ZONOTRICHIA GAMBELII, Gam b el. 
Fringilla gambelii, Nutt. Man. (I, 2d ed.) 1840, 556.— Gambel, Pr. A. N. Sc. Phila. I, 1843, 2G2. (California.) 
Zonotrichia gambelii, Gambel, J. A. N. Sc. 2d series, I, Dec. 1847, 50. 
Zonotrichia leucophrys, Newberry, Zool. Cal. & Or. Route : Rep. P.R.R, VII, iv, 1857, 87. 
Sp. Ch. — Precisely similar to Z. leucophrys, but rather smaller ; the lores are gray throughout, this color continuous with a 
white superciliary stripe along the side of the head. 
Length, 6.25 ; wing, 2.83; tail, 3.08. 
Hab. — Rocky Mountains to the Pacific coast. 
As stated in the previous article, the only appreciable and constant difference between this 
species and the preceding is found in the character of the black stripe on the side of the crown. 
In leucophrys the black passes down over the upper half of the lores, and in front of the eye, to a 
line continuous with the cutting edge of the bill, and sends back a short branch to the eye 
which cuts off the white superciliary stripe. In gambelii the superciliary stripe passes continu- 
ously forward to the ashy lores, cutting off the black from the eye. The lower edge of the black 
anteriorly is much higher than in leucophrys, and nearly on a line with the nostrils. 
The difference of size, supposed to establish this species, is hardly characteristic, but depends 
mainly on the latitude of the specimen.
