ers with a whitish spot on the inner vanes : 2d primary much 
longer than the 6th ; tail wedge-shaped, with the feathers 
pointed. 
The most gloomy pine and hemlock swamps of the 
mountainous regions in the Middle and Northern States 
are, in the spring, the resort of this species, which, 
though not uncommon, was first described by the inde- 
fatigable Wilson. Whether they breed in those dark 
and moss-grown morasses is yet unknown. They visit 
Pennsylvania from the South about the middle of May ; 
and are occasionally seen in the thick woods of Massa- 
chusetts in the month of October. It is not known to 
have any note or song, associates with other species of 
the genus, and is an active fly-catcher, nimbly darting 
through the branches and flirting its wings as it collects 
its prey. 
The Pine-Swamp Warbler is about 5 inches in length; alar extent 
7J, Above a rich dark-green olive, with slight bluish reflections on 
the edges of the tail. Wings and tail dusky, the former widely edg- 
ed with olive. Immediately below the primary coverts there is a tri- 
angular spot on the quills of a yellowish-white where exposed, but 
enlarging, and pure white below. Tail wedge-shaped, the feathers 
very acute ; 2 or 3 of the exterior feathers obscurely spotted with 
whitish. From the nostrils over the eye extends a whitish line, with 
a touch of the same on the lower eyelid ; lores blackish. Below pale 
ochreous, less pure on the throat, and inclined to brownish on the 
sides beneath the wings. Bill black, without notch. Legs flesh- 
colored. Iris hazel. — The plumage of the female is similar to that 
of the male.
