Family Mniotiltidce Chestnut-sided Warbler 7 5 . 



28. CHESTNUT-SIDED WARBLER 



{Dendroica pensylvanica . ) 



Upper parts streaked with black and pale yellow or whitish ; 

 crown clear yellow, bordered on each side with black which 

 extends down into a small patch in front of the eye ; under 

 parts in general white, but the sides of a rich reddish brown ; 

 wings and tail dusky, tail with white blotches, wings with two 

 white bars which are more or less confluent. Beak slender, 

 dark ; feet brown. Bird about two-thirds the size of a sparrow. 

 Sexes similar, save that the female is duller, and may want the 

 black markings on the head. 



THE chestnut-sided warbler is a summer resident, 

 coming to us early in May, and leaving us in Sep- 

 tember. During migration they may be found in 

 open mixed woods and thickets ; for the summer 

 they retire to moist woodlands and swampy thick- 

 ets. They are most likely to be met at the time of 

 the spring migration. 



The nest is placed in the fork of a bush or small 

 tree ; and the eggs are laid about the first of June. 



The song is simple ; one variation is almost 

 exactly like the song of the yellow warbler. An- 

 other consists of half a dozen notes each higher 

 than the preceding, except in the case of the last, 

 which is lower than the one preceding it.
