Our Bird Comrades

by Leander S. Keyser

The common name of the subject of this sketch is the brown-capped rosy finch; in the scientific works on ornithology he is called the brown-capped leucosticte. He is certainly a bird of peculiar habits and out-of-the-way preferences. Should he send you his card from his summer residence, it would read something like this: "At home in the mountains of Colorado, from 10,000 feet above sea-level to the summits of the highest peaks." There is only one other bird in Colorado that has so high a summer range, and that is the white-tailed ptarmigan, usually called, in hunter's parlance, the "mountain quail."

The rosy finch is slightly larger than the bluebird. His general color is light brown, suffused with a beautiful pink or rosy tint, the dark shaft lines and pale edges of the feathers of the back giving it a striped appearance. The forepart of the top of the head is blackish, and the cap is brown, from which he gets the qualifying adjective of his name. In the best nuptial plumage the rosy coloring is heightened to an intense crimson, especially on the wings, tail coverts, and the under parts. The female's attire is paler and duller of tint, the pink being sometimes almost obsolete. Oddly enough, in summer the bills of these birds are deep black, while in winter they become yellow, only the tip remaining black or blackish.

My introduction to the leucostictes occurred on the summit of Pikes Peak, at an elevation of 14,147 feet above the level of the sea. With exhausting toil I climbed the peak one night, and the next morning, when I stepped out of the signal station, where I had secured lodging, a flock of the brown-caps were flitting merrily about the garbage heap, helping themselves to an early breakfast. Their blithe chirping sounded very much like conversation all among themselves, and proclaimed two pleasant traits of character—cheerfulness and good temper. It was evident that they were happy and contented in their alpine home, in the upper story of the world, the rare, cool, exhilarating air, the majestic panoramas, and the unlimited freedom all contributing to the blithesomeness of their spirits. The keepers of the signal station told me that the birds came to the refuse pile every day for their meals.

Two years later, on the twenty-eighth of June, a friend and I clambered up Grays Peak, which is several hundred feet higher than Pikes Peak. It was a long and toilsome climb, winding about the snowbeds of the mountain side. Sometimes we scaled straight up the acclivity on "all fours," throwing ourselves down on the rocks at frequent intervals to rest our aching limbs and fill our lungs with the rarefied air; up and up and up, until at last, with a long pull and a strong pull, we stood on the sky-haunting ridge above all the surrounding elevations, looking down upon the rest of the world, which seemed to be crouching at our feet.

Long before we reached the summit we were saluted by a new bird voice—one that had not been heard farther down the mountain. It was a cordial chirp, which seemed to bid us welcome to the alpine region and to assure us that there was no risk in climbing to these sky-aspiring summits. A glance proved that our little salutarian was the brown-capped rosy finch, which I had not seen since my ascent of Pikes Peak. Down in the green, copsy valley at the base of the mountain we had met with the white-crowned sparrows and Wilson and Audubon warblers; then, as we began to climb the steep shoulder of the mountain, the American pipits had become our comrades, accompanying us about half way up the elevation; now all other birds had disappeared and we entered the arctic precincts of the leucostictes, which, like a gallant bodyguard, escorted us to the summit, cheering us on with their friendly chirping. The bailiwicks of the pipits and the rosy finches slightly overlapped, as did also those of the pipits and the white-crowned sparrows near the great mountain's base. However, no pipits ventured to the upper story of this elevated region—at least, not at the time of our visit, although they may have ascended to the summit later in the season.

How blithe and cheerful were the pretty leucostictes! Now they darted fearlessly about in the air over the summit and the gorges; now they alighted on the wall of the dilapidated old signal station, and anon hopped and flitted about over the extensive snow beds, picking up dainties that were evidently to their taste, all the while beguiling the time with their companionable, half-musical chirping. So far as I observed, they have no real song. If they have, it is strange that they did not furnish a sample of their lyrical gifts on so calm and sweet a summer day in the season of courtship.

What billsome morsels did they find on the snow? We examined their white tablecloth and found a number of small beetles and other insects creeping up through it or crawling around over its surface. Thus Nature spreads her banquet everywhere for her feathered children.

One cannot help falling into the speculative mood as one reflects on these little birds and their remarkable habits. Why do they, of all birds, choose the highest mountain peaks for their summer homes? Might the cause be physiological? Are their lungs, muscles, and nervous systems so constructed as to be adapted to a dry, rare, crisp atmosphere, which would prove injurious, perhaps fatal, to birds of a different structural organization? Who can tell? At all events, they live on these towering elevations all summer long, woo their plainly-clad mates, build their nests, and rear their happy families.

Their nests are set amid the rocks, and are quite bulky, the walls composed of grasses and the lining consisting of soft feathers. In order to procure the grasses required, they must descend at least to the belt of scant vegetation just below the region of bare rocks and boulders. Where they get the downy feathers for the carpet of their nurseries I have not been able to ascertain. No nest has yet been discovered below an elevation of 12,000 feet. Our little bird may, indeed, be called a "haunter of the sky." The height of the breeding season is in the latter part of July. The broods having left the nests, old and young gather in small flocks and range over the peaks and ridges, feeding on the insects to be found on the fields of snow.

No less interesting are the habits of these birds in winter. In October and November most of them descend only to the timber line, where they remain throughout the winter, save as they are driven down into the denser forests by the fierce tempests of this arctic region. What feathered Vikings they are! They do not even make for themselves snow huts for protection from the winter storms. However, a few descend almost to the base of the foothills, while others—perhaps the less hardy—seek a blander climate in the northern part of Mexico.
