uttered song, which strongly suggests that of the Yellow 

 Warbler. The nest is built within a few feet of the 

 ground and the white, brown-marked eggs are laid the 

 latter part of May. 



BAY-BREASTED WARBLER 

 Dendroica castanea. Case 8, Figs. 69, 70 



The adult male is unmistakable; the female has chestnut on 

 sides and crown, a grayish streaked back and white wing-bars; 

 the young bird in the fall cannot, in the field, be certainly dis- 

 tinguished from the young Blackpoll, but has the underparts 

 tinted with buff instead of with yellow. L. sf.

The Bay-breast is one of the rarer members of its family. 

 Most of us know it only as a migrant passing northward 

 in May and southward in September, when it may be 

 found in woodlands associated with other migrating 

 Warblers. Its song resembles that of the Black and White 

 Warbler. Mrs. Farwell describes it as "a poor, weak, 

 monotonous saw-filing note." The nest has been found 

 in hemlocks 15-20 feet from the ground. The white 

 eggs, finely marked with shades of brown, are laid in 

 June. 



BLACK-POLL WARBLER 



Dendroica striata. Case 8, Figs. 71, 72 



In the spring, a black cap, white cheeks and a gray, black- 

 streaked back distinguish the male; a gray, black-streaked back, 

 the female. In the fall, young and old are olive-green, streaked 

 with black above; yellowish white below, and thus closely re- 

 sembles the young Bay-breast. L. 5 j.
