I. Antrostomus. Bristles very conspicuous; tail rounded. 
Birds strictly nocturnal. 
II. Chordicles. Bristles short ; tail forked ; wings very long. 
(Fig. 16.) 
I. ANTROSTOMUS 
(A) vocirerus. Whippoorwill. ‘‘Night-jar.” 
(A well known summer-resident throughout New England.) 
(a). About 94 inches long. Tail rounded. 'Throat-patch, 
and tips of outer tail-feathers, in ¢ white, in @ light brown. 
Crown, black-streaked. Otherwise indescribably variegated or 
mottled with several quiet colors. The Chuck-will’s-widow (A. 
Carolinensis) of the Southern States possesses a very similar 
coloration, but is a foot long. 
(b). The eggs are laid on the ground in some dry part of 
the woods, no nest being made, unless a slight hollow be 
scratched among the fallen leaves. They are elliptical, aver- 
age 1:25 X°8d of an inch, and are creamy, spotted rather 
sparsely, chiefly with lilac and lavender. In Massachusetts, 
two eggs are laid about the first of June. 
(c). The Whippoorwills, wherever known, are well-known, 
and yet by the common people they are rarely seen. Were it 
not for their loud and famous notes, they might well be con- 
sidered by collectors very rare. As it is, they are known to 
be common at various points throughout New England, as well 
as other parts of the country ; but their distribution is probably 
irregular and local. They reach the neighborhood of Boston 
in the latter part of May, and leave it before or soon after the 
arrival of autumn. They differ from the Night ‘‘ Hawks” in 
habits very distinctly, though, according to Wilson, the two 
species were once confused even by naturalists. They are 
strictly nocturnal, unless occasionally active towards the end 
of a cloudy afternoon. During the day, they retire to some 
well shaded spot in the woods (or occasionally the ‘‘scrub”’), 
and there repose, resting on the ground, or, more often, perched 
upon alimb. Their feet are so small and weak that they never 
(?) perch crosswise, but lie along the bough. I have but
