Clear yellow-olive; crown glossy blue-black; forehead, sides of head, and entire 
_ under paris, clear yellow; wings and tail plain, glossed with olive; upper mandible dark, 
under, pale; feet brown. Female and young similar; colors not so bright, the black 
: cap obscure. Small; 48-5; wing about 24; 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 September. 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 patch of the crown more extensive 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. Itis 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 .68, by from .45 to .49.
