In Northfield, Ill., near the lake shore, Mr. Robert Kennicott met with the nests of these birds in great abundance. From these facts I infer that it is not necessarily or exclusively a bird of the sea-shore, but that in certain favorable localities it is as abundant in the interior as on the coast, and that at intervals it may be met with from Texas to Maine, and from the Atlantic to the interior, nearly or quite to the Pacific coast.
In Jamaica, Mr. March states, this species is not uncommon in the savannas and grass lands near Spanish Town. It is a resident in that island, and breeds there in considerable numbers, nesting in tufts of grass-roots. It is only common in certain localities.
I have never heard its note to know it. Wilson speaks of it as a short, weak, interrupted chirp. According to Mr. Ridgway, it bears a close resemblance to the note of a grasshopper. Nuttall says they sing in an agreeable voice, something like that of the Purple Finch, though less vigorously; and Audubon characterizes it as an unmusical ditty, composed of a few notes weakly enunciated at intervals.
It is terrestrial in its habits, living, nesting, and feeding on or near the ground. It subsists on larvæ, insects, and the seeds of grasses and small weeds.
This bird builds its nest on the ground, usually in a small tuft of grass or in a cluster of plants. It is made of dry grasses, and is lined with fine bent and horsehair. The young are said to follow their parents for a short time, but soon separate, and learn to take care of themselves. This species is not gregarious, and is never seen in flocks, not even when just about to migrate.
Wilson and Nuttall describe the eggs as grayish-white, sprinkled with brown. Audubon says they are dingy-white, sprinkled with brown spots. This is not accurate. The ground-color is a clear crystalline white, beautifully dashed and marbled with bold markings of an almost golden brown. These spots vary in size, are often quite large, and occasionally make a corona about the larger end. The eggs are of a rounded oval, almost spherical, shape, measuring .75 by .63 of an inch.

WESTERN YELLOW-WINGED BUNTING.
Coturniculus passerinus, var. perpallidus, Ridgway, Report of U. S. Geol. Expl. 40th Par. Coturniculus passerinus, Cooper, Orn. Cal. 1, 189.
Sp. Char. Adult (No. 58,605 ♂, Antelope I., Great Salt Lake, June 4, 1869; U. S. Geol. Expl. 40th parallel) similar to var. passerinus, but the light tints above prevailing, the ground a pale ash-color, and the chestnut spots in excess of the black ones. Specks on the nape very minute. Buff tinge to cheeks, throat, and jugulum so faint as to be scarcely appreciable. Wing, 2.60; tail, 1.90; bill, .33 from frontal feathers by .24 in depth at base; tarsus, .70. Young (No. 53,942 Ruby Valley, Nev., July 22, 1868) differing from young of var. passerinus in a predominance of the light, instead of the dark, markings on upper surface, streaks across breast so faint as to be just appreciable, instead of distinct, and nearly black.
