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 with olive green as to appear wholly of that tint; 
immediately below the primary coverts, there is a single 
triangular spot of yellowish white ; no other part of the wings 
is white ; the three exterior tail-feathers, with a spot of white 
on their inner vanes ; the tail is slightly forked ; from the 
nostrils over the eye, extends a fine line of white, and the 
lower eyelid is touched with the same tint ; lores, blackish ; 
sides of the neck and auriculars, green olive ; whole lower 
parts, pale yellow ochre, with a tinge of greenish ; duskiest on 
the throat ; legs, long and flesh coloured. 
The plumage of the female differs in nothing from that of 
the male.
