A pack of hyenas will even drive a lion away from a carcass. Wild boars mainly eat plant food, and skunks feed on insects, mice, bird and reptile eggs, and fruit. But these nocturnal animals also feed on the flesh of any dead animals that they find. If a skunk is threatened, it stands on its front paws and squirts a jet of foul-smelling liquid at the intruder's eyes. The liquid causes burning and inflammation.
Bats spend the daytime sleeping in caves, trees or old buildings.
They sleep hanging upside-down, sometimes in huge groups of a million or more. They start to search for food soon after the sun has set. Most bats feed on insects, which they capture while in flight. Like nightjars, bats use echolocation to pin-point insects in the air. Horseshoe Bats, for example, have flaps of skin on the nose.
