The oilbird has an unfortunate name, because there’s nothing oily about them. They’re actually quite pretty, with shade of brown and diamond-shaped white spots along their bodies. They eat mostly fruit, which is pretty normal for birds, but the oilbird is actually nocturnal, meaning that they find their food at night. And because it’s dark out, they use echolocation to find their food. A strange thing to do when their food doesn’t even move. The reason that they’re called the oilbird is because they eat the fruit of the oil palm, and were unfortunately hunted and killed in order to extract the oil from their bodies.
