Band-tailed Nighthawk Nyctiprogne leucopyga

Band-tailed Nighthawk is a small, dark nightjar of forest and savanna, generally near water. It occurs through much of northern South America east of the Andes, from Venezuela south to Bolivia and central Brazil. The song is frog-like and might be overlooked. The band in the tail is inconspicuous, although it sometimes is visible in actively feeding birds at dawn or dusk. More often, this species simply appears all dark as it flies in an erratic, bat-like flight, sometimes in rather large groups. Like other caprimulgids, Band-tailed Nighthawk feeds on aerial arthropods, although it sometimes takes prey directly from vegetation.
