The laughing kookaburra (Dacelo novaeguineae), the largest member of the Kingfisher family Halcyoninae, gets its name from its manic laughter-like call - its chuckling voice is actually a territorial call to warn other birds to stay away. It is native to the eucalyptus forests of eastern Australia. The upperparts are mostly dark brown but there is a mottled light-blue patch on the wing coverts. Its beak can reach four inches long and is used to snatch a variety of invertebrates and small vertebrates, including the occasional small snake.
