Kookaburras are terrestrial tree kingfishers of the genus Dacelo native to Australia and New Guinea, which grow to between 28 and 47 cm in length and weigh around 300 g (11 oz). The name is a loanword from Wiradjuri guuguubarra, onomatopoeic of its call. The loud, distinctive call of the laughing kookaburra is widely used as a stock sound effect in situations that involve an Australian bush setting or tropical jungle, especially in older movies.
