AUDUBON’S WOOD-WARBLER.

young of this species, at that time so much like those of the Yellow-Rump, 
were already out in small roving and busy flocks, solicitously attended and 
occasionally fed by the still watchful parents. We may notice in this 
species, as a habit, that, unlike many other birds of its tribe, it occasionally 
frequents trees, particularly the water-oaks and the lower branches of those 
gigantic firs, which attain not uncommonly a height of 2-10 feet. In the 
branches of the latter, near a cliff, opening on a prairie by the banks of 
the river Columbia, I have reason to believe that a pair of this fine species 
had a nest, as great solicitude was expressed when I several times acci- 
dentally approached the place.” 
I have given figures of the male and female, taken from specimens 
obtained by Mr. Townsend on the Columbia.

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 mar- 
gined 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 margin- 
ing 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.
