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

(6). The nest is built in a bush or shrub, and near the 
ground. The eggs average ‘63°48 of an inch, and are white, 
marked with reddish-brown at the larger end.

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

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-
