Band-tailed Nighthawk Nyctiprogne leucopyga

Distinctive, locally common nighthawk of lowland rivers. Appears small and dark; in dim light, best distinguished from other nighthawks by swallowlike profile and longish tail. Also note the white band across tail and lack of white in wings. Usually found near water in forest and savanna regions, occasionally in large groups; does not tend to fly high. Dark plumage recalls Blackish Nightjar, but shape and behavior are very different.
