CERULEAN WARBLER. 407 



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 

 7^. Above a rich dark-green oUve, 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. Leo-s flesh- 

 colored. Iris hazel. — The plumage of the female is similar to that 

 of the male.
