Birds of the Rockies

by Leander S. Keyser

Pipits
"Te-cheer! Te-cheer!"

"Te-cheer! te-cheer! te-cheer!" (accent strong on the second syllable) the birds exclaimed in half-petulant remonstrance at my intrusion as I hobbled about over the rocks. Presently one of them darted up into the air; up, up, up, he swung in a series of oblique leaps and circles, this way and that, until he became a mere speck in the sky, and then disappeared from sight in the cerulean depths beyond. All the while I could hear his emphatic and rapidly repeated call, "Te-cheer! te-cheer!" sifting down out of the blue canopy. How long he remained aloft in "his watch-tower in the skies" I do not know, for one cannot well count minutes in such exciting circumstances, but it seemed a long time. By and by the call appeared to be coming nearer, and the little aeronaut swept down with a swiftness that made my blood tingle, and alighted on a rock as lightly as a snowflake. Afterwards a number of other pipits performed the same aerial exploit. It was wonderful to see them rise several hundred feet into the rarefied atmosphere over an abyss so deep that it has been named the "Bottomless Pit."

Pipits
"Up over the
Bottomless Pit"

The pipits frequently flitted from rock to rock, teetering their slender bodies like sandpipers, and chirping their disapproval of my presence. They furnished some evidence of having begun the work of nest construction, although no nests were found, as it was doubtless still too early in the season. In some respects the pipits are extremely interesting, for, while many of them breed in remote northern latitudes, others select the loftiest summits of the Rockies for summer homes, where they rear their broods and scour the alpine heights in search of food. The following interesting facts relative to them in this alpine country are gleaned from Professor Cooke's pamphlet on "The Birds of Colorado":

In migration they are common throughout the State, but breed only on the loftiest mountains. They arrive on the plains from the South about the last of April, tarry for nearly a month, then hie to the upper mountain parks, stopping there to spend the month of May. By the first of June they have ascended above timber-line to their summer home amid the treeless slopes and acclivities. Laying begins early in July, as soon as the first grass is started. Most of the nests are to be found at an elevation of twelve thousand to thirteen thousand feet, the lowest known being one on Mount Audubon, discovered on the third of July with fresh eggs. During the breeding season these birds never descend below timber-line. The young birds having left the nest, in August both old and young gather in flocks and range over the bald mountain peaks in quest of such dainties as are to the pipit taste. Some of them remain above timber-line until October although most of them have by that time gone down into the upper parks of the mountains. During this month they descend to the plains, and in November return to their winter residence in the South.

While watching the pipits, I had another surprise. On a small, grassy area amid the rocks, about a hundred feet below the summit, a white-crowned sparrow was hopping about on the ground, now leaping upon a large stone, now creeping into an open space under the rocks, all the while picking up some kind of seed or nut or insect. It was very confiding, coming close to me, but vouchsafing neither song nor chirp. Farther on I shall have more to say about these tuneful birds, but at this point it is interesting to observe that they breed abundantly among the mountains at a height of from eight thousand to eleven thousand feet, while the highest nest known to explorers was twelve thousand five hundred feet above the sea. One of Colorado's bird men has noted the curious fact that they change their location between the first and second broods—that is, in a certain park at an elevation of eight thousand feet they breed abundantly in June, and then most of them leave that region and become numerous among the stunted bushes above timber-line, where they raise a second brood. It only remains to be proved that the birds in both localities are the same individuals, which is probable.
