VIREO HUTTONI, Cassin. 
Hutton’s Flycatcher. 
Vireo huttoni, Cassin, Pr. A. N. Se. Phila. V, Feb. 1851, 150,—Is. VI, pl. i, f. 1. 
Sp. Cx.—Fourth, fifth, and sixth quills about equal and longest ; third and seventh equal, and .10 of an inch shorter ; second 
quill not longer than secondaries; spurious primary large, broad, about half the second. 
Above olive green, becoming 
considerably darker towards the bill and on sides of head. 
Beneath dirty greenish white, tinged with greenish yellow 
posteriorly. A paler ring round the eye. Two broad bands across the wing coverts and edges of inner tertiaries, with greater 
portion of outer web of the outer tail feather greenish or olivaceous white. Length about 4.75 inches ; wing, 2.35. 
Hab.—South California, across by valley of Gila, to northeastern Mexico. 
The yellowish ring round the eye is very narrow. The space between the upper edge of the 
eye and the bill is yellowish, but not well defined. The rest of the sides of head and neck are 
dark olivaceous, like the back. There is no white whatever in the under parts or elsewhere, the 
lightest tints beneath being yellowish, with a brownish tinge. The sides of the body are 
olivaceous yellowish. 
This species differs from V. gilvus in its large first primary, the whitish bands and edgings of 
the wings and tail, and in the more olivaceous colors generally. It is of rather smaller size. 
It is about the same size as V. noveboracensis, but has a much more slender bill, which is horn 
color instead of blue black ; it lacks the vivid yellow on the forehead and in front of the eye; 
the head is darker; the outer tail feather paler on its outer edge. It lacks the pure white of 
the throat and the vivid contrast in color between the sulphur yellow of the sides and the 
whitish of the middle of the body. Both species have concealed whitish on the rump. It is 
larger than V, belli, although the bill is the same size; it has the sides of the head and neck 
much darker ; there is more whitish on the wing and outer tail feather ; the inferior colors are 
much browner, with less of the vivid sulphur yellow. 
The differences between the present species and the closely allied V. cassinii will be pointed 
out in the description of the latter species.
