above, except in having 1 the throat of a dull buff colour, 
instead of pale ash ; both of these were females ; and 
I have little doubt, but they are of the same species 
with the present, as their peculiar activity seemed 
exactly similar to the males above described. 
These birds do not breed in the lower parts of 
Pennsylvania, though they probably may be found in 
summer in the alpine swamps and northern regions, in 
company with a numerous class of the same tribe that 
breed in these unfrequented solitudes.

PINE SWAMP WARBLER. 
WILSON, PLATE XLIII. FIG. IV., 
This little bird is, for the first time, described. Its 
favourite haunts are in the deepest and gloomiest 
pine and hemlock swamps of our mountainous regions, 
where every tree, trunk, and fallen log, is covered with 
a luxuriant coat of moss, that even mantles over the 
surface of the ground, and prevents the sportsman from 
avoiding a thousand holes, springs, and swamps, into 
which he is incessantly plunged. Of the nest of this 
bird I am unable to speak. 1 found it associated with 
the Blackburnian warbler, the golden-crested wren, 
ruby-crowned wren, yellow-rump, and others of that 
description, in such places as I have described, about 
the middle of May. It seemed as active in fly catching 
as in searching for other insects, darting nimbly about 
among the branches, and flirting its wings ; but I could 
not perceive that it had either note or song. I shot 
three, one male and two females. I have no doubt that 
they breed in those solitary swamps, as well as many 
other of their associates. 
The pine swamp warbler is four inches and a quarter 
long, and seven inches and a quarter in extent ; bill, 
black, not notched, but furnished with bristles ; upper 
parts, a deep green olive, with slight bluish reflections, 
particularly on the edges of the tail and on the head ; 
wings, dusky, but so broadly edged w ith olive green as
