Spinus pinus.
Descriptions of First Plumage of Certain North Am, Bbs. Wm. Brewster.
57. Chrysomitrís pinus.
First plumage: female. Strong mustard-yellow, tinged on the upper parts with brownish-olive, every feather, excepting those on the abdomen, streaked with dark brown. Wing-bands and outer edging of secondaries fulvous. From a specimen in my collection, shot at Upton, Me., August 18, 1873. The first plumage of this species is certainly most remarkable. The yellow is by no means a mere wash or tinge of color, but pure, strong, and uniformly distributed. In a series of five or six specimens collected at about the same time, several exhibit a brownish cast, especially on the upper parts, while scarcely any two agree as to the relative amount and color of the dusky streaks. In one example they are very broad and almost black, in another, tear-shaped and of a dull brown.
