Kookaburras are known for their loud, laughter-like calls. They inhabit areas of Australia ranging from savannas to rainforests, where they can easily find food. Kookaburras eat small animals like lizards, snakes, mice and insects. They have adapted strong beaks for building nests and feet that allow them to grasp branches since they are not strong flyers. Their predators include eagles and owls, but they can puff up their feathers to appear larger if threatened. Well-known songs are associated with the kookaburra's calls from the treetops.
