GENUS II. SYLVICOLA, Swainson. WOOD-WARBLER.

Bill short, straight, rather strong, tapering, scarcely broader than

high at the base, compressed toward the end; upper mandible with its

dorsal outline declinate and nearly straight, the tip slightly

declinate, the edges overlapping, with a slight notch; lower mandible

with the angle short and rounded, the dorsal line straight, the sides

convex, the edges a little inclinate, the tip narrow. Nostrils basal,

oval or oblong, partially concealed by the feathers. Head of ordinary

size; neck short; body rather slender. Feet of ordinary length, rather

slender; tarsus longer than the middle toe, much compressed, covered

anteriorly with seven scutella, very sharp behind; toes of moderate

length, slender, free, the outer united as far as the second joint,

the hind toe proportionally large; claws moderate, well arched, much

compressed, laterally grooved, very acute. Plumage soft and blended.

Bristles at the base of the upper mandible feeble. Wings rather long,

Second quill longest, third scarcely shorter, first longer than

fourth; tail slightly emarginate. Male with the upper parts deep

ash-grey, streaked with black; crown, rump, and a patch on the sides

of the body, rich yellow: secondary coverts, and first row of small

coverts tipped with white, which forms two bars on the wing; quills

dark brown, margined with light greyish-brown; tail feathers

brownish-black, margined with ash-grey, the outer three on each side

with a white patch on the inner web near the end; a slender white line

over the eye; feathers of the eyelids white; lore and cheek black;

throat white; lower neck, fore part of breast and sides variegated

with black, the tips of the feathers being white; the rest of the

lower parts white. Female without the yellow spot on the crown,

although the feathers there are tinged with that colour at the base;

the upper parts tinged with light brown, the yellow spots on the sides

and rump paler.

_Male_, 5-1/4, 8-1/2.

From Texas northward, and throughout the interior. Extremely common.

77. 2. Sylvicola Auduboni, Townsend. Audubon's

Wood-Warbler,--Audubon's Warbler.

Plate CCCXCV. Fig. 1. Male. Fig. 2. Female.

Outer four quills nearly equal, second longest; tail slightly

emarginate. Male with the upper parts bluish ash-grey, streaked with

black; crown, rump, upper part of throat, and a patch on the sides of

the body, rich yellow; first row of small coverts largely tipped, and

secondary coverts broadly margined and tipped with white, which thus

forms a conspicuous patch on the wing; quills and tail brownish-black,

narrowly margined with greyish-white; a patch of white on the inner

webs of all the tail-feathers, but on the central reduced to a mere

edging; a small white spot on each of the eyelids; loral space and

cheek black; lower part of neck anteriorly, fore part of breast, and

sides, variegated with black and white or ash-grey, the latter colours

margining the feathers; the rest of the lower parts white. Female

without the yellow spot on the crown, although the feathers there are

tinged with that colour at the base; upper parts light brownish-grey,

streaked with dusky; lower parts whitish, tinged with brown, and

streaked with dusky; throat and rump yellow, but of a lighter tint

than in the male, and but slight indications of the yellow patch on

the sides; there is much less white on the wings, and the white

patches on the tail-feathers are of less extent.

In size, form, and proportion, this species and _Sylvicola coronata_

are almost precisely similar; and their colours are almost exactly

alike, the only remarkable difference in this respect being, that the

throat of the present species is yellow, while that of the former is

white.

_Male_, 5-3/4, wing, 3-1/12.

Columbia River, northward. Common. Migratory.
