But, hold! I have neglected to introduce this pretty Mozart of the West. He is known by an offensive and inapt title--the green-tailed towhee. Much more appropriately might he be called the chestnut-crowned towhee, for his cope is rich chestnut, and the crest is often held erect, making him look quite cavalier-like. It is the most conspicuous part of his toilet. His upper parts are grayish-green, becoming slightly deeper green on the tail, from which fact he derives his common name. His white throat and chin are a further diagnostic mark. The bright yellow of the edge of the wings, under coverts and axillaries is seldom seen, on account of the extreme wariness of the bird. In most of the dry and bushy places I found him at my elbow--or, rather, some distance away, but in evidence by his mellifluous song. Let me enumerate the localities in which I found my little favorite: Forty miles out on the plain among some bushes of a shallow dip; among the foothills about Colorado Springs and Manitou; on many of the open bushy slopes along the cog-road leading to Pike's Peak, but never in the dark ravines or thick timber; among the bushes just below timber-line on the southern acclivity of the peak; everywhere around the village of Buena Vista; about four miles below Leadville; and, lastly, beyond the range at Red Cliff and Glenwood.[1] [1] This list was greatly enlarged in my second trip to Colorado in 1901. The song, besides its melodious quality, is full of expression. In this respect it excels the liquid chansons of the mountain hermit thrush, which is justly celebrated as a minstrel, but which does not rehearse a well-defined theme. The towhee's song is sprightly and cheerful, wild and free, has the swing of all outdoors, and is not pitched to a minor key. It gives you the impression that a bird which sings so blithesome a strain must surely be happy in his domestic relations. Among the Rockies the black-headed grosbeak is much in evidence, and so is his cheerful, good-tempered song, which is an exact counterpart of the song of the rose-breasted grosbeak, his eastern kinsman. Neither the rose-breast nor the cardinal is to be found in Colorado, but they are replaced by the black-headed and blue grosbeaks, the former dwelling among the lower mountains, the latter occurring along the streams of the plains. Master black-head and his mate are partial to the scrub oaks for nesting sites. I found one nest with four callow bantlings in it, but, much to my grief and anger, at my next call it had been robbed of its precious treasures. A few days later, not far from the same place, a female was building a nest, and I am disposed to believe that she was the mother whose children had been kidnapped.
