Genus CAPRIMULGUS

Wing long and pointed, first primary shorter than second and generally than the third ; tail long, more or less rounded. Sexes generally distinguished by the presence of white spots on the wings and tail in males; represented by buff or rufous spots, or else wanting altogether, in females and young birds. In some species, however, the sexes are alike. Strong rictal bristles, generally white at the base. No ear-tufts.

The range is that of the family.

The habits of all Nightjars are similar. They rest usually on the ground amongst vegetation or stones during the day, and issue forth at dusk to feed. Their food consists of insects, and largely of beetles, which they capture, chiefly at all events, on the wing. Their flight is noiseless and tolerably rapid. From time to time they settle on the ground, on a stump of a tree, or a branch, or on a stone, and thence utter a peculiar rather monotonous reiterated note, which varies much in different species. When a Nightjar perches it selects a branch of considerable size, and sits as a rule longitudinally, not across like an ordinary passerine bird, and whenever it alights it rests with its whole body on the ground or perch. Besides their calls most Nightjars have a chuckling note, uttered during flight.
