Meet the Oilbird A Bird that Thinks its a Bat

The video explores the unique characteristics of oil birds, which resemble bats due to convergent evolution. These birds live in large colonies in caves, use echolocation, and have exceptional night vision due to a high density of rods in their retinas. Their nests are made from fruit and feces. The name 'oil bird' comes from their diet of oil palm fruit, which makes them plump. Indigenous people once used their fat as fuel. The video suggests a rebranding to 'bat birds' due to their bat-like traits.
