238 SINGING BIRDS. 
in New Brunswick, Quebec, and Ontario. The most southern point 
at which it has been found breeding is Chicarua, N. H., in lati- 
tude 44°, where Mr. Frank Bolles obtained a nest in 1890. The spe- 
cies ranges north to Hudson Bay, and south to Central America. 
BLACK-POLL WARBLER. 
DENDROICA STRIATA. 
Cuar. Above, grayish olive thickly streaked with black; top of head 
black; cheeks and entire under parts white; sides streaked with black; 
wing-bars and tail-patches white. Length 5% to 534 inches. 
Nest. In an evergreen forest on low branch (sometimes on the ground) ; 
of grass, roots, twigs, and lichens; lined with grass covered with white 
feathers. 
Eggs. 4-5; white, with various tints (usually pale pink or creamy), 
more or less spotted with reddish brown and lilac, — often dark brown 
and olive gray; 0.75 X 0.55. 
This rather common and well-marked species is observed to 
arrive in Pennsylvania from the South about the 2oth of April, 
but in Massachusetts hardly before the middle of May ; it re- 
turns early in September, and appears to feed wholly on insects. 
In the Middle States it is confined chiefly to the woods, where, 
in the summits of the tallest trees, it is seen in busy pursuit of 
its favorite prey. On its first arrival it keeps usually in the 
tops of the maples, darting about amidst the blossoms. As 
the woods become clothed with leaves, it may be found pretty 
generally as a summer resident ; it often also seeks the banks 
of creeks and swamps, in which situations it probably‘ passes the 
breeding season. In this vicinity the Black-poll is a familiar 
visitor in the lowest orchard-trees, where it feeds on canker- 
worms and other small caterpillars, as well as flies of different 
kinds, etc. At this time, towards the month of June, it is no 
longer a restless wanderer, but having fixed upon its station for 
the summer, it now begins, in a humble way, to display its 
musical talents in the cherished and constant company of its 
faithful mate. This note, uttered at intervals of half a minute, 
is like the sound of zsh’ tsh tsh tshé tshé, from low to high, but
