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
Laughing kookaburra and in partly cleared areas or farmland with trees along roads and fences. In urban areas it is found in parks and gardens. The range of the laughing kookaburra overlaps with that of the blue-winged kookaburra in an area of eastern Queensland that extends from the Cape York Peninsula south to near Brisbane. Around Cooktown the laughing kookaburra tends to favour areas near water while the blue-winged kookaburra keeps to drier habitats. Kookaburras occupy woodland territories (including forests) in loose family groups, and their laughter serves the same purpose as a great many other bird calls—to mark territorial borders. Most
