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
Rufous-bellied kookaburra fight intruders violently. Like their larger relatives, rufous-bellied kookaburras breed in termite mounds. Breeding usually takes place from May to October, though the young do not disperse fully until February and pairs have never been known to attempt a second brood in one year. Two white eggs are laid, though the actual incubation period is not known. Rufous-bellied kookaburra The rufous-bellied kookaburra ("Dacelo gaudichaud"), originally known as Gaudichaud’s kookaburra after the French botanist Charles Gaudichaud-Beaupré, is a species of kookaburra which is widely distributed through the forests of lowland New Guinea. It has also been recorded on Saibai Island, Queensland,
