middle States, not common even in New England, except in the migrations, but from the Canada border northward its soft, plaintive whistle, which is its love-song, may be heard in every forest where it nests. All the flycatchers seem to make a noise with so much struggle, such convulsive jerkings of head and tail, and flutterings of the wings that, considering the scanty success of their musical attempts, it is surprising they try to lift their voices at all when the effort almost literally lifts them off their feet.

While this little flycatcher is no less erratic than its Acadian cousin, its nest is never slovenly. One couple had their home in a wild-grape bower in Pennsylvania; a Virginia creeper in New Jersey supported another cradle that was fully twenty feet above the ground; but in Labrador, where the bird has its chosen breeding grounds, the bulky nest is said to be invariably placed either in the moss by the brookside or in some old stump, should the locality be too swampy.

BLACK-THROATED GREEN WARBLER (Dendroica virens) Wood Warbler family

Length — 5 inches. Over an inch smaller than the English sparrow. Male — Back and crown of head bright yellowish olive-green. Forehead, band over eye, cheeks, and sides of neck rich yellow. Throat, upper breast, and stripe along sides black. Underneath yellowish white. Wings and tail brownish olive, the former with two white bars, the latter with much white in outer quills. In autumn, plumage resembling the female's. Female — Similar; chin yellowish; throat and breast dusky, the black being mixed with yellowish. Range — Eastern North America, from Hudson Bay to Central America and Mexico. Nests north of Illinois and New York. Winters in tropics. Migrations — May. October. Common summer resident north of New Jersey.

There can be little difficulty in naming a bird so brilliantly and distinctly marked as this green, gold, and black warbler, that lifts up a few pure, sweet, tender notes, loud enough to attract attention when he visits the garden. "See-see, see-saw," he sings, but there is a tone of anxiety betrayed in the simple, sylvan strain that always seems as if the bird needed reassuring, possibly due to the rising inflection, like an interrogative, of the last notes.

However abundant about our homes during the migrations, this warbler, true to the family instinct, retreats to the woods to nest — not always so far away as Canada, the nesting ground of most warblers, for in many Northern States the bird is commonly found throughout the summer. Doubtless it prefers tall evergreen trees for its mossy, grassy nest; but it is not always particular, so that the tree be a tall one with a convenient fork in an upper branch.

Early in September increased numbers emerge from the woods, the plumage of the male being less brilliant than when we saw it last, as if the family cares of the summer had proved too taxing. For nearly a month longer they hunt incessantly, with much flitting about the leaves and twigs at the ends of branches in the shrubbery and evergreens, for the tiny insects that the warblers must devour by the million during their all too brief visit.

BIRDS CONSPICUOUSLY YELLOW AND ORANGE

YELLOW-THROATED VIREO (Vireo flavifrons) Vireo or Greenlet family

Length — 5.5. to 6 inches. A little smaller than the English sparrow. Male and Female — Lemon-yellow on throat, upper breast; line around the eye and forehead. Yellow, shading into olive-green, on head, back, and shoulders. Underneath white. Tail dark brownish, edged with white. Wings a lighter shade, with two white bands across, and some quills edged with white. Range — North America, from Newfoundland to Gulf of Mexico, and westward to the Rockies. Winters in the tropics. Migrations — May. September. Spring and autumn migrant; more rarely resident.

This is undoubtedly the beauty of the vireo family — a group of neat, active, stoutly built, and vigorous little birds of yellow, greenish, and white plumage; birds that love the trees, and whose feathers reflect the coloring of the leaves they hide, hunt, and nest among. "We have no birds," says Bradford Torrey, "so unsparing of their music: they sing from morning till night."

The yellow-throated vireo partakes of all the family characteristics, but, in addition to these, it eclipses all its relatives in the brilliancy of its coloring and in the art of nest-building, which it has brought to a state of hopeless perfection. No envious bird need try to excel the exquisite finish of its workmanship. Happily, it has wit enough to build its pensile nest high above the reach of small boys, usually suspending it from a branch overhanging running water that threatens too precipitous a bath to tempt the young climbers.

However common in the city parks and suburban gardens this bird may be during the migrations, it delights in a secluded retreat overgrown with tall trees and near a stream, such as is dear to the solitary vireo as well when the nesting time approaches. High up in the trees we hear its rather sad, persistent strain, that is more in harmony with the dim forest than with the gay flower garden, where, if the truth must be told, its song is both monotonous and depressing. Mr. Bicknell says it is the only vireo that sings as it flies.

AMERICAN GOLDFINCH (Spinus tristis) Finch family

Called also: WILD CANARY; YELLOWBIRD; THISTLE BIRD

Length — 5 to 5.2 inches. About an inch smaller than the English sparrow. Male — In summer plumage: Bright yellow, except on crown of head, frontlet, wings, and tail, which are black. Whitish markings on wings give effect of bands. Tail with white on inner webs. In winter plumage: Head yellow-olive; no frontlet; black drab, with reddish tinge; shoulders and throat yellow; soiled brownish white underneath. Female — Brownish olive above, yellowish white beneath. Range — North America, from the tropics to the Fur Countries and westward to the Columbia River and California. Common throughout its range. Migrations — May-October. Common summer resident, frequently Seen throughout the winter as well.

An old field, overgrown with thistles and tall, stalky wild flowers, is the paradise of the goldfinches, summer or winter. Here they congregate in happy companies while the sunshine and goldenrod are as bright as their feathers, and cling to the swaying slender stems that furnish an abundant harvest, daintily. lunching upon the fluffy seeds of thistle blossoms, pecking at the mullein-stalks, and swinging airily among the asters and Michaelmas daisies; or, when snow covers the same field with a glistening crust, above which the brown stalks offer only a meagre dinner, the same birds, now sombrely clad in winter feathers, cling to the swaying stems with cheerful fortitude.

At your approach, the busy company rises on the wing, and with peculiar, wavy flight rise and fall through the air, marking each undulation with a cluster of notes, sweet and clear, that come floating downward from the blue ether, where the birds seem to bound along exultant in their motion and song alike.

In the spring the plumage of the goldfinch, which has been drab and brown through the winter months, is moulted or shed — a change that transforms the bird from a sombre Puritan into the gayest of cavaliers, and seems to wonderfully exalt his spirits. He bursts into a wild, sweet, incoherent melody that might be the outpouring from two or three throats at once instead of one, expressing his rapture somewhat after the manner of the canary, although his song lacks the variety and the finish of his caged namesake. What tone of sadness in his music the man found who applied the adjective tristis to his scientific name it is difficult to imagine when listening to the notes that come bubbling up from the bird's happy heart.

With plumage so lovely and song so delicious and dreamy, it is small wonder that numbers of our goldfinches are caught and caged, however inferior their song may be to the European species recently introduced into this country. Heard in Central Park, New York, where they were set at liberty, the European goldfinches seemed to sing with more abandon, perhaps, but with no more sweetness than their American cousins. The song remains at its best all through the summer months, for the bird is a long wooer. It is nearly July before he mates, and not until the tardy cedar birds are house-building in the orchard do the happy pair begin to carry grass, moss, and plant-down to a crotch of some tall tree convenient to a field of such wild flowers as will furnish food to a growing family. Doubtless the birds wait for this food to be in proper condition before they undertake parental duties at all — the most plausible excuse for their late nesting. The cares evolving from four to six pale-blue eggs will suffice to quiet the father's song for the winter by the first of September, and fade all the glory out of his shining coat. As pretty a sight as any garden offers is when a family of goldfinches alights on the top of a sunflower to feast upon the oily seeds — a perfect harmony of brown and gold.

EVENING GROSBEAK (Coccothraustes vespertinus) Finch family

Length — 8 inches. Two inches shorter than the robin. Male — Forehead, shoulders, and underneath clear yellow: dull yellow on lower back; sides of the head, throat, and breast olive-brown. Crown, tail, and wings black, the latter with white secondary feathers. Bill heavy and blunt, and yellow. Female — Brownish gray, more less suffused with yellow. Wings and tail blackish, with some white feathers. Range — Interior of North America. Resident from Manitoba northward. Common winter visitor in northwestern United States and Mississippi Valley; casual winter visitor in northern Atlantic States.

In the winter of 1889-90 Eastern people had the rare treat of becoming acquainted with this common bird of the Northwest, that, in one of its erratic travels, chose to visit New England and the Atlantic States, as far south as Delaware, in great numbers. Those who saw the evening grosbeaks then remember how beautiful their yellow plumage — a rare winter tint — looked in the snow-covered trees, where small companies of the gentle and ever tame visitors enjoyed the buds and seeds of the maples, elders, and evergreens. Possibly evening grosbeaks were in vogue for the next season's millinery, or perhaps Eastern ornithologists had a sudden zeal to investigate their structural anatomy. At any rate, these birds, whose very tameness, that showed slight acquaintance with mankind, should have touched the coldest heart, received the warmest kind of a reception from hot shot. The few birds that escaped to the solitudes of Manitoba could not be expected to tempt other travellers eastward by an account of their visit. The bird is quite likely to remain rare in the East.

But in the Mississippi Valley and throughout the northwest, companies of from six to sixty may be regularly counted upon as winter neighbors on almost every farm. Here the females keep up a busy chatting, like a company of cedar birds, and the males punctuate their pauses with a single shrill note that gives little indication of their vocal powers. But in the solitude of the northern forests the love-song is said to resemble the robin's at the start. Unhappily, after a most promising beginning, the bird suddenly stops, as if he were out of breath.

BLUE-WINGED WARBLER (Helminthophila pinus) Wood Warbler family

Called also: BLUE-WINGED YELLOW WARBLER

Length — 4.75 inches. An inch and a half shorter than the English sparrow. Male — Crown of head and all under parts bright yellow. Back olive-green. Wings and tail bluish slate, the former with white bars, and three outer tail quills with large white patches on their inner webs. Female — Paler and more olive. Range — Eastern United States, from southern New England and Minnesota, the northern limit of its nesting range, to Mexico And Central America, where it winters. Migrations — May. September. Summer resident.

In the naming of warblers, bluish slate is the shade intended when blue is mentioned; so that if you see a dainty little olive and yellow bird with slate-colored wings and tail hunting for spiders in the blossoming orchard or during the early autumn you will have seen the beautiful blue-winged warbler. It has a rather leisurely way of hunting, unlike the nervous, restless flitting about from twig to twig that is characteristic of many of its many cousins. The search is thorough — bark, stems, blossoms, leaves are inspected for larvae and spiders, with many pretty motions of head and body. Sometimes, hanging with head downward, the bird suggests a yellow titmouse. After blossom time a pair of these warblers, that have done serviceable work in the orchard in their all too brief stay, hurry off to dense woods to nest. They are usually to be seen in pairs at all seasons. Not to "high coniferous trees in northern forests," — the Mecca of innumerable warblers — but to scrubby, second growth of woodland borders, or lower trees in the heart of the woods, do these dainty birds retreat. There they build the usual warbler nest of twigs, bits of bark, leaves, and grasses, but with this peculiarity: the numerous leaves with which the nest is wrapped all have their stems pointing upward. Mr. Frank Chapman has admirably defined their song as consisting of "two drawled, wheezy notes — swee-chee, the first inhaled, the second exhaled."

CANADIAN WARBLER (Sylvania canadensis) Wood Warbler family

Called also: CANADIAN FLYCATCHER; SPOTTED CANADIAN WARBLER; [CANADA WARBLER, AOU 1998]

Length — 5 to 5.6 inches. About an inch shorter than the English sparrow. Male — Immaculate bluish ash above, without marks on wings or tail; crown spotted with arrow-shaped black marks. Cheeks, line from bill to eye, and underneath clear yellow. Black streaks forming a necklace across the breast. Female — Paler, with necklace indistinct. Range — North America, from Manitoba and Labrador to tropics. Migrations — May. September. Summer resident; most abundant in migrations.

Since about one-third of all the song-birds met with in a year's rambles are apt to be warblers, the novice cannot devote his first attention to a better group, confusing though it is by reason of its size and the repetition of the same colors in so many bewildering combinations. Monotony, however, is unknown in the warbler family. Whoever can rightly name every warbler, male and female, on sight is uniquely accomplished.

The jet necklace worn on this bird's breast is its best mark of identification. Its form is particularly slender and graceful, as might be expected in a bird so active, one to whom a hundred tiny insects barely afford a dinner that must often be caught piecemeal as it flies past. To satisfy its appetite, which cannot but be dainty in so thoroughly charming a bird, it lives in low, boggy woods, in such retreats as Wilson's black-capped warbler selects for a like reason. Neither of these two "flycatcher" warblers depends altogether on catching insects on the wing; countless thousands are picked off the under sides of leaves and about the stems of twigs in true warbler fashion.

The Canadian's song is particularly loud, sweet, and vivacious. It is hazardous for any one without long field practice to try to name any warbler by its song alone, but possibly this one's animated music is as characteristic as any.

The nest is built on the ground on a mossy bank or elevated into the root crannies of some large tree, where there is much water in the woods. Bits of bark, dead wood, moss, and fine rootlets, all carefully wrapped with leaves, go to make the pretty cradle. Unhappily, the little Canada warblers are often cheated out of their natural rights, like so many other delightful songbirds, by the greedy interloper that the cowbird deposits in their nest.

HOODED WARBLER (Sylvania mitrata) Wood Warbler family

Length — 5 to 5.75 inches. About an inch shorter than the English sparrow. Male — Head, neck, chin, and throat black like a hood in mature male specimens only. Hood restricted, or altogether wanting in female and young. Upper parts rich olive. Forehead, cheeks, and underneath yellow. Some conspicuous white on tail feathers. Female — Duller, and with restricted cowl. Range — United States east of Rockies, and from southern Michigan and southern New England to West Indies and tropical America, where it winters. Very local. Migrations — May. September. Summer resident.

This beautifully marked, sprightly little warbler might be mistaken in his immaturity for the yellowthroat; and as it is said to take him nearly three years to grow his hood, with the completed cowl and cape, there is surely sufficient reason here for the despair that often seizes the novice in attempting to distinguish the perplexing warblers. Like its Southern counterpart, the hooded warbler prefers wet woods and low trees rather than high ones, for much of its food consists of insects attracted by the dampness, and many of them must be taken on the wing. Because of its tireless activity the bird's figure is particularly slender and graceful — a trait, too, to which we owe all the glimpses of it we are likely to get throughout the summer. It has a curious habit of spreading its tail, as if it wished you to take special notice of the white spots that adorn it; not flirting it, as the redstart does his more gorgeous one, but simply opening it like a fan as it flies and darts about.

Its song, which is particularly sweet and graceful, and with more variation than most warblers' music, has been translated "Che-we-eo-tsip, tsip, che-we-eo," again interpreted by Mr. Chapman as "You must come to the woods, or you won't see me."

KENTUCKY WARBLER (Geothlypis formosa) Wood Warbler family

Length — 5.5 inches. Nearly an inch shorter than the English sparrow. Male — Upper parts olive-green; under parts yellow; a yellow line from the bill passes over and around the eye. Crown of head, patch below the eye, and line defining throat, black. Female — Similar, but paler, and with grayish instead of black markings. Range — United States eastward from the Rockies, and from Iowa and Connecticut to Central, America, where it winters. Migrations — May. September. Summer resident.

No bird is common at the extreme limits of its range, and so this warbler has a reputation for rarity among the New England ornithologists that would surprise people in the middle South and Southwest. After all that may be said in the books, a bird is either common or rare to the individual who may or may not have happened to become acquainted with it in any part of its chosen territory. Plenty of people in Kentucky, where we might judge from its name this bird is supposed to be most numerous, have never seen or heard of it, while a student on the Hudson River, within sight of New York, knows it intimately. It also nests regularly in certain parts of the Connecticut Valley. "Who is my neighbor?" is often a question difficult indeed to answer where birds are concerned. In the chapter, "Spring at the Capital," which, with every reading of "Wake Robin," inspires the bird-lover with fresh zeal, Mr. Burroughs writes of the Kentucky warbler: "I meet with him in low, damp places, in the woods, usually on the steep sides of some little run. I hear at intervals a clear, strong, bell-like whistle or warble, and presently catch a glimpse of the bird as he jumps up from the ground to take an insect or worm from the under side of a leaf. This is his characteristic movement. He belongs to the class of ground warblers, and his range is very low, indeed lower than that of any other species with which I am acquainted."

Like the ovenbird and comparatively few others, for most birds hop over the ground, the Kentucky warbler walks rapidly about, looking for insects under the fallen leaves, and poking his inquisitive beak into every cranny where a spider may be lurking. The bird has a pretty, conscious way of flying up to a perch, a few feet above the ground, as a tenor might advance towards the footlights of a stage, to pour forth his clear, penetrating whistle, that in the nesting season especially is repeated over, and over again with tireless persistency.

MAGNOLIA WARBLER (Dendroica maculosa) Wood Warbler family

Called also: BLACK-AND-YELLOW WARBLER; SPOTTED WARBLER; BLUE-HEADED YELLOW-RUMPED WARBLER

Length — 4.75 to 5 inches. About an inch and a half smaller than the English sparrow. Male — Crown of head slate-color, bordered on either side by a white line; a black line, apparently running through the eye, and a yellow line below it, merging into the yellow throat. Lower back and under parts yellow. Back, wings, and tail blackish olive. Large white patch on the wings, and the middle of the tail-quills white. Throat and sides heavily streaked with black. Female — Has greener back, is paler, and has less distinct markings. Range — North America, from Hudson Bay to Panama. Summers from northern Michigan and northern New England northward; winters in Central America and Cuba. Migrations — May. October. Spring and summer migrant.

In spite of the bird's name, one need not look for it in the glossy magnolia trees of the southern gardens more than in the shrubbery on New England lawns, and during the migrations it is quite as likely to be found in one place as in the other. Its true preference, however, is for the spruces and hemlocks of its nesting ground in the northern forests. For these it deserts us after a brief hunt about the tender, young spring foliage and blossoms, where the early worm lies concealed, and before we have become so well acquainted with its handsome clothes that we will instantly recognize it in the duller ones it wears on its return trip in the autumn. The position of the white marks on the tail feathers of this warbler, however, is the clue by which it may be identified at any season or any stage of its growth. If the white bar runs across the middle of the warbler's tail, you can be sure of the identity of the bird. A nervous and restless hunter, it nevertheless seems less shy than many of its kin. Another pleasing characteristic is that it brings back with it in October the loud, clear, rapid whistle with which it has entertained its nesting mate in the Canada woods through the summer.

MOURNING WARBLER (Geothlypis philadelphia) Wood Warbler family

Called also: MOURNING GROUND WARBLER

Length — 5 to 5.6 inches. About an inch smaller than the English sparrow. Male — Gray head and throat; the breast gray; the feathers with black edges that make them look crinkled, like crape. The black markings converge into a spot on upper breast. Upper parts, except head, olive. Underneath rich yellow. Female — Similar, but duller; throat and breast buff and dusky where the male is black. Back olive-green. Range — "Eastern North America; breeds from eastern Nebraska, northern New York, and Nova Scotia northward, and south ward along the Alleghanies to Pennsylvania. Winters in the tropics." — Chapman. Migrations — May. September. Spring and autumn migrant.

Since Audubon met with but one of these birds in his incessant trampings, and Wilson secured only an immature, imperfectly marked specimen for his collection, the novice may feel no disappointment if he fails to make the acquaintance of this "gay and agreeable widow." And yet the shy and wary bird is not unknown in Central Park, New York City. Even where its clear, whistled song strikes the ear with a startling novelty that invites to instant pursuit of the singer, you may look long and diligently through the undergrowth without finding it. Dr. Merriam says the whistle resembles the syllables "true, true, true, tru, too, the voice rising on the first three syllables and falling on the last two." In the nesting season this song is repeated over and over again with a persistency worthy of a Kentucky warbler. It is delivered from a perch within a few feet of the ground, as high as the bird seems ever inclined to ascend.
