notes of complaint, but at other times, mindful of household 
cares, continue to collect insects among the bushes and lower 
limbs of the surrounding trees. I remember watching one, 
who in.fifteen minutes, during my presence, collected as many 
moths and caterpillars, continually uttering his loud chuck, 
and yet I could not find his nest, so well did he avoid indicat- 
ing its immediate whereabouts. I have known Cat-birds, in 
a like way, to sing even whilst holding in their bills a worm, 
or perhaps material for their nests, though it certainly seems 
a difficult performance. 
(d). The Canada “ Flycatchers” have a very sweet and 
agreeable song, which unfortunately is not often to be heard 
here. It is simple, like those of the other warblers, but is 
rather more pleasing than those of the Yellow Bird or Red- 
start, which it usually resembles. Their ordinary notes are a 
soft and loud chip, and a chuck, which is almost exactly like 
that of the Maryland ‘‘ Yellow-throat.” . 
(B) pusitius.24 Green Black-capped (Flycatching Warbler 
or) “Flycatcher.” (Wilson’s) “Black-cap.” — 
(A migrant through Eastern Massachusetts in spring.) 
(a). Five inches long, or less. Olive above. Bright yellow 
beneath. Crown, black; but in 9 obscure, or simply olive. 
Forehead, yellow. 
(b). The nest is built in a bush or shrub, and near the 
ground. The eggs average ‘63 X'48 of an inch, and are white, 
marked with reddish-brown at the larger end. 
(c). Dr. Brewer says that the ‘‘ Wilson’s Black-cap is found 
throughout the United States from ocean to ocean, and as far 
north as Alaska and the Arctic shores, where, however, it is 
not common.” I know no instance of these birds passing the 
%4The Hooded Warbler (M. mitratus) never, so far as I know, strays to Mas- 
sachusetts or any part of New England, though vaguely reported to do so. I have, 
therefore, omitted it. Description:—5 or more inches long. Olive above, and 
bright yellow beneath, Tail-feathers with a few white blotches. Male with head 
black, except on the sides and forehead, which are golden-yellow. The Small- 
headed Flycatcher (Muscicapa minuta) is an entirely apocryphal species.
