BLACK-POLL WARBLER. 



661. Dendroica striata. 5 l /2 inches. 



Whole crown black; female, without black cap, green- 

 ish gray above streaked with black; young paler than 

 the female. 



These birds are one of the latest of the migrants to 

 arrive, reaching northern United States about the last 

 of May, but coming in such numbers that they are 

 found everywhere. While their plumage somewhat re- 

 sembles that of the Black and White Warbler, their 

 habits are entirely different. 



Song. A high-pitched, hissing whistle similar to 

 that of the Black and White Warbler but uttered more 

 deliberately and with an instant's pause between each 

 note. 



Nest. At low elevations in thick coniferous trees; 

 made of slender twigs, rootlets and lichens, lined with 

 hair or feathers; eggs whitish, thickly spotted with 

 brown (.75 x .52). 



Range. Eastern N. A., breeding from northern Xew 

 England, Minnesota and Wyoming north to the Arctic 

 regions ; winters south of the United States.
