The subfamily Chordeilinae contains four genera and ten species. [4] Under the genus Chordeiles exists the greatest number of diversity in species in the subfamily with the lesser nighthawk (Chordeiles acutipennis), the Antillean nighthawk (Chordeiles gundlachii), the common nighthawk (Chordeiles minor), the nacunda nighthawk (Chordeiles nacunda), the least nighthawk (Chordeiles pusillus), and ...
The lesser nighthawk is a smaller bird and displays more buffy on the undertail coverts, where the common nighthawk shows white. Common nighthawks and Antillean nighthawks exhibit entirely dark on the basal portion of the primary feathers, whereas lesser nighthawks have bands of buffy spots. Common and Antillean nighthawks have a longer ...

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.
The tail is dark with white barring; the underparts are white with black bars. The adult male has a white throat; the female has a light brown throat. The most distinguishing characteristic to determine its identity from its closest relative the common nighthawk are the contrasting pale tertials near the back of the wings of a sitting bird ...
