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 emargi- 
nate. 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 se- 
condary 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 in- 
ner 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 mar- 
gining the feathers ; the rest of the lower parts white. Female with- 
out 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 Sijlvicola coronata are 
almost precisely similar ; and their colours are almost exactly alike, 
the onlj^ remarkable difference in this respect being, that the throat of 
the present species is yellow, while that of the former is white.
