Swallow-tailed Nightjar Uropsalis segmentata Scientific name definitions

The spectacular long tail of male Swallow-tailed Nightjar, along with its cloud forest habitat, makes it a much sought-after species in the Andes from Colombia south to Bolivia. Its buzzy, whistled rising-falling song is distinctive, although it may be confused with the song of Wattled Guan (Aburria aburri); both of these species often sing at dusk or after dark, but the nightjar's song is much weaker and more level than the guan's. The long, bifurcated tail of male Swallow-tailed Nightjar is distinctive, but the female is best identified by her dark plumage, uniformly mottled with warm cinnamon brown.
