The '''Lesser Potoo ''' or '''Common Potoo ''' ('''''Nyctibius griseus'''''), is a nocturnal [[bird]] which breeds in tropical [[central America|Central]] and [[South America]] from [[Costa Rica]] to northern [[Argentina]] and northern [[Uruguay]]. The [[Northern Potoo]] (''N. jamaicensis'') was formerly classified as a [[subspecies]] of this species.

This [[potoo]] is a large [[near passerine]] [[bird]] related to the [[nightjar]]s and [[frogmouth]]s, but like other potoos it lacks the bristles around the mouth found in the true nightjars. It is 33-38cm long and pale greyish to brown, finely patterned with black and buff, [[camouflage]]d to look like a log; this is a safety measure to help protect it from predators, but its ''mode of perch'' is also a camouflage. It has large orange eyes.

The Lesser Potoo can be located at night by the reflection of light from its eyes as it sits on a post, or by its haunting melancholic song, a ''BO-OU, BO-ou, bo-ou, bo-ou, bo-ou, bo-ou, bo-ou, bo-ou'' dropping in both pitch and volume.
The Lesser Potoo is a resident breeder in open woodlands and savannah. It avoids cooler montane regions, rarely occurring over 1,900 meters [[Above mean sea level|ASL]] even in the hottest parts of its range (Cuervo ''et al.'' 2003). The single lilac-spotted white egg is laid directly in a depression in a tree limb.

The Lesser Potoo or Common Potoo (Nyctibius griseus), is a nocturnal bird which breeds in tropical Central and South America from Costa Rica to northern Argentina and northern Uruguay. The Northern Potoo (N. jamaicensis) was formerly classified as a subspecies of this species.

This potoo is a large near passerine bird related to the nightjars and frogmouths, but like other potoos it lacks the bristles around the mouth found in the true nightjars. It is 33-38cm long and pale greyish to brown, finely patterned with black and buff, camouflaged to look like a log; this is a safety measure to help protect it from predators, but its mode of perch is also a camouflage. It has large orange eyes.

The Lesser Potoo can be located at night by the reflection of light from its eyes as it sits on a post, or by its haunting melancholic song, a BO-OU, BO-ou, bo-ou, bo-ou, bo-ou, bo-ou, bo-ou, bo-ou dropping in both pitch and volume.

It is a resident breeder in open woodlands and savannah. It avoids cooler montane regions, rarely occurring over 1,900 meters ASL even in the hottest parts of its range[1]. Also, arid regions are usually avoided; for example in the dry Caribbean plain of Colombia the species was first recorded in April 1999[2].

This nocturnal insectivore hunts from a perch like a shrike or flycatcher. During the day it perches upright on a tree stump, and is completely invisible, looking like part of the stump because it stays so completely still as it perches.

The single[citation needed] egg is white with lilac spots[citation needed]. It laid directly in a depression in a tree limb[3], usually some meters above ground. It is not clear whether there can be, on occasion, two eggs in a clutch.[4]
