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

It is one of four members of the genus "Dacelo" which are commonly known as kookaburras. Alternative common names include barking or howling jackass, or Leach's kookaburra. The number of subspecies is unclear - with four recognised by most authorities, although others have proposed the three Australian subspecies gradually change across Australia and should be treated as one. The adult blue-winged kookaburra measures around in length and weighs 260 to 330 g. Compared to the related laughing kookaburra, it
