The great potoo is a very large bird at 19-24 inches (48-60 cm) in length and weighing 12.8 oz – 1.4 lb (360-650 g). Its coloring is mottled light brown and light grey with some black thrown in and it also has large orange-yellow eyes. These bright eyes are the only way to spot this species at night as its plumage is designed perfectly for camouflage. Its call is deep and rasping growl which is repeated consistently when it decides to burst into “song”! It’s also believed to make an extremely loud bark when it’s disturbed.
