Genus Nyctibius
Long-tailed Potoo - The core range of the Long-tailed Potoo is the contiguous region of the entire northwestern and southwestern Amazon Basin. In the north of South America, the range is in the eastern regions of Venezuela's Orinoco River drainage and the highlands bordering Guyana; in Guyana, the range extends into the eastern portions of the Essequibo River drainage to the border with Suriname. The contiguous range extends southward through Andean and Amazonian portions of Colombia, Ecuador and Peru.
Great Potoo - Though related to the nightjars, like other potoos it lacks the bristles around the mouth found in the true nightjars . Larger than a crow at 48-60 cm long and 360-650 grams , this potoo's size is distinctive when seen. It is pale greyish to brown, finely patterned with black and buff. It has large orange eyes. The overall appearance is pale and grayish. The underside is barred and vermiculated, including the buffy chest. The tail is barred with sharply defined black borders, while the head and back are mottled with gray and buff. Like most members of their order, the Great Potoo has plumage that is well-suited for camouflage.
Grey Potoo - This potoo is a large cypselomorph 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.
Northern Potoo - It is a fairly large bird with a length of 38-46 centimetres. It has a long tail, short rounded wings, large head, very short legs and a small bill with a large gape. It is most commonly seen perched motionless in an upright position on branches or posts. The plumage is grey-brown with an intricate pattern of black, grey and cream markings. The cheeks are pale with a dark malar stripe below them. The large eye has a yellow iris which can shine red in light at night. The bird's calls are hoarse and guttural.
White-winged Potoo - White-winged Potoo's natural habitat is subtropical or tropical moist lowland forests.
Andean Potoo - The Andean Potoo is a species of bird in the Nyctibiidae family. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests.
