CJERULEAN WARBLEE. 249 



This beautiful species is aberrant in tbe decided difference in pattern 

 of coloration and colors of the sexes, and in the sameness of colors in fall 

 and spring plumage. In some young males the olive gloss is so marked 

 as almost to constitute a green patch on the back. The white spot at 

 base of primaries is not so diagnostic as stated in the above description. 

 I have seen females in which no trace of it could be discovered on the 

 closest inspection. While with us in spring the male has a short but 

 varied song, rather a chant than a warble. 



The Black-throated Blue "Warbler has been found breeding in evergreen 

 woods in New York, and in deep woods in Connecticut. In all cases 

 the nest is placed in the fork of a bush or small tree within a few 

 inches of the ground. It is composed of grape-vine bark, rootlets and 

 Vegetable down. They measure from .70 by .50 to .61 by .47 ; they are 

 white with a " ring of brown and lilac spots and blotches around the larger 

 end, and a few minute spots of the same scattered over the entire surface," 

 often marked with a large spot of deep umber.

 ter part of July, perhaps later. They are never seen in large flocks dur-
