CERULEAN WARBLER. 
658. Dendroica cxrulea. 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.—lInterior portions of the U. S., breeding 
north to Michigan and Minnesota; east to western New 
York and, rarely, southern New England; winters in 
northern South America.
