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 ; cheeks and entire under parts white ; sides streaked with black ;

 of grass, roots, twigs, and lichens; lined with grass covered with white

 turns early in September, and ajipears 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- 

 w'orms and other small caterpillars, as well as flies of different 

 kinds, etc. hx. 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,
