The genus Lurocalis contains the chestnut-banded nighthawk (Lurocalis nattereri), the Rufous-bellied nighthawk (Lurocalis rufiventris), and the short-tailed nighthawk (Lurocalis semitorquatus). [4] There is only one species in the monotypic genus Nyctiprogne which is the band-tailed nighthawk ( Nyctiprogne leucopyga ), a small bird ...
The nighthawks are confined to the New World, and the eared nightjars to Asia and Australia. [8] A number of species undertake migrations, although the secretive nature of the family may account for the incomplete understanding of their migratory habits. Species that live in the far north, such as the European nightjar or the common nighthawk ...
The lesser nighthawk (Chordeiles acutipennis) is a nightjar found throughout a large part of the Americas. This bird looks similar to the common nighthawk but is slightly smaller, has a slightly less deeply forked tail, and is more buffy in coloration. Their distinctive mouths are very well adapted for capturing insects mid-flight.
The U.S. population of nighthawks has declined by about 2% per year between 1966 and 2014, amounting to a cumulative decline of 61%, according to the North American Breeding Bird Survey.

Strisores (/ s t r aɪ ˈ s oʊ r iː z / stry-SOH-reez [3]), sometimes called nightbirds, is a clade of birds that includes the living families and orders Caprimulgidae (nightjars, nighthawks and allies), Nyctibiidae (potoos), Steatornithidae (), Podargidae (), Apodiformes (swifts and hummingbirds), as well as the Aegotheliformes (owlet-nightjars) whose distinctness was only recently realized.
Six specimens of nacunda nighthawk were found to average 159 g (5.6 oz) in body mass, with range of 130 to 188 g (4.6 to 6.6 oz). [5] Its very large size, large head, and pale body with highly contrasting black primaries make the nacunda nighthawk easy to identify. [6] This species is noteworthy for its partially diurnal habits.
