What challenges does the Oilbird face?
Like the Harpy Eagle, Golden-headed Quetzal, and Military Macaw, it is most threatened by habitat loss. Oilbirds spend their days in darkness, resting deep inside caves and sometimes within thick tree canopies.
How do birds of paradise learn to dance?
Wires ending with paddles extend from the head of the five species of Parotias, too. The birds clear a section of the forest floor before they dance. Then they spread their upper breast feathers so they resemble a tutu and perform a display called the ballerina dance.
Why do Oilbirds use echolocation?
The oilbird uses echolocation to navigate in total darkness. Oilbirds navigate, roost, and nest in dark caves. While in the cave, echolocation enables the birds to avoid colliding with others in their colony. When they leave the caves to feed at night, they are able to avoid obstacles and obstructions.

How is the oilbird adapted to its habitat?
But the oilbird’s most impressive adaptation might be its ability to maneuver within its cavern using echolocation. Unlike bats, which call at a frequency too high for human detection, Oilbirds emit a series of audible-to-humans clicks that ricochet off upcoming obstacles, providing a map of the terrain ahead.
