Clear yellow olive ; crown g'ossy blue-black; firehead, sides of head, and entire 

 nnder parts, clear yellow ; wings and tail plain, glo.seed with olive ; upper mandible dark, 

 nnder, pale; feet brown. Female and young similar; colors not so bright, the black 

 cap obscure. Small; 4f-5; wing about SJ; tail about 2. 



Habitat, the whole of North America, Mexico, and Central America. 



Not common migrant in spring; abundant in the fall. Arrives about 

 the middle of May and returns about the middle of Spptember Fre- 

 quents woodland undergrowth and willows along streams; in the fall in 

 weedy woodlands, in company with Nashville and Tennessee Warblers, 

 often in considerable flocks. Its song while with us is a low, short 

 twitter, and its note a feeble "chip." Often takes its food after the man- 

 ner of tne Vireos, hopping from twig to twig. Fall specimens have the 

 black pitch of the crown more exten^'ive and more definite than in 

 spring, and the green of upper parts deeper. Not one in ten of the birds 

 taken by me in the fall has been in the plumage of the young, as above 

 described; sometimes the black-cap is entirely wanting in the young. 



Little is known in regard to the breeding habits of the Black-cap Fly- 

 catching Warbler. It is said to breed from the latitude of Massachusetts 

 northward. The nest is composed of moss and small twigs, lined with 

 vegetable fibres. The eggs are white, sprinkled around the larger end 

 with brownish-red and lilac, and measure from .60 to .63, by from .45 to .49.
