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
Australia (continent) can be attributed to the continent's long geographic isolation, tectonic stability, and the effects of an unusual pattern of climate change on the soil and flora over geological time. Australia and its territories are home to around 800 species of bird; 45% of these are endemic to Australia. Predominant bird species in Australia include the Australian magpie, Australian raven, the pied currawong, crested pigeons and the laughing kookaburra.
