Kookaburra larger group known as "kingfishers", kookaburras are not closely associated with water. The genus "Dacelo" was introduced by the English zoologist William Elford Leach in 1815. The type species is the laughing kookaburra. The name "Dacelo" is an anagram of "Alcedo", the Latin word for a kingfisher. A molecular study published in 2017 found that the genus "Dacelo", as currently defined, is paraphyletic. The shovel-billed kookaburra in the monotypic genus "Clytoceyx" sits within "Dacelo". Four species of kookaburra can be found in Australia, New Guinea, and the Aru Islands. Kookaburras are sexually dimorphic. This is noticeable in the blue-winged and
Blue-winged kookaburra distribution from southern New Guinea and the moister parts of northern Australia, to the vicinity of Brisbane in southern Queensland across the Top End, and as far down the Western Australian coast as the Shark Bay area. However, it does not occur between Broome and Port Hedland in northwestern Australia. Widespread and common throughout its large range, the blue-winged kookaburra is evaluated as Least Concern on the IUCN Red List of Threatened Species. Found in family groups of up to 12 individuals, it lives in open savannah woodland and "Melaleuca" swamps, as well as farmlands such as sugar cane plantations.
