SLACK-POLL WARBLER. 
lighter or darker; forehead and cheeks black; a pale buff 
patch on the sides of the neck; back ash gray streaked 
with black; two white wing-bars, and a patch of white 
vn the inner vanes of the outer tail feathers near the tip; 
under parts white suffused with buff. Female with the 
crown olive green streaked with black and possibly 
chestnut; only a suggestion of chestnut on the throat 
and sides; otherwise duller in color than the male. In 
autumn male, female, and young birds almost exactly 
resemble the Black-poll Warbler, except the lighter 
green upper parts and the buff tone of the lower parts. 
Nest in evergreen-trees and situated at a Y branch from 
five to twenty feet above the ground; it is built of 
grasses and plant fibres, and lined with hairs and plant 
down. Egg white finely marked with cinnamon brown 
and olive brown mainly at the larger end. The range 
of this bird is through eastern North America north to 
Hudson’s Bay; it breeds from northern New England 
north, and winters in Central America. 
The Bay-breasted Warbler’s song is still an enigma to 
me. The only time I ever saw the handsome little fel- 
low he would not sing. Rev. J. H. Langille writes: 
**Their song, said to begin like that of the Black-poll 
and end like that of the Redstart, bears to my ear no re- 
semblance whatever to either, but is a very soft warble, 
somewhat resembling the syllables tse-chee, tse-chee, tse- 
chee, tse-chee, tse-chee, but far too liquid to admit of 
exact spelling.” Mr. Torrey thinks the song resembles 
that of the Black-poll, but says it is hardly so weak and 
formless. 
Black-poll This somewhat common bird resembles 
Warbler the Black and White Warbler in color, 
Dendroica 
ecnie ey but its markings are altogether different.
