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]
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]
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]
The Kamilaroi/Gamilaraay and Wiradjuri people named this bird “guuguubarra”. It is native to the eastern mainland part of Australia. [10]
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.
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.[11]
Kookaburras are usually seen waiting for their prey on powerlines or low tree branches. When they see their prey they dive down and grab them with their strong beak. If the prey is small it will be eaten whole, but if the prey is larger then the kookaburra bashes it against a tree or the ground to make it softer and easier to eat.[12]
They are territorial, except for the rufous-bellied, which often live with their young from the previous season.[13] They often sing as a chorus to mark their territory.[citation needed]
They live in sclerophyll woodland and open forests, in almost any area with trees large enough to hold the nests and open patches with hunting areas. The kookaburras are declining in population because of predators, lack of prey, and the environment.
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 OlympicsinSydney. 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.[15]
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.[16][15]
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.[17]
