Great Potoo

About

The great potoo is a master of disguise, widely distributed in Central and South America. Its most well known characteristic is its unique moaning growl that it vocalizes throughout the night, creating an unsettling atmosphere. It is nocturnal and spends its days perfectly camouflaged against tree branches or tree stumps, staying completely still and blending in with its bark-like plumage.

It preys on large insects and small vertebrates, which it captures in sallies from high perches at night. Its huge, yellow eyes provide excellent night vision, but what’s really remarkable is its ability to keep them almost closed during the day while still maintaining enough of a slit to watch for predators.
