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.
