Oilbird

The Oilbird (Steatornis caripensis), also known as Guácharo, is a bird found in the northern areas of South America (including the island of Trinidad in the Republic of Trinidad and Tobago). They are nocturnal feeders on the fruits of the Oil Palm and tropical laurels, and are the only nocturnal fruit eating birds in the world. They forage at night, navigating by echolocation in the same way as bats, but with a high-pitched clicking sound audible to humans.
