YELLOW-RUMPED WARBLER. 
This species is five inches and a half long, and eight inches 
broad ; whole back, tail-coverts, and hind head, a fine slate 
colour, streaked with black ; crown, sides of the breast, and 
rump, rich yellow ; wings and tail, black ; the former crossed 
with two bars of white, the three exterior feathers of the latter, 
spotted with white ; cheeks and front, black ; chin, line over 
and under the eye, white ; breast, light slate, streaked with 
black extending under the wings ; belly and vent, white, the 
latter spotted with black ; bill and legs, black. This is the 
spring and summer dress of the male ; that of the female of 
the same season differs but little, chiefly in the colours being 
less vivid, and not so strongly marked with a tincture of 
brownish on the back. 
In the month of October the slate colour has changed to a 
brownish olive ; the streaks of black are also considerably 
brown, and the white is stained with the same colour ; the tail- 
coverts, however, still retain their slaty hue, the yellow on the 
crown and sides of the breast becomes nearly obliterated. 
Their only note is a kind of chip, occasionally repeated ; their 
motions are quick, and one can scarcely ever observe them at 
rest. 
Though the form of the bill of this bird obliges me to 
arrange him with the Warblers, yet, in his food and all his 
motions, he is decidedly a Flycatcher. 
On again recurring to the descriptions in Pennant of the 
“ Yellow-rump Warbler,”* “ Golden-crowned Warbler, ”f 
and 66 Belted Warbler,” J I am persuaded that the whole three 
have been drawn from the present species.
