Kookaburras, known as the Laughing Jackasses of Australia, are from the family, Kingfishers. They are to be found in the woodland areas of eastern Australia. Australians value the Kookaburra, not only as an intriguing member of the strange fauna, but for its habit of feeding on snakes and lizards. Less welcome is the Kookaburra's fondness for the young of other birds, and its occasional raids on farmyards for ducklings and baby chicks. Kookaburras generally live in pairs or in small groups in open woodland. They incubate their two to four pure white eggs in hollow tree trunks, tree holes, or in excavated termite nests. Both adults incubate for a period of 25 days. The young leave the nest 30 days after hatching, but the parents continue to feed them for another 40 days.
