Our burros were tethered for the day in a grassy hollow, our effects stowed away in the cabin aforesaid, which we had leased for a few days; then, with luncheon strapped over our shoulders and butterfly net and field-glass in hand, we started happily up the valley afoot toward the summit of our aspirations, Gray's Peak, rising fourteen thousand four hundred and forty-one feet above the level of the sea. In some scrubby pine bushes above timber-line several Audubon's warblers were flitting and singing, living hard by the white fields of snow. Still farther up the hollow Wilson's warblers were trilling blithely, proclaiming themselves yet more venturesome than their gorgeous cousins, the Audubons. There is reason for this difference, for Wilson's warblers nest in willows and other bushes which thrive on higher ground and nearer the snowy zone than do the pines to which Audubon's warblers are especially attached. At all events, Sylvania pusilla was one of the two species which accompanied us all the way from Georgetown to the foot of Gray's Peak, giving us a kind of "personally conducted" journey.

Our other brave escorts were the white-crowned sparrows, which pursued the narrowing valleys until they were merged into the snowy gorges that rive the sides of the towering twin peaks. In the arctic gulches the scrubby copses came to an end, and therefore the white-crowns ascended no higher, for they are, in a pre-eminent sense, "birds of the bush." Subsequently I found them as far up the sides of Mount Kelso as the thickets extended, which was hundreds of feet higher than the snow-bound gorges just mentioned, for Kelso receives more sunshine than his taller companions, particularly on his eastern side. Brave birds are these handsome and musical sparrows. It was interesting to see them hopping about on the snow-fields, picking up dainties from the white crystals. How lyrical they were in this upper mountain valley! As has been said, for some unaccountable reason the white-crowns in the vicinity of Georgetown were quite chary of their music. Not so those that dwelt in the valley below Gray's and Torrey's peaks, for there they trilled their melodious measures with a richness and abandon that were enchanting.

On reaching the snow-belt, though still a little below the limit of copsy growths, we saw our first pipits, which, it will be remembered, I had encountered on the summit of Pike's Peak two years before. In our climb up Gray's Peak we found the pipit realm and that of the white-crowned sparrows slightly overlapping. As soon, however, as we began the steep climb above the matted copses, the white-crowns disappeared and the pipits grew more abundant. At frequent intervals these birds would suddenly start up from the ground, utter their protesting "Te-cheer! te-cheer!" and hurl themselves recklessly across a snowy gulch, or dart high into the air and let their semi-musical calls drop and dribble from the turquoise depths of the sky. Did the pipits accompany you to the summit of the peak? I half regret to admit that they did not, but ceased to appear a good while before the summit was attained. This is all the more remarkable when it is remembered that these birds were extremely abundant on the crest of Pike's Peak, where they behaved in a "very-much-at-home" way.

However, there was ample compensation in the ascent of Gray's Peak. As we clambered up the steep and rugged side of the mountain, sometimes wading snow up to our knees, then making a short cut straight up the acclivity to avoid the snow-banks, unable to follow the trail a large part of the way, we were suddenly made aware of the presence of another fearless feathered comrade. With a chirp that was the very quintessence of good cheer and lightness of heart, he hopped about on the snow, picking dainties from his immaculate tablecloth, and permitting us to approach him quite close before he thought it worth while to take to wing. We were happy indeed to meet so companionable a little friend, one that, amid these lonely and awe-inspiring heights, seemed to feel so much at ease and exhibited so confiding a disposition. Was it fancy or was it really true? He appeared to be giving us a hospitable welcome to his alpine home, telling us we might venture upward into cloudland or skyland without peril; then, to make good his assurance, he mounted upward on resilient wings to prove how little danger there was. We were doubly glad for our little seer, for just then we needed someone to "prophesy smooth things" to us. The bird was the brown-capped leucosticte or rosy finch. Thus far I have used the singular number, but the plural would have been more accurate, for there were many of these finches on the acclivity and summit, all of them in a most cheerful mood, their good will and cordial welcome giving us a pleasant feeling of comradery as we journeyed together up the mountain side.

Our climb up Gray's Peak was a somewhat memorable event in our experience, and I am disposed to dwell upon it. The valley which we had followed terminates in a deep gorge, filled with drift snow the year round, no doubt, and wedging itself between Gray's and Torrey's shoulders and peaks. Here the melting snows form the head waters of Clear Creek, whose sinuous course we had followed by rail, foot, and burro from the city of Denver.

The trail, leaving the ravine, meandered up a shoulder of the mountain, wheeled to the left and crept along a ridge, with some fine, blood-curdling abysses on the eastern side; then went zigzagging back and forth on the precipitous wall of Gray's titanic mount, until at last, with a long pull and a strong pull, it scaled the backbone of the ridge. All this, however, is much more easily told than done. Later in the season, when the trail is clear of snow-drifts, sure-footed horses and burros are ridden to the summit; but we were too early to follow the trail even on foot. Indeed, many persons familiar with the mountains had declared that we could not reach the top so early in the season, on account of the large snow-banks that still covered the trail. Even the old miner, who in the valley below pointed out the peak to us, expressed grave doubts about the success and wisdom of our undertaking. "See!" he said, "the trail's covered with snow in many places on the mountain side. I'm afraid you can't reach the top, sir." I did not see as clearly as he did, but said nothing aloud. In my mind I shouted, "Excelsior!" and then added, mentally, of course, "Faint heart never won fair lady or fairer mountain's crest—hurrah for the peak!" I simply felt that if there were birds and butterflies on that sky-aspiring tower, I must see them. The die was cast; we had come to Colorado expressly to climb Gray's Peak, and climb it we would, or have some good reason to give for not doing so.

And now we were making the attempt. We had scarcely reached the mountain's shoulder before we were obliged to wade snow. For quite a distance we were able to creep along the edge of the trail, or skirt the snow-beds by making short detours, and then returning to the trail; but by and by we came to a wide, gleaming snow-field that stretched right athwart our path and brought us to a standstill with the exclamation, "What shall we do now?" Having already sunk a number of times into the snow over our boot-tops, we felt that it would not be safe to venture across so large an area of soft and treacherous crystals melting in the afternoon sun and only slightly covering we knew not what deep gorges. In some places we had been able to walk on the top of the snow, but elsewhere it was quite soft, and we could hear the gurgling of water underneath, and sometimes it sounded a little more sepulchral than we liked. Looking far up the acclivity, we saw still larger snow-fields obliterating the trail. "We can never cross those snow-fields," one of us declared, a good deal of doubt in his tones. A moment's reflection followed, and then the other exclaimed stoutly, "Let us climb straight up, then!" To which his companion replied, "All right, little Corporal! Beyond the Alps lies Italy!"

Over rocks and stones and stretches of gravel, sometimes loose, sometimes solid, we clambered, half the time on all fours, skirting the snow-fields that lay in our unblazed pathway; on and up, each cheering the other at frequent intervals by crying lustily, "We can make it! We can make it!" ever and anon throwing ourselves on the rocks to recover our breath and rest our aching limbs; on and up we scrambled and crept, like ants on a wall, until at length, reaching the ridge at the left a little below the top, we again struck the trail, when we stopped a few minutes to catch breath, made one more mighty effort, and, behold! we stood on Gray's summit, looking down triumphantly at the world crouching at our feet. Never before had we felt so much like Jupiter on Olympus.

GRAY'S AND TORREY'S PEAKS

Gray's to the left, Torrey's to the right. As the lookout of the photographer was nearer Torrey's than Gray's, the former appears the higher in the picture, while the reverse is really the case. The trail winds through a ravine at the right of the ridge in front; then creeps along the farther side of the ridge above the gorge at Torrey's base; comes to the crest of the ridge pretty well toward the left; then crawls and zigzags back and forth along the titanic wall of Gray's to the summit. In the vale, where some of the head waters of Clear Creek will be seen, the white-crowned sparrows and Wilson's warblers find homes. A little before the ascent of the ridge begins, the first pipits are seen; thence the clamberer has pipit company to the point where the ridge joins the main bulk of the mountain. Here the pipits stop, and the first leucostictes are noted, which, chirping cheerily all the way, escort the traveller to the summit.



In making the ascent, some persons, even among those who ride, become sick; others suffer with bleeding at the nose, and others are so overcome with exhaustion and weakness that they cannot enjoy the superb panorama spread out before them. However you may account for it, my youthful comrade and I, in spite of our arduous climb, were in excellent physical condition when we reached our goal, suffering no pain whatever in eyes, head, or lungs. The bracing air, rare as it was, soon exhilarated us, our temporary weariness disappeared, and we were in the best of trim for scouring the summit, pursuing our natural history hobbies, and revelling in the inspiring cyclorama that Nature had reared for our delectation.

My pen falters when I think of describing the scene that broke upon our vision. I sigh and wish the task were done. The summit itself is a narrow ridge on which you may stand and look down the declivities on both sides, scarcely having to step out of your tracks to do so. It is quite different from the top of Pike's Peak, which is a comparatively level plateau several acres in extent, carpeted, if one may so speak, with immense granite rocks piled upon one another or laid side by side in semi-systematic order; whereas Gray's, as has been said, is a narrow ridge, composed chiefly of comparatively small stones, with a sprinkling of good-sized boulders. The finer rocks give the impression of having been ground down by crushing and attrition to their present dimensions in the far-away, prehistoric ages.

A short distance to the northwest frowned Torrey's Peak, Gray's companion-piece, the twain being connected by a ridge which dips in an arc perhaps a hundred feet below the summits. The ridge was covered with a deep drift of snow, looking as frigid and unyielding as a scene in the arctic regions. Torrey's is only a few feet lower than Gray's—one of my books says five. Mention has been made of its forbidding aspect. It is indeed one of the most ferocious-looking mountains in the Rockies, its crown pointed and grim, helmeted with snow, its sides, especially east and north, seamed and ridged and jagged, the gorges filled with snow, the beetling cliffs jutting dark and threatening, bearing huge drifts upon their shoulders. Torrey's Peak actually seemed to be calling over to us like some boastful Hercules, "Ah, ha! you have climbed my mild-tempered brother, but I dare you to climb me!" For reasons of our own we declined the challenge.

The panorama from Gray's Peak is one to inspire awe and dwell forever in the memory, an alpine wonderland indeed and in truth. To the north, northwest, and west there stretches, as far as the eye can reach, a vast wilderness of snowy peaks and ranges, many of them with a rosy glow in the sunshine, tier upon tier, terrace above terrace, here in serried ranks, there in isolated grandeur, some just beyond the dividing canyons, others fifty, sixty, a hundred miles away, cyclopean, majestic, infinite. Far to the north, Long's Peak lifts his seamed and hoary pyramid, almost as high as the crest on which we are standing; in the west rise that famous triad of peaks, Harvard, Yale, and Princeton, their fanelike towers, sketched against the sky, disputing the palm with old Gray himself; while a hundred miles to the south Pike's Peak stands solitary and smiling in the sun, seeming to say, "I am sufficient unto myself!" Between our viewpoint and the last-named mountain lies South Park, like a paradise of green immured by guardian walls of rock and snow, and far to the east, beyond the billowing ranges, white, gray, and green, stretch the limitless plains, vanishing in the hazy distance. In such surroundings one's breast throbs and swells with the thought of Nature's omnipotence.

PANORAMA FROM GRAY'S PEAK—NORTHWEST

The picture includes the northern spur of Gray's Peak, with the dismantled signal station on its crest. The main ridge of the peak extends out to the left of the signal station. The summit is so situated as to be exposed to the sun the greater part of the day; hence, although it is the highest point in the region, there is less snow upon it in summer than upon many of the surrounding elevations. Looking northwest from the signal station, the eye falls upon a wilderness of snow-clad peaks and ranges, some standing in serried ranks, others in picturesque disorder. It is truly an arctic scene, summer or winter. Yet it is the summer home of the brown-capped leucosticte and the white-tailed ptarmigan, which range in happy freedom over the upper story of our country.



The summit of Gray's Peak is a favorable viewpoint from which to study the complexion, the idiosyncrasies, if you please, of individual mountains, each of which seems to have a personality of its own. Here is Gray's Peak itself, calm, smiling, good-natured as a summer morning; yonder is Torrey's, next-door neighbor, cruel, relentless, defiant, always threatening with cyclone or tornado, or forging the thunder-bolts of Vulcan. Some mountains appear grand and dignified, others look like spitfires. On one side some bear smooth and green slopes almost to the top, while the other is scarred, craggy, and precipitous.

The day was serene and beautiful, the sky a deep indigo, unflecked with clouds, save a few filmy wracks here and there, and the breeze as balmy as that of a May morning in my native State. So quiet was the alpine solitude that on all sides we could hear the solemn roar of the streams in the ravines hundreds of feet below, some of them in one key and some in another, making almost a symphony. For several hours we tarried, held by a spell. "But you have forgotten your ornithology!" some one reminds me. No one could blame me if I had. Such, however, is not the case, for ornithology, like the poor, is never far from some of us. The genial little optimists that had been hopping about on the snow on the declivities had acted as our cicerones clear to the summit, and some of them remained there while we tarried. Indeed the leucostictes were quite plentiful on the mountain's brow. Several perched on the dismantled walls of the abandoned government building on the summit, called cheerily, then wheeled about over the crest, darted out and went careering over the gulches with perfect aplomb, while we watched them with envious eyes, wishing we too had wings like a leucosticte, not that we "might fly away," as the Psalmist longed to do, but that we might scale the mountains at our own sweet will. The favorite occupation of our little comrades, besides flying, was hopping about on the snow and picking up dainties that were evidently palatable. Afterwards we examined the snow, and found several kinds of small beetles and other insects creeping up through it or about on its surface. Without doubt these were leucosticte's choice morsels. Thus Nature spreads her table everywhere with loving care for her feathered children. The general habits of the rosy finches are elsewhere depicted in this volume. It only remains to be said that they were much more abundant and familiar on Gray's Peak than on Pike's Peak,—that is, at the time of my respective visits to those summits.



To omit all mention of the butterflies seen on this trip would be proof of avian monomania with a vengeance. The lad who was with me found a number of individuals of two species zigzagging over the summit, and occasionally settling upon the rocks right by the fields of snow. What kind of nectar they sipped I know not, for there were no flowers or verdure on the heights. They were the Painted Lady or Thistle Butterfly (Pyrameis cardui) and the Western White (Pieris occidentalis). He captured an individual of the latter species with his net, and to-day it graces his collection, a memento of a hard but glorious climb. The descent of the mountain was laborious and protracted, including some floundering in the snow, but was accomplished without accident. A warm supper in the miner's shack which we had leased prepared us for the restful slumbers of the night.

Although the weather was so cold that a thin coating of ice was formed on still water out of doors, the next morning the white-crowned sparrows were singing their sonatas long before dawn, and when at peep of day I stepped outside, they were flitting about the cabins as if in search of their breakfast. The evening before, I left the stable-door open while I went to bring the burros up from their grazing plat. When I returned with the animals, a white-crown flew out of the building just as I stepped into the entrance, almost fluttering against my feet, and chirping sharply at what he seemed to think a narrow escape. He had doubtless gone into the stable on a foraging expedition.

The day was spent in exploring the valley and steep mountain sides. A robin's nest was found a little below the timber-line on the slope of Mount Kelso. In the woods a short distance farther down, a gray-headed junco's nest was discovered after a good deal of patient waiting. A female was preening her feathers on a small pine-tree, a sure sign that she had recently come from brooding her eggs. Presently she began to flit about from the tree to the ground and back again, making many feints and starts, which proved that she was embarrassed by my espionage; but at last she disappeared and did not return. With quickened pulse I approached the place where I had last seen her. It was not long before she flew up with a nervous chirp, revealing a pretty domicile under a roof of green grass, with four daintily speckled eggs on the concave floor. I noticed especially that the doorway of the tiny cottage was open toward the morning sun.

At the timber-line there were ruby-crowned kinglets, mountain chickadees, and gray-headed juncos, while far above this wavering boundary a pair of red-shafted flickers were observed ambling about among the bushes and watching me as intently as I was watching them. I climbed far up the side of Mount Kelso, then around its rocky shoulder, following an old trail that led to several abandoned silver mines, but no new birds rewarded my toilsome quest, although I was pleased to learn that the pipits and leucostictes did not give the "go-by" to this grand old mountain, but performed their thrilling calisthenics in the air about its slopes and ravines with as much grace as they did on the loftier mountain peaks the day before. A beautiful fox and three cubs were seen among the large stones, and many mountain rats and a sly mink went scuttling about over the rocks.



On the morning of June 30 the white-crowns, as usual, were chanting their litanies long before day broke. We left the enchanting valley that morning, the trills of the white-crowns ringing in the alpenglow like a sad farewell, as if they felt that we should never meet again. On our way down the winding road we frequently turned to gaze with longing eyes upon the snowy summits of the twin peaks, Gray's all asmile in the sunshine, and Torrey's—or did we only imagine it?—relenting a little now that he was looking upon us for the last time. Did the mountains and the white-crowns call after us, "Auf wiedersehen!" or was that only imagination too?



PLEASANT OUTINGS



One of our pleasantest trips was taken up South Platte Canyon, across South Park, and over the range to Breckenridge. The town lies in the valley of the Blue River, the famous Ten Mile Range, with its numerous peaks and bold and rugged contour, standing sentinel on the west. Here we found many birds, but as few of them were new, I need not stop to enter into special detail.

At the border of the town I found my first green-tailed towhee's nest, which will be described in the last chapter. A pair of mountain bluebirds had snuggled their nest in a cranny of one of the cottages, and an entire family of blues were found on the pine-clad slope beyond the stream; white-crowned sparrows were plentiful in the copses and far up the bushy ravines and mountain sides; western chippies rang their silvery peals; violet-green swallows wove their invisible fabrics overhead; juncos and Audubon's warblers proclaimed their presence in many a remote ingle by their little trills; and Brewer's blackbirds "chacked" their remonstrance at every intrusion into their demesnes; while in many a woodsy or bushy spot the long-crested jays rent the air with their raucous outcries; nor were the broad-tailed hummers wanting on this side of the range, and of course their saucy buzzing was heard wherever they darted through the air.

An entire day was spent in ascending and descending Peak Number Eight, one of the boldest of the jutting crags of the Ten Mile Range; otherwise it is called Tillie Ann, in honor of the first white woman known to scale its steep and rugged wall to the summit. She must have been a brave and hardy woman, and certainly deserves a monument of some kind in memory of her achievement, although it falls to the lot of few persons to have their deeds celebrated by a towering mountain for a memorial. While not as high by at least a thousand feet as Gray's Peak, it was fully as difficult of access. A high ridge of snow, which we surmounted with not a little pride and exhilaration, lay on its eastern acclivity within a few feet of the crest, a white crystalline bank gleaming in the sun. The winds hurtling over the summit were as cold and fierce as old Boreas himself, so that I was glad to wear woollen gloves and button my coat-collar close around my neck; yet it was the Fourth of July, when the people of the East were sweltering in the intense heat of their low altitudes. It was a surprise to us to find the wind so much colder here than it had been on the twenty-eighth of June on the summit of Gray's Peak, which is considerably farther north. However, there may be times when the meteorological conditions of the two peaks are reversed, blowing a gale on Gray's and whispering a zephyr on Tillie Ann.

The usual succession of birds was seen as we toiled up the slopes and steep inclines, some stopping at the timber-line and others extending their range far up toward the alpine zone. In the pine belt below the timber-line a pair of solitaires were observed flitting about on the ground and the lower branches of the trees, but vouchsafing no song. In the same woodland the mountain jays held carnival—a bacchanalian revel, judging from the noise they made; the ruby-crowned kinglets piped their galloping roundels; a number of wood-pewees—western species—were screeching, thinking themselves musical; siskins were flitting about, though not as numerous as they had been in the piny regions below Gray's Peak; and here for the first time I saw olive-sided flycatchers among the mountains. I find by consulting Professor Cooke that their breeding range is from seven thousand to twelve thousand feet. A few juncos and ruby-crowned kinglets were seen above the timber-line, while many white-crowned sparrows, some of them singing blithely, climbed as far up the mountain side as the stunted copses extended.

Oddly enough, no leucostictes were seen on this peak. Why they should make their homes on Pike's and Gray's Peaks and neglect Tillie Ann is another of those puzzles in featherdom that cannot be solved. Must a peak be over fourteen thousand feet above sea-level to meet their physiological wants in the summery season? Who can tell? There were pipits on this range, but, for some reason that was doubtless satisfactory to themselves, they were much shyer than their brothers and sisters had been on Gray's Peak and Mount Kelso; more than that, they were seen only on the slopes of the range, none of them being observed on the crest itself, perhaps on account of the cold, strong gale that was blowing across the snowy heights. A nighthawk was sailing in its erratic course over the peaks—a bit of information worth noting, none of these birds having been seen on any of the summits fourteen thousand feet high. These matters are perhaps not of supreme interest, yet they have their value as studies in comparative ornithology and are helpful in determining the locale of the several species named. In the same interest I desire to add that mountain chickadees, hermit thrushes, warbling vireos, and red-shafted flickers belong to my Breckenridge list. Besides, what I think must have been a Mexican crossbill was seen one morning among the pines, and also a large hawk and two kinds of woodpeckers, none of which tarried long enough to permit me to make sure of their identity. The crossbill—if the individual seen was a bird of that species—wore a reddish jacket, explored the pine cones, and sang a very respectable song somewhat on the grosbeak order, quite blithe, loud, and cheerful.

On our return trip to Denver we stopped for a couple of days at the quiet village of Jefferson in South Park, and we shall never cease to be thankful that our good fairies led us to do so. What birds, think you, find residence in a green, well-watered park over nine thousand feet above sea-level, hemmed in by towering, snow-clad mountains? Spread out around you like a cyclorama lies the plateau as you descend the mountain side from Kenosha Pass; or wheel around a lofty spur of Mount Boreas, and you almost feel as if you must be entering Paradise. It was the fifth of July, and the park had donned its holiday attire, the meadows wearing robes of emerald, dappled here and there with garden spots of variegated flowers that brought more than one exclamation of delight from our lips.

SOUTH PARK FROM KENOSHA HILL

A paradise of green engirdled by snow-mantled mountains, making a summer home for western meadow-larks, Brewer's blackbirds, desert horned larks, and western Savanna sparrows.



Before leaving the village, our attention was called to a colony of cliff-swallows, the first we had seen in our touring among the mountains. Against the bare wall beneath the eaves of a barn they had plastered their adobe, bottle-shaped domiciles, hundreds of them, some in orderly rows, others in promiscuous clusters. At dusk, when we returned to the village, the birds were going to bed, and it was interesting to watch their method of retiring. The young were already grown, and the entire colony were converting their nests into sleeping berths, every one of them occupied, some of the partly demolished ones by two and three birds. But there were not enough couches to go round, and several of the birds were crowded out, and were clinging to the side of the wall on some of the protuberances left from their broken-down clay huts. It was a query in my mind whether they could sleep comfortably in that strained position, but I left them to settle that matter for themselves and in their own way.

Leaving the town, we soon found that the irrigated meadows and bush-fringed banks of the stream made habitats precisely to the taste of Brewer's blackbirds, which were quite plentiful in the park. My companion was "in clover," for numerous butterflies went undulating over the meadows, leading him many a headlong chase, but frequently getting themselves captured in his net. Thus occupied, he left me to attend to the birds. At the border of the village a little bird that was new to me flitted into view and permitted me to identify it with my glass. The little stranger was the western savanna sparrow. South Park was the only place in my Colorado rambles where I found this species, and even his eastern representative is known to me very imperfectly and only as a migrant. The park was fairly alive with savannas, especially in the irrigated portions. I wonder how many millions of them dwelt in this vast Eden of green almost twice as large as the State of Connecticut! The little cocks were incessant singers, their favorite perches being the wire fences, or weeds and grass tufts in the pastures. Their voices are weak, but very sweet, and almost as fine as the sibilant buzz of certain kinds of insects. The pretty song opens with two or three somewhat prolonged syllables, running quite high, followed by a trill much lower in the scale, and closes with a very fine, double-toned strain, delivered with the rising inflection and a kind of twist or jerk—"as if," say my notes, "the little lyrist were trying to tie a knot in his aria before letting it go." More will be said about these charming birds before the end of this chapter.

The western meadow-larks were abundant in the park, delivering with great gusto their queer, percussive chants, which, according to my notes, "so often sound as if the birds were trying to crack the whip." The park was the only place above the plains and mesas where I found these gifted fluters, with the exception of the park about Buena Vista. It would appear that the narrow mountain valleys, green and grassy though they are, do not appeal to the larks for summer homes; no, they seem to crave "ampler realms and spaces" in which to spread their wings and chant their dithyrambs.

Where the natural streams and irrigating ditches do not reach the soil of the park it is as dry and parched as the plains and mesas. In fact, the park is only a smaller and higher edition of the plains, the character of the soil and the topography of the land in both regions being identical. Never in the wet, fresh meadows, whether of plain or park, only on the arid slopes and hillocks, will you find the desert horned larks, which are certainly true to their literary cognomen, if ever birds were. How they revel in the desert! How scrupulously they draw the line on the moist and emerald areas! Surely there are "many birds of many kinds," and one might appropriately add, "of many minds," as well; for, while the blackbirds and savanna sparrows eschew the desert, the horned larks show the same dislike for the meadow. In shallow pits dug by themselves amid the sparse buffalo grass, the larks set their nests. The young had already left their nurseries at the time of my visit to the park, but were still receiving their rations from the beaks of their elders. On a level spot an adult male with an uncommonly strong voice for this species was hopping about on the ground and reciting his canticles. Seeing I was a stranger and evidently interested in all sorts of avian exploits, he decided to give an exhibition of what might be called sky-soloing, as well as dirigible ballooning. Starting up obliquely from the ground, he continued to ascend in a series of upward leaps, making a kind of aerial stairway, up, up, on and up, until he was about the size of a humming-bird framed against the blue dome of the sky. So far did he plunge into the cerulean depths that I could just discern the movement of his wings. While scaling the air he did not sing, but having reached the proper altitude, he opened his mandibles and let his ditty filtrate through the ether like a shower of spray. It could be heard quite plainly, although at best the lark's song is a weak, indefinite twitter, its peculiar characteristic being its carrying quality, which is indeed remarkable.

The soloist circled around and around in the upper air so long that I grew dizzy watching him, and my eyes became blinded by the sun and the glittering sky. How long he kept up his aerial evolutions, singing all the while, I am unprepared to announce, for I was too much engrossed in watching him to consult my timepiece; but the performance lasted so long that I was finally obliged to throw myself on my back on the ground to relieve the strain upon me, so that I might continue to follow his movements. I venture the conjecture that the show lasted from fifteen to twenty minutes; at least, it seemed that long to me in my tense state of body and mind. Finally he shot down like an arrow, making my head fairly whirl, and landed lightly on the ground, where he skipped about and resumed his roundelay as if he had not performed an extraordinary feat. This was certainly skylarking in a most literal sense. With the exception of a similar exhibition by Townsend's solitaire—to be described in the closing chapter—up in the neighborhood of Gray's Peak, it was the most wonderful avian aeronautic exploit, accompanied with song, of which I have ever been witness. It is odd, too, that a bird which is so much of a groundling—I use the term in a good sense, of course—should also be so expert a sky-scraper. I had listened to the sky song of the desert horned lark out on the plain, but there he did not hover long in the air.

The killdeer plovers are as noisy in the park as they are in an eastern pasture-field, and almost as plentiful. In the evening near the village a pair of western robins and a thieving magpie had a hard tussle along the fence of the road. The freebooter was carrying something in his beak which looked sadly like a callow nestling. He tried to hide in the fence-corners, to give himself a chance to eat his morsel, but they were hot on his trail, and at length he flew off toward the distant ridge. Where did the robins build their nests? I saw no trees in the neighborhood, but no doubt they built their adobe huts on a fence-rail or in a nook about an old building. Not a Say's phoebe had we thus far seen on this jaunt to the mountains, but here was a family near the village, and, sure enough, they were whistling their likely tunes, the first time I had ever heard them. While I had met with these birds at Glenwood and in the valley below Leadville, they had not vouchsafed a song. What is the tune they whistle? Why, to be sure, it is, "Phe-be-e! phe-be-e! phe-e-e-bie!" Their voices are stronger and more mellifluent than the eastern phoebe's, but the manner of delivery is not so sprightly and gladsome. Indeed, if I mistake not, there is a pensive strain in the lay of the western bird.

A few cowbirds, red-winged blackbirds, and spotted sandpipers were seen in the park, but they are too familiar to merit more than casual mention. However, let us return to Brewer's blackbirds. Closely as they resemble the bronzed grackles of the East, there are some marked differences between the eastern and western birds; the westerners are not so large, and their manners and nesting habits are more like those of the red-wings than the grackles. Brewer's blackbirds hover overhead as you come into the neighborhood of their nests or young, and the males utter their caveats in short squeals or screeches and the females in harsh "chacks."



The nests are set in low bushes and even on the ground, while those of the grackles are built in trees and sometimes in cavities. To be exact and scientific, Brewer's blackbirds belong to the genus Icolecophagus, and the grackles to the genus Quiscalus. In the breeding season the western birds remain in the park. That critical period over, in August and September large flocks of them, including young and old, ascend to favorite feeding haunts far above the timber-line, ranging over the slopes of the snowy mountains engirdling their summer home. Then they are in the heyday of blackbird life. Silverspot himself, made famous by Ernest Thompson Seton, did not lead a more romantic and adventurous life, and I hope some day Brewer's blackbird will be honored by a no less effective biography.

What a to-do they make when you approach their outdoor hatchery! Yet they are sly and diplomatic. One day I tried my best to find a nest with eggs or bantlings in it, but failed, although, as a slight compensation, I succeeded in discovering three nests from which the young had flown. The old birds of both sexes circled overhead, called and pleaded and scolded, and sometimes swooped down quite close to my scalp, always veering off in time to avoid actual collision. A pair of them held choice morsels—choice for Brewer's blackbirds—in their bills, and I sat down on a tuft of sod and watched them for a couple of hours, hoping they would feed their young in plain sight and divulge their secret to me; but the sable strategists flitted here and there, hovered in the air, dropped to the ground, visiting every bush and grass-tuft but the right one, and finally the worms held in their bills disappeared, whether into their own gullets or those of their fledgelings, I could not tell. If the latter, the rascals were unconscionably wary, for my eyes were bent on them every moment—at least, I thought so. Again and again they flew off some distance, never more than a stone's throw, strutted about for a few minutes among the tufts of grass and sod, then came back with loud objurgations to the place where I sat. They seemed to be aware of my inspection the moment my field-glass was turned upon them, for they would at once cease their pretended search for insects in the grass and fly toward me with a clamorous berating giving me a big piece of their mind. At length my patience was worn out; I began to hunt for nests, and found the three empty abodes to which allusion has been made.

For the most part the female cried, "Chack! chack!" but occasionally she tried to screech like her ebon consort, her voice breaking ludicrously in the unfeminine effort. The evening before, I had flushed a youngster about which a great hubbub was being made, but on the day of my long vigil in the meadow, I could not, by the most careful search, find a single bantling, either in or out of a nest. It is odd how effectually the young are able to conceal themselves in the short grass and straggling bushes.

Not a little attention was given to the western savanna sparrows, whose songs have already been described. Abundant proof was furnished that the breeding season for these little birds was at its height, and I determined to find a nest, if within the range of possibility. An entire forenoon was spent in discovering three nests. As you approach their domiciles, the cocks, which are always on the alert, evidently give the alarm to their sitting mates, which thereupon slip surreptitiously from the nest; and in that case how are you going to ferret out their domestic secrets?

A female—I could distinguish her from her consort by her conduct—was sitting on the post of a wire fence, preening her feathers, which was sufficient evidence that she had just come from brooding her eggs. To watch her until she went back to her nest, then make a bee-line for it—that was the plan I resolved to pursue. It is an expedient that succeeds with many birds, if the observer is very quiet and tactful. For a long time I stood in the blazing sun with my eyes bent on the little impostor. Back and forth, hither and yon, she flew, now descending to the ground and creeping slyly about in the grass, manifestly to induce me to examine the spot; then back to the fence again, chirping excitedly; then down at another place, employing every artifice to make me think the nest was where it was not; but I steadfastly refused to budge from my tracks as long as she came up in a few moments after descending, for in that case I knew that she was simply resorting to a ruse to lead me astray. Finally she went down at a point which she had previously avoided, and, as it was evident she was becoming exceedingly anxious to go back upon her eggs, I watched her like a tiger intent on his prey. Slyly she crept about in the grass, presently her chirping ceased, and she disappeared.

Several minutes passed, and she did not come up, so I felt sure she had gone down for good this time, and was sitting on her nest. Her husband exerted himself to his utmost to beguile my attention with his choicest arias, but no amount of finesse would now turn me from my purpose. I made a bee-line for the spot where I had last seen the madame, stopping not, nor veering aside for water, mud, bushes, or any other obstacle. A search of a couple of minutes brought no find, for she had employed all the strategy of which she was mistress in going to the nest, having moused along in the grass for some distance after I had last seen her. I made my search in an ever-widening circle, and at length espied some dry grass spears in a tuft right at my feet; then the little prospective mother flitted from her nest and went trailing on the ground, feigning to be fatally wounded.

Acquainted with such tactics, I did not follow her, not even with my eye, but looked down at my feet. Ah! the water sprites had been kind, for there was the dainty crib, set on a high tuft of sod raised by the winter's frosts, a little island castle in the wet marsh, cosey and dry. It was my first savanna sparrow's nest, whether eastern or western. The miniature cottage was placed under a fragment of dried cattle excrement, which made a slant roof over it, protecting it from the hot rays of the sun. Sunken slightly into the ground, the nest's rim was flush with the short grass, while the longer stems rose about it in a green, filmy wall or stockade. The holdings of the pretty cup were four pearls of eggs, the ground color white, the smaller end and middle peppered finely with brown, the larger almost solidly washed with pigment of the same tint.

Two more savannas' nests were found not long afterwards, one of them by watching the female until she settled, the other by accidentally flushing her as I walked across the marshy pasture; but neither of them was placed under a roof as the first one had been, the blue dome being their only shelter. These birdlets seem to be especially fond of soggy places in pastures, setting their nests on the little sod towers that rise above the surrounding water.

All the birds seen in the park have now been mentioned. It was an idyllic spot, and I have often regretted that I did not spend a week in rambling over it and making excursions to the engirdling ridges and peaks. A few suggestive questions arise relative to the migratory habits of the feathered tenants of a mountain park like this, for most of those that have been named are only summer residents. How do they reach this immured Eden at the time of the spring migration? One may conjecture and speculate, but one cannot be absolutely sure of the precise course of their annual pilgrimage to their summer Mecca. Of course, they come up from the plains, where the spring arrives much earlier than it does in the higher altitudes. Our nomads may ascend by easy stages along the few canyons and valleys leading up from the plains to this mountain-girt plateau; or else, rising high in air at eventide—for most birds perform their migrations at night—they may fly over the passes and mountain tops, and at dawn descend to the park.

Neither of these hypotheses is free from objection, for, on the one hand, it is not likely that birds, which cannot see in the dark, would take the risk of dashing their brains out against the cliffs and crags of the canyons by following them at night; yet they may depart from their usual habit of nocturnal migration, and make the journey up the gorges and vales by day. On the other hand, the nights are so cold in the elevated regions that the little travellers' lives might be jeopardized by nocturnal flight over the passes and peaks. There is one thing certain about the whole question, perplexing as it may be—the feathered pilgrims reach their summer quarters in some way, and seem to be very happy while they remain.

We stopped at a number of places in our run down South Platte Canyon, adding no new birds to our list, but making some interesting observations. At Cassel's a house-wren had built a nest on the veranda of the hotel where people were sitting or passing most of the time, and was feeding her tiny brood. In the copse of the hollow below the resort, the mountain song-sparrows were trilling sweetly—the only ones we had encountered in our wanderings since leaving Arvada on the plains. These musicians seem to be rather finical in their choice of summer resorts. Chaseville is about a mile below Cassel's, and was made memorable to us by the discovery of our second green-tailed towhee's nest, a description of which I have decided to reserve for the last chapter of this volume. Lincoln's sparrows descanted in rich tones at various places in the bushy vales, but were always as wild as deer, scuttling into the thickets before a fair view of them could be obtained.

The veranda of a boarding-house at Shawnee was the site of another house-wren's nest. While I stood quite close watching the little mother, she fed her bantlings twice without a quaver of fear, the youngsters chirping loudly for more of "that good dinner." At this place barn swallows were describing graceful circles and loops in the air, and a sheeny violet-green swallow squatted on the dusty road and took a sun-bath, which she did by fluffing up all her plumes and spreading out her wings and tail, so that the rays could reach every feather with their grateful warmth and light. It was a pretty performance.



A stop-over at Bailey's proved satisfactory for several reasons, among which was the finding of the Louisiana tanagers, which were the first we had seen on this trip, although many of them had been observed in the latitude of Colorado Springs. Afterwards we found them abundant in the neighborhood of Boulder. The only pigmy nuthatches of this visit were seen in a ravine above Bailey's. In the same wooded hollow I took occasion to make some special notes on the quaint calls of the long-crested jays, a task that I had thus far deferred from time to time. There was an entire family of jays in the ravine, the elders feeding their strapping youngsters in the customary manner. These birds frequently give voice to a strident call that is hard to distinguish from the cries of their kinsmen, the mountain jays. When I pursued the couple that were attending to the gastronomical wants of their children, one of the adults played a yodel on his trombone sounding like this: "Ka-ka-ka, k-wilt, k-wilt, k-wilt", the first three short syllables enunciated rapidly, and the "k-wilts" in a more measured way, with a peculiar guttural intonation, giving the full sound to the k and w. The birds became very shy when they thought themselves shadowed, not understanding what my pursuit might imply, and they gave utterance to harsh cries of warning that were different from any that had preceded. It was presently followed by a soft and friendly chatter, as if the birds were having an interview that was exclusively inter se. Then one of them startled me by breaking out in a loud, high key, crying, "Quick! quick! quick!" as fast as he could fling the syllables from his tongue. This, being translated into our human vernacular, obviously meant, "Hurry off! danger! danger!" A few minutes of silence followed the outburst, while the birds ambled farther away, and then the echoes were roused by a most raucous call, "Go-ware! go-ware! go-ware!" in a voice that would have been enough to strike terror to the heart of one who was not used to uncanny sounds in solitary places. After that outburst the family flew off, and I could hear them talking the matter over among themselves far up the mountain side, no doubt congratulating one another on their hair-breadth escape. The youngsters looked quite stylish with their quaint little blue caps and neatly fitting knickerbockers.

At Bailey's I found my first and only white-crowned sparrow's nest for this trip, although two years before I was fortunate enough to discover several nests in the valleys creeping from the foot of Pike's Peak. At dusk one evening I was walking along the railway below the village, listening to the sweetly pensive trills of the white-crowns in the bushes bordering the creek, when there was a sharp chirp in the willows, and a female white-crown darted over to my side of the stream and slipped quietly into a thick bush on the bank. I stepped down to the spot, and the pretty madame leaped away, uncovering a well-woven nest containing four white eggs speckled with dark brown. All the while her spouse was trilling with might and main on the other side of the creek, to make believe that there was nothing serious happening, no nest that any one cared anything about. His mate could not disguise her agitation by assuming nonchalance, but flitted about in the willows and chirped pitifully. I hurried away to relieve her distress. The cottages on the slopes were gay with tourists enjoying their summer outing, and beautiful Kiowa Lodge, perched on a shoulder of the mountain among embowering pines, glowed with incandescent lights, while its blithe-hearted guests pursued their chosen kinds of pastime; but none of them, I venture to assert, were happier than the little white-crown in her grassy lodge on the bank of the murmuring stream.

On the way down the canyon, as we were going to Denver, I was able to add three belted kingfishers to my bird-roll of Colorado species, the only ones I saw in the Rockies.

Our jaunt of 1901 included a trip to Boulder and a thrilling swing around the far-famed "Switzerland Trail" to Ward, perched on the mountain sides among the clouds hard by the timber-line. Almost everywhere we met with feathered comrades; in some places, especially about Boulder, many of them; but no new species were seen, and no habits observed that have not been sufficiently delineated in other parts of this book. If one could only observe all the birds all the time in all places, what a happy life the bird-lover would live! It is with feelings of mingled joy and sadness that one cons Longfellow's melodious lines:—

"Think every morning when the sun peeps through The dim, leaf-latticed windows of the grove, How jubilant the happy birds renew Their old, melodious madrigals of love! And when you think of this, remember too 'Tis always morning somewhere, and above The awakened continents, from shore to shore, Somewhere the birds are singing evermore."



A NOTABLE QUARTETTE[12]

On the plains of Colorado there dwells a feathered choralist that deserves a place in American bird literature, and the day will perhaps come when his merits will have due recognition, and then he shall have not only a monograph, but also an ode all to himself.

[12] The author is under special obligation to Mr. John P. Haines, editor of "Our Animal Friends," and president of the American Society for the Prevention of Cruelty to Animals, for publishing the contents of this chapter in his magazine in time to be included in this volume. Also for copyright privileges in connection with this and other chapters.

The bird to which I refer is called the lark bunting in plain English, or, in scientific terms, Calamospiza melanocorys. The male is a trig and handsome fellow, giving you the impression of a well-dressed gentleman in his Sunday suit of black, "with more or less of a slaty cast," as Ridgway puts it, the middle and greater wing-coverts bearing a conspicuous white patch which is both a diagnostic marking and a real ornament. In flight this patch imparts to the wing a filmy, almost semi-transparent, aspect. The bunting is about the size of the eastern bobolink, and bears some resemblance to that bird; but bobolink he is not, although sometimes mistaken for one, and even called by that name in Colorado. The fact is, those wise men, the systematists, have decided that the bobolink belongs to the family Icteridae, which includes, among others, the blackbirds and orioles, while the lark bunting occupies a genus all by himself in the family Fringillidae—that is, the family of finches, sparrows, grosbeaks, and towhees. Therefore, the two birds can scarcely be called second cousins. The bunting has no white or buff on his upper parts.

Sitting on a sunny slope one June evening, I surrendered myself to the spell of the bunting, and endeavored to make an analysis of his minstrelsy. First, it must be said that he is as fond as the bobolink of rehearsing his arias on the wing, and that is, perhaps, the chief reason for his having been mistaken for that bird by careless observers. Probably the major part of his solos are recited in flight, although he can sit quietly on a weed-stalk or a fence-post and sing as sweetly, if not as ecstatically, as if he were curveting in the air. During this aerial performance he hovers gracefully, bending his wings downward, after the bobolink's manner, as if he were caressing the earth beneath him. However, a striking difference between his intermittent song-flights and those of the bobolink is to be noted. The latter usually rises in the air, soars around in a curve, and returns to the perch from which he started, or to one near by, describing something of an ellipse. The lark bunting generally rises obliquely to a certain point, then descends at about the same angle to another perch opposite the starting-point, describing what might be called the upper sides of an isosceles triangle, the base being a line near the ground, connecting the perch from which he rose and the one on which he alighted. I do not mean to say that our bunting never circles, but simply that such is not his ordinary habit, while sweeping in a circle or ellipse is the favorite pastime of the eastern bobolink. The ascent of neither bird is very high. They are far from deserving the name of skylarks.

We must give a detailed account of the bunting's song. Whatever others may think of him, I have come under the spell of his lyrical genius. True, his voice has not the loud, metallic ring, nor his chanson the medley-like, happy-go-lucky execution, that marks the musical performances of the bobolink; but his song is more mellow, rhythmic, theme-like; for he has a distinct tune to sing, and sing it he will. In fine, his song is of a different order from that of the bobolink, and, therefore, the comparison need be carried no further.

As one of these minstrels sat on a flowering weed and gave himself up to a lyrical transport, I made careful notes, and now give the substance of my elaborate entries. The song, which is intermittent, opens with three prolonged notes running high in the scale, and is succeeded by a quaint, rattling trill of an indescribable character, not without musical effect, which is followed by three double-toned long notes quite different from the opening phrases; then the whole performance is closed by an exceedingly high and fine run like an insect's hum—so fine, indeed, that the auditor must be near at hand to notice it at all. Sometimes the latter half of the score, including the second triad of long notes, is repeated before the soloist stops to take breath. It will be seen that the regular song consists of four distinct phrases, two triads and two trills. About one-third of the songs are opened in a little lower key than the rest, the remainder being correspondingly mellowed. The opening syllables, and, indeed, some other parts of the melody as well, are very like certain strains of the song-sparrow, both in execution and in quality of tone; and thus even the experienced ornithologist may sometimes be led astray. When the bunting sails into the air, he rehearses the song just described, only he is very likely to prolong it by repeating the various parts, though I think he seldom, if ever, throws them together in a hodge-podge. He seems to follow a system in his recitals, varied as many of them are. As to his voice, it is of superb timbre.

Another characteristic noted was that the buntings do not throw back their heads while singing, after the manner of the sparrows, but stretch their necks forward, and at no time do they open their mouths widely. As a rule, or at least very often, when flying, they do not begin their songs until they have almost reached the apex of their triangle; then the song begins, and it continues over the angle and down the incline until another perch is settled upon. What Lowell says of "bobolinkum" is just as true of bunting—"He runs down, a brook o' laughter, thru the air." As the sun went down behind the snow-clad mountains, a half dozen or more of the buntings rolled up the full tide of song, and I left them to their vespers and trudged back to the village, satisfied with the acquirements of this red-letter day in my ornithological journey.

However, one afternoon's study of such charming birds was not enough to satisfy my curiosity, for no females had been seen and no nests discovered. About ten days later, more attention was given them. In a meadow not far from the hamlet of Arvada, between Denver and the mountains, I found a colony of buntings one morning, swinging in the air and furnishing their full quota of the matutinal concert, in which many other birds had a leading part, among them being western meadow-larks, western robins, Bullock's orioles, American and Arkansas goldfinches, mountain song-sparrows, lazuli finches, spurred towhees, black-headed grosbeaks, summer warblers, western Maryland yellow-throats, and Townsend's solitaires. It has seldom been my fortune to listen to a finer pot-pourri of avian music.

At first only male buntings were seen. Surely, I thought, there must be females in the neighborhood, for when male birds are singing so lustily about a place, their spouses are usually sitting quietly on nests somewhere in bush or tree or grass. I hunted long for a nest, trudging about over the meadow, examining many a grass-tuft and weed-clump, hoping to flush a female and discover her secret; but my quest was vain. It is strange how difficult it is to find nests in Colorado, either on the plains or in the mountains. The birds seem to be adepts in the fine arts of concealment and secret-keeping. Presently several females were seen flying off over the fields and returning, obviously to feed their young. There was now some colorable prospect of finding a nest. A mother bird appeared with a worm in her bill, and you may rely upon it I did not permit her to slip from my sight until I saw her drop to the ground, hop about stealthily for a few moments, then disappear, and presently fly up minus the worm. Scarcely daring to breathe, I followed a direct course to the weed-clump from which she had risen. And there was a nest, sure enough—my first lark bunting's—set in a shallow pit of the ground, prettily concealed and partly roofed over by the flat and spreading weed-stalk. Four half-fledged youngsters lay panting in the little cradle, the day being very warm. I lifted one of them from the nest, and held it in my hand for a minute or two, and even touched it with my lips, my first view of lark-bunting babies being something of an event—I had almost said an epoch—in my experience. Replacing the youngster in its crib, I stepped back a short distance and watched the mother bird returning with another mouthful of "goodies," and feeding her bantlings four. She was not very shy, and simply uttered a fine chirp when I went too close to her nestlings, while her gallant consort did not even chirp, but tried to divert my attention by repeatedly curveting in the air and singing his choicest measures. This was the only bunting's nest I found, although I made long and diligent search for others, as you may well believe when I state that a half day was spent in gathering the facts recorded in the last two paragraphs.

In the afternoon I watched a female in another field for a long time, but she was too wary to betray her secret. In this case the male, instead of beguiling me with song, flitted about and mingled his fine chirps with those of his anxious mate. On my way across the plains, some two weeks later, I discovered that the lark buntings do not dwell only in well-watered meadows, but also in the most arid localities. Still, I am inclined to think they do not build their nests far from refreshing streams. When the breeding season is over, they range far and wide over the plains in search of insects that are to their taste. From the car window many of them were observed all along the way to a distance of over sixty miles east of Denver. At that time the males, females, and young were moving from place to place, mostly in scattering flocks, the breeding season being past. A problem that puzzled me a little was where they obtain water for drinking and bathing purposes, but no doubt such blithe and active birds are able to "look out for number one."

The second member of our lyrical quartette is the elegant green-tailed towhee, known scientifically as Pipilo chlorurus. The pretty green-tails are quite wary about divulging their domestic secrets, and for a time I was almost in despair of finding even one of their nests. In vain I explored with exhausting toil many a steep mountain side, examining every bush and beating every copse within a radius of many rods.

My purpose was to flush the female from her nest, a plan that succeeds with many birds; but in this instance I was disappointed. It is possible that, when an intruder appears in their nesting haunts, the males, which are ever on the lookout, call their spouses from the nests, and then "snap their fingers," so to speak, at the puzzled searcher.

However, by watching the mother birds carrying worms in their bills I succeeded in finding two nests. The first was at Breckenridge, and, curiously enough, in a vacant lot at the border of the town, not on a steep slope, but on a level spot near the bank of Blue River. The mother bird had slyly crept to her nest while I watched, and remained firmly seated until I bent directly over her, when she fluttered away, trailing a few feet to draw my attention to herself. It was a cosey nest site—in a low, thick bush, beneath a rusty but well-preserved piece of sheet-iron which made a slant roof over the cradle. It contained three callow bantlings, which innocently opened their carmine-lined mouths when I stirred the leaves above them. It seemed to be an odd location for the nest of a bird that had always appeared so wild and shy. The altitude of the place is nine thousand five hundred and twenty feet.

My second green-tail's nest was in South Platte Canyon, near a station called Chaseville, its elevation being about eight thousand five hundred feet. I was walking along the dusty wagon road winding about the base of the mountain, when a little bird with a worm in her bill flitted up the steep bank a short distance and disappeared among the bushes. The tidbit in her bill gave me a clew to the situation; so I scrambled up the steep place, and presently espied a nest in a bush, about a foot and a half from the ground. As had been anticipated, it turned out to be a green-tailed towhee's domicile, as was proved by the presence and uneasy chirping of a pair of those birds. While the nest at Breckenridge was set on the ground, this one was placed on the twigs of thick bushes, showing that these birds, like their eastern relatives, are fond of diversity in selecting nesting places.

This nest contained four bantlings, already well fledged. My notes say that their mouths were yellow-lined, and that the fleshy growths at the corners of their bills were yellow. Does the lining of the juvenile green-tail's mouth change from red to yellow as he advances in age? My notes certainly declare that the nestlings at Breckenridge had carmine-lined mouths. For the present I cannot settle the question either affirmatively or negatively.

Here I perpetrated a trick which I have ever since regretted. The temptation to hold a baby green-tail in my hand and examine it closely was so strong that, as carefully as I could, I drew one from its grassy crib and held it in my palm, noting the green tinting already beginning to show on its wings and back. Its tail was still too stubby to display the ornamentation that gives the species its popular name. So much was learned, but at the expense of the little family's peace of mind. As I held the bantling in my hand, the frightened mamma uttered a series of pitiful calls that were new to my ears, consisting of two notes in a low, complaining tone; it was more of an entreaty than a protest. Afterwards I heard the green-tails also give voice to a fine chirp almost like that of a chipping sparrow.

The mother's call seemed to strike terror to the hearts of her infant brood, for, as I attempted to put the baby back into its crib, all four youngsters set up a loud to-do, and sprang, panic stricken, over the rim, tumbling, fluttering, and falling through the network of twigs to the ground, a couple of them rolling a few feet down the dusty bank. Again and again I caught them and put them back into the nest, but they would not remain there, so I was compelled to leave them scrambling about among the bushes and rocks. I felt like a buccaneer, a veritable Captain Kidd. My sincere hope is that none of the birdkins came to grief on account of their premature flight from the nest. The next morning old and young were chirping about the place as I passed, and I hurried away, feeling sad that science and sentiment must sometimes come into conflict.

One day in the latter part of June, as I was climbing the steep side of a mesa in the neighborhood of Golden, my ear was greeted by a new style of bird music, which came lilting sweetly down to me from the height. It had a kind of wild, challenging ring about it, as if the singer were daring me to venture upon his demesne at my peril. A hard climb brought me at length within range of the little performer, who was blowing his Huon's horn from the pointed top of a large stone on the mesa's side. My field-glass was soon fixed upon him, revealing a little bird with a long beak, decurved at the end, a grayish-brown coat quite thickly barred and mottled on the wings and tail, and a vest of warm white finely sprinkled with a dusky gray. A queer, shy, timid little thing he was. Afterwards I met him often, but never succeeded in gaining his confidence or winning a single concession from him. He was the rock wren (Salpinctes obsoletus)—a species that is unknown east of the Great Plains, one well deserving a place in literature.

I was especially impressed with his peculiar style of minstrelsy, so different from anything I had ever heard in the bird realm. While the song was characterized by much variety, it usually opened with two or three loud, clear syllables, somewhat prolonged, sounding, as has been said, like a challenge, followed by a peculiar bubbling trill that seemed fairly to roll from the piper's tongue. Early one morning a few days later I heard a brilliant vocalist descanting from the top of a pump in a wide field among the foothills. How wildly his tones rang out on the crisp morning air! I seemed to be suddenly transported to another part of the world, his style of music was so new, so foreign to my ear. My pencilled notes say of this particular minstrel: "Very musical—great variety of notes—clear, loud, ringing—several runs slightly like Carolina's—others suggest Bewick's—but most of them sui generis."

Let us return to the first rock wren I saw. He was exceedingly shy, scurrying off to a more distant perch—another stone—as I approached. Sometimes he would run down among the bushes and rocks like a mouse, then glide to the top of another stone, and fling his pert little aria at the intruder. It was interesting to note that he most frequently selected for a singing perch the top of a high, pointed rock where he could command a view of his surroundings and pipe a note of warning to his mate at the approach of a supposed enemy. Almost every conspicuous rock on the acclivity bore evidence of having been used as a lookout by the little sentinel.

This wren is well named, for his home is among the rocks, in the crannies and niches of which his mate hides her nest so effectually that you must look long for it, and even after the most painstaking search you may not be able to find it. The little husband helps to lead you astray. He will leap upon a rock and send forth his bell-like peal, as if he were saying, "Right here, right here, here is our nest!" but when you go to the spot, he flits off to another rock and sounds the same challenge. And so you can form no idea of the nest site. My nearest approach to finding a nest was among the rocks and cliffs on the summit of a mountain a few miles from Golden, where an adult bird was seen to feed a youngster that had already flown from the nursery. It was interesting to know that the rock wrens breed at so high an altitude. However, they are not an alpine species, none having been seen by the writer over eight thousand feet above sea-level, although they have been known to ascend to an altitude of twelve thousand feet.

The fourth member of our feathered quartette was the oddest of all. On the thirtieth of June my companion and I were riding slowly down the mountain side a few miles below Gray's Peak, which we had scaled two days before. My ear was struck by a flicker's call above us, so I dismounted from my burro, and began to clamber up the hillside. Presently I heard a song that seemed one moment to be near at hand, the next far away, now to the right, now to the left, and anon directly above me. To my ear it was a new kind of bird minstrelsy. I climbed higher and higher, and yet the song seemed to be no nearer. It had a grosbeak-like quality, I fancied, and I hoped to find either the pine or the evening grosbeak, for both of which I had been making anxious search. The shifting of the song from point to point struck me as odd, and it was very mystifying.

Higher and higher I climbed, the mountain side being so steep that my breath came in gasps, and I was often compelled to throw myself on the ground to recover strength. At length a bird darted out from the pines several hundred feet above me, rose high into the air, circled and swung this way and that for a long time, breaking at intervals into a song which sifted down to me faintly through the blue distance. How long it remained on the wing I do not know, but it was too long for my eyes to endure the strain of watching it. Through my glass a large part of the wings showed white or yellowish-white, and seemed to be almost translucent in the blaze of the sunlight. What could this wonderful haunter of the sky be? It was scarcely possible that so roly-poly a bird as a grosbeak could perform so marvellous an exploit on the wing.

I never worked harder to earn my salary than I did to climb that steep and rugged mountain side; but at last I reached and penetrated the zone of pines, and finally, in an area covered with dead timber, standing and fallen, two feathered strangers sprang in sight, now flitting among the lower branches and now sweeping to the ground. They were not grosbeaks, that was sure; their bills were quite slender, their bodies lithe and graceful, and their tails of well-proportioned length. Save in color, they presented a decidedly thrush-like appearance, and their manners were also thrush-like.

Indeed, the colors and markings puzzled me not a little. The upper parts were brownish-gray of various shades, the wings and tail for the most part dusky, the wing-coverts, tertials, and some of the quills bordered and tipped with white, also the tail. The white of both wings and tail became quite conspicuous when they were spread. This was the feathered conundrum that flitted about before me. The birds were about the size of the hermit thrushes, but lither and suppler. They ambled about gracefully, and did not seem to be very shy, and presently one of them broke into a song—the song that I had previously heard, only it was loud and ringing and well articulated, now that I was near the singer. Again and again they lifted their rich voices in song. When they wandered a little distance from each other, they called in affectionate tones, giving their "All's well."

Then one of them, no doubt the male, darted from a pine branch obliquely into the air, and mounted up and up and up, in a series of graceful leaps, until he was a mere speck against the blue dome, gyrating to and fro in zigzag lines, or wheeling in graceful circles, his song dribbling faintly down to me at frequent intervals. A thing of buoyancy and grace, more angel than bird, that wonderful winged creature floated about in the cerulean sky; how long I do not know, whether five minutes, or ten, or twenty, but so long that at last I flung myself upon my back and watched him until my eyes ached. He kept his wings in constant motion, the white portions making them appear filmy as the sun shone upon them. Suddenly he bent his head, partly folded his wings, and swept down almost vertically like an arrow, alighting safe somewhere among the pines. I have seen other birds performing aerial evolutions accompanied with song, but have never known one to continue so long on the wing.

What was this wonderful bird? It was Townsend's solitaire (Myadestes townsendii)—a bird which is peculiar to the West, especially to the Rocky Mountains, and which belongs to the same family as the thrushes and bluebirds. No literature in my possession contains any reference to this bird's astonishing aerial flight and song, and I cannot help wondering whether other bird-students have witnessed the interesting exploit.

Subsequently I found a pair of solitaires on the plains near Arvada. The male was a powerful singer. Many of his outbursts were worthy of the mocking-bird, to some of whose runs they bore a close resemblance. He sang almost incessantly during the half day I spent in the neighborhood, my presence seeming to inspire him to the most prodigious lyrical efforts of which he was master. Sometimes he would sit on the top of a bush or a fence-post, but his favorite perches were several ridges of sand and gravel. His flight was the picture of grace, and he had a habit of lifting his wings, now one, now the other, and often both, after the manner of the mocking-bird on a chimney-top. He and his mate did not utter a chirp, but made a great to-do by singing, and finally I discovered that all the fuss was not about a nest, but about a hulking youngster that had outgrown his kilts and looked very like a brown thrasher. Neither of this second pair of solitaires performed any evolutions in the upper air; nor did another pair that I found far up a snow-clad mountain near Breckenridge, on the other side of the Continental Divide.

The scientific status of this unique bird is interesting. He is a species of the genus Myadestes, which belongs to the family Turdidae, including the thrushes, stone-chats, and bluebirds, as well as the solitaires. He is therefore not a thrush, but is closely related to the genus Turdus, occupying the same relative position in the avi-faunal system. According to Doctor Coues the genus includes about twenty species, only one of which—the one just described—is native to the United States, the rest being found in the West Indies and Central and South America. Formerly the solitaires comprised a subfamily among the chatterers, but a later and more scientific classification places them in a genus under the head of Turdidae.



The range of Townsend's solitaire is from the plains of Colorado to the Pacific coast and north to British Columbia. According to Robert Ridgway, he has even been met with "casually" in Illinois. In Colorado many of the solitaires are permanent residents in the mountains, remaining there throughout the winter. Some of them, however, visit the plains during the fall, winter, and spring. In the winter they may be found from the lower valleys to an elevation of ten thousand feet, while they are known to breed as high as twelve thousand feet. The nests are placed on the ground among rocks, fallen branches and logs, and are loosely constructed of sticks and grass. From three to six eggs compose a set, the ground color being white, speckled with reddish brown. Doctor Coues says the birds feed on insects and berries, and are "capable of musical expression in an exalted degree." With this verdict the writer is in full accord.



CHECK-LIST OF COLORADO BIRDS

The following list includes all the species and varieties, so far as known to naturalists, occurring in the State of Colorado. Of course, these birds as families are not restricted to that State, and therefore the catalogue comprehends many of the species to be found in adjacent and even more remote parts of the country. Aside from the author's own observations, he is indebted for a large part of the matter comprised in this list to Professor Wells W. Cooke's pamphlet, entitled, "The Birds of Colorado," with the several appendixes, and to the invaluable manuals of Mr. Ridgway and Dr. Coues.

According to the latest information accessible to the writer, 389 species and varieties occur in Colorado, of which 243 are known to breed. This is a superb record, and is excelled by only two other States in the Union, namely, Texas and California. Colorado's splendid list is to be explained on the ground of its wonderful variety of climate, altitude, soil, and topographical features, such as its plains, foothills, lower mountains, and towering peaks and ranges, bringing within its boundaries many eastern, boreal, middle western, and far western forms.

The author's preference would have been to begin the roll with the most interesting birds, those to which he gave the largest share of his attention, namely, the oscines, but he has decided to follow the order and nomenclature of the Check-List of North American birds as arranged by the American Ornithologists' Union. In deference to the general reader, however, he has placed the English name of each bird first, then the scientific designation. The numbers correspond to the American Check-List. By noting those omitted, the reader will readily discover what species have not been found in Colorado.
