Great potoo

The great potoo or grand potoo (Nyctibius grandis) is the largest potoo species and is widely distributed in Central and South America.

Much like owls, this species is nocturnal. It preys on large insects and small vertebrates, which it captures in sallies from high perches.

The great potoo is best known for its distinctive moaning growl, which echoes through the Neotropical night.

The great potoo has a large head in relation to its body, large, dark brown eyes, and a short but broad beak. Their wings are elliptical in shape, their tail is elongated, and their feathers are white, gray, black, and burgundy. The tail colors match with that of the rest of the body, with the exception of white bars that can be seen going across the tail laterally.
