males noticed as we passed along were out of all proportion, in numbers, to the females seen. They were very heedless of approach, and any number could have been readily destroyed. I never saw any at Fort Whipple, or elsewhere in Arizona, though Dr. Heermann says that they are abundant in the southern portions of the Territory, and specimens are recorded from Lower California.” Mr. Allen found the Lark Bunting one of the few birds that seemed strictly confined to the arid plains near Fort Hays, in Kansas. He met with it in great abundance, but only on the high ridges and dry plateaus, where they seemed to live in colonies. He describes them as very wary, and very tenacious of life, often flying long distances, even after having been mortally wounded. They seemed to delight to fly in strong winds, when most other birds kept in shelter. They sing while on the wing, hovering in the wind and shaking the tail and legs after the well-known manner of the Yellow-breasted Chat. Its song seemed to him to strongly resemble that of the Chat, with which, at such times, its whole demeanor strikingly accorded. Dr. Heermann, in his Report on the birds collected in the survey on the 32d parallel, states that he first observed these birds on approaching the Pimos villages. They were associated with large flocks of Sparrows, gleaning grain and grass-seed upon the ground. When started up they flew but a short distance before they resumed their occupation. After crossing the San Pedro he again found them in large flocks. At Fort Fillmore, in Mesilla Valley, it was also quite common and associated with the Cowbird and Blackbird, searching for grain among the stable offals. He again met with them in Texas, in the month of April, most of them still retaining their winter coat. He describes the tremulous fluttering motion of the wings with which the male accompanies its song while on the wing as very much after the manner of the Bobolink, and he speaks of their song as a disconnected but not an unmusical chant. He found their nests on the ground, made of fine grasses, lined with hair, and in one instance he found the eggs spotted with faint red dashes. At Gilmer, in Wyoming Territory, their nests were found by Mr. Durkee built on the ground, and composed of dry grasses very loosely arranged. The eggs, four or five in number, are of a uniform and beautiful light shade of blue, similar to those of the _Euspiza americana_. They measure .90 by .70 of an inch, are of a rounded-oval shape, and, so far as I have observed, are entirely unspotted, although eggs with a few reddish blotches are said to have been met with.
