Description
Within the finch family, the Gray-crowned Rosy Finch is medium-large with a comparatively long notched tail and wing. Adults are brown on the back and breast and mainly pink on the rest of the underparts and the wings. The forehead and throat are black; the back of the head is grey. They have short black legs and a long forked tail. There is some variability in the amount of grey on the head. Adult females and juveniles are similar. Overall length is 140–160 mm (5.5–6.3 in), wingspan 33 mm (1.3 in), and weight 22–26 g (0.78–0.92 oz). L. t. wallowa has an almost entirely gray head. The Pribilof and Aleutian subspecies have a length of 170–210 mm (6.7–8.3 in) and weight of 42–60 g (1.5–2.1 oz), about twice the size of the other subspecies. The Black Rosy Finch has a black instead of brown body and the Brown-capped Rosy Finch is a lighter brown and lacks the gray face patch.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
