ably) and Connecticut (rarely) northward to Labrador, and scuth along the 

 crest of the AUcghanies to Georgia; winters in the tropics. 



Washington, very common T. V., Apl. 25 to May 25 ; Aug. 27 to Oct. 18.

Nest, of strips of bark, fine grasses, and pine needles, lined with hairlike 

 black rootlets, in the heavier undergrowth of dense woods, usually within 

 two feet of the ground. Eggs, three to five, grayish white, with distinct and 

 obscure olive-brown markings, chiefly about the larger ends, -68 x -50. 



The male Black-throated Blue Warbler can be identified at sight, 

 but his obscurely colored mate has been the cause of many a field 

 student's neckache. When flitting about with other Warblers it is 

 difficult to observe any positive character by which to distinguish her ; 

 but the white spot at the base of the primaries is an unmistakable 

 mark, if one can see it clearly. 



When nesting, the birds seem to require woods with rather heavy 

 undergrowth. Their call-note is a sharp, recognizable chip. The 

 song of the male is generally written zwee-zwee-zwee, but both call- 

 notes and song are subject to variation.

These strong, hardy Warblers leave their cousins of the woods

 among the bayberry or myrtle {Myrioa cerifera) bushes, which bear
