They are found in habitats ranging from humid forest to arid savannah, as well as in suburban areas with tall trees or near running water. Though they belong to the larger group known as "kingfishers", kookaburras are not closely associated with water.[5]
Taxonomy
The genus Dacelo was introduced by English zoologist William Elford Leach in 1815.[6] The type species is the laughing kookaburra.[1] The name Dacelo is an anagram of alcedo, the Latin word for a kingfisher.[7] A molecular study published in 2017 found that the genus Dacelo, as then defined, was paraphyletic. The shovel-billed kookaburra was previously classified in the monotypic genus Clytoceyx, but was reclassified into Dacelo based on phylogenetic evidence.[2]
Classification and species
Five species of kookaburra can be found in Australia, New Guinea, and the Aru Islands:[8]
The laughing and blue-winged species are direct competitors in the area where their ranges now overlap.[9] This suggests that these two species evolved in isolation, possibly during a period when Australia and New Guinea were more distant.[citation needed]
Kookaburras are sexually dimorphic. This is noticeable in the blue-winged and the rufous-bellied, where males have blue tails and females have reddish-brown tails.
Behaviour

Kookaburras are almost exclusively carnivorous, eating mice, snakes, insects, small reptiles, and the young of other birds. Unlike many other kingfishers, they rarely eat fish, although they have been known to take goldfish from garden ponds. In zoos, they are usually fed food suitable for birds of prey.
Although most birds will accept handouts and take meat from barbecues, feeding kookaburras ground beef or pet food is not advised, because they do not include enough calcium and roughage.[10]
They are territorial, except for the rufous-bellied, which often live with their young from the previous season.[11] They often sing as a chorus to mark their territory.[citation needed]
Conservation
All kookaburra species are listed as least concern. Australian law protects native birds, including kookaburras.[12]
The distinctive sound of the laughing kookaburra's call resembles human laughter, is widely used in filmmaking and television productions, as well as certain Disney theme-park attractions, regardless of African, Asian, or South American jungle settings. Kookaburras have also appeared in several video games, including (Lineage II, Battletoads, and World of Warcraft). The children's television series Splatalot! includes an Australian character called "Kookaburra" (or "Kook"), whose costume includes decorative wings that recall the bird's plumage, and who is noted for his distinctive, high-pitched laugh. Olly the Kookaburra was one of the three mascots chosen for the 2000 Summer Olympics in Sydney. The other mascots were Millie the Echidna and Syd the Platypus. The call of a kookaburra nicknamed "Jacko" was for many years used as the morning opening theme by ABC radio stations, and for Radio Australia's overseas broadcasts.[13]
Book
The opening theme from ABC was the basis for a children's book by Brooke Nicholls titled Jacko, the Broadcasting Kookaburra — His Life and Adventures.[14][13]
In William Arden's 1969 book, The Mystery of the Laughing Shadow (one of the Three Investigators series for young readers), the laughing kookaburra is integral to the plot.[15]
In the short story (Barry Wood's "Nowhere to Go").
Film
Three newly hatched kookaburra chicks
Heard in some of the early Johnny Weissmuller films, the first occurrence was in Tarzan and the Green Goddess (1938).[16]
The dolphin call in the television series Flipper (1964-7) is a modified kookaburra call.[18]
The call is imitated perfectly by the character Billy (David Gulpilil) in the Australian film Mad Dog Morgan (1976).
The call can be heard at the beginning of Raiders of the Lost Ark (1981) in the jungle scene.
The call can be heard in the Australian film True History of the Kelly Gang (2019) when Constable Fitzpatrick is investigating the first killings by the newly formed Kelly Gang.
The overarching antagonist of Koala Man (2023) is a character named Christopher, who later takes on the identity of "The Kookaburra". Voiced by Jemaine Clement, he is the titular character's former friend turned archnemesis and often makes calls similar to the bird.
The Kookaburras are an English band from County Durham.
The lyric "... the Laughing Kookaburras call ..." appears in the song "Across the Hills of Home" on the album Something of Value by Eric Bogle.
BFD Records and BFD Productions, which are the distributors and/or copyright holders of most of the garage rock and psychedelic rock compilation albums in the Pebbles series, have the address Kookaburra, Australia.
