CERULEAN WARBLER. 



658. Dendroica caerula. 5 inches. 



Above grayish blue with black streaks, below white 

 with a bluish breast band and streaks on the sides; 

 female washed with greenish above and yellowish be- 

 low; both have white patches near the ends of the tail 

 feathers. 



These dainty little Warblers are not abundant any- 

 where, but seem to be most so in the Central States. 

 They are birds of the tree tops, rarely coming down so 

 that they can be distinctly seen. They may be more 

 common than supposed for so small a body at such 

 heights can readily be overlooked. 



Song. A little warbling trill, zee-zee-ze-ee-eep. 



Nest. In the higher outer branches of large trees 

 usually in deep woods; compactly made of dry grasses 

 and cobwebs, adorned with a few lichens; eggs white 

 specked at the large end with brownish (.65 x .50). 



Range. Interior portions of the U. S., breeding 

 north to Michigan and Minnesota; east to western 

 New York and, rarely, southern New England; win- 

 ters in northern South America.
