90 AMERICAN ORXITHOLOGY. 



DESCRIPTION. 



Length 5.5 inches. Adults in spring and summer may readily be 

 identified by the chestnut crown, throat and broad strip on the sides, 

 the female differing from the male in being marked less conspicuously; 

 young birds and winter adults are greenish gray above with black 

 streaks on the back, grayish buff below and usually have a trace of 

 chestnut on the flanks. 



NESTING HABITS. 



Nests of these Warblers are usually found in swampy woods at ele- 

 vations of from ten to twenty feet. The usual location is in the crotch 

 of some coniferous tree. The nests are made of fibres and grasses 

 closely woven and lined with fine rootlets or shreds of bark. The four 

 eggs are white, with a bluish tinge, spotted and blotched about the 

 large end with brown and stone gray. 



HABITS. 



While these birds at times are abundant, as much is not known of 

 their habits as might be desired because of the uncertainty of their ap- 

 pearance. I have not seen them in Worcester County since 1896 when 

 there was a large flight of them, lasting several days. While indi- 

 viduals probably pass through here every year they do not appear in 

 suflficient numbers to attract notice. I have always met them along the 

 banks of streams or ponds usually at low elevation. Their notes are 

 slight in volume but have good quality and are similar to those of any 

 of the others of the family.

RANGE. 



The breeding range of the Rlack-poll Warbler is in Canada north to 

 the limit of tree growth and in mountains of northern New England, 

 New York and Michigan. Their migration route lies chiefly east of 

 the Rocky Mountains and their winter home is in northern South 

 America.
