. The birds of Illinois and Wisconsin. Birds; Birds. Jan., 1909. Birds of Illinois and Wisconsin — Cory. 325 finely pencilled with black; a broad patch of white on the wing; most of the secondaries have the outer web black, edged with white; the inner webs are grayish towards the tip; speculum, black and green; axillary plumes, white, with dark shafts. Adult female: Head and throat, whitish or buffy white, streaked and mottled with black; back, grayish brown; tertials, dusky, edged with whitish. Length, 19; wing, 10.50; tarsus, 1.60; bill, 1.40. This species is common in Illinois and Wisconsin during the mi- grations. It is barely possible a few may still breed in northern Illinois, and, according to Kumlien and Hollister, it formerly bred in Wisconsin as far south as Lake Koshkonong and still does so in the less settled portions of the state. The nest is placed on the ground and is mostly composed of feathers and down. The eggs are buffy white, 8 to 12 in number and measure about 2.15 x 1.45 inches. "A very abundant species during the migrations and not very rare summer resident." (Nelson, Birds N. E. 111., 1876, p. 140.) W. W. Cooke states it has been known to breed in Illinois.
