SWALLOW TRIBE. 
NIGHT-HAWKS. (Caprimulgus. X.) 
With the bill extremely short, feeble, and cleft beyond the eyes; 
upper mandible almost always surrounded with spreading bristles, 
and somewhat hooked at the tip, the margin turned outward. Nos- 
trils basal, wide, partly closed by a feathered membrane, and leav- 
ing usually a tubular opening. Tongue small, acute, and entire. 
Feet , tarsi partly feathered, the anterior toes united by a small mem- 
brane to the 1st articulation; the hind toe reversible. Nails very 
short, beneath channeled. Wings long, the 1st primary shorter than 
the 2d and 3d, which are longest. Tail of 10 feathess. — Female 
easily distinguishable from the male ; but the young similar with the 
adult. They moult once or twice in the year ; and the plumage is of 
dull and very blended colors. 
These are solitary, shy, and sylvan birds, flying rapidly in the 
twilight and night, when their vision is more acute. Except in 
cloudy weather, they remain concealed by day, like Owls ; and in 
consequence of the softness of their feathers, their flight is nearly si- 
lent. They hunt for moths with the mouth extended open. They 
remain constantly paired, and in the breeding season flutter their 
wings like Pigeons. They lay one or two large eggs on the ground, 
without nest, and rarely in a hollow tree, or in the cleft of a rock. 
The voice is unpleasant, quaint, and monotonous. They sometimes 
also utter a booming sound in flight, usually at the moment of rapidly 
descending in their aerial gyrations. They inhabit all parts of the 
globe, but abound in the warmer parts of America.
