PhiL V. 118 ( June, 1850). This species of sky lark is founded by Colonel McCall u^ on an immature bird, shot near Santa F6 in July. Captain Stans- r bury's specimen was killed near Salt Lake City, March 18, 1850, and is, consequently, an adult, in winter plumage. It differs from winter specimens of Otocoris alpestris, in having no yellow on the throat and superciliary stripe, more black on the cheeks, and less on the breast, and a very slight ferruginous tinge of the upper parts and sides of the body. The white across the forehead is more distinct. The bill is shorter, more slender, and more curved. Length.... % 6} inches. Wing 4^ " 4 Tail... ; 2} " |
