The laughing kookaburra, a bird in the kingfisher subfamily, is native to eastern mainland Australia but was introduced to Western Australia in the late 19th century to control snake numbers. While it succeeded in this task, it also preyed on other native species, threatening their numbers. The kookaburra is classified as fauna under the Biodiversity Conservation Act 2016, which means people must not take or disturb them without lawful authority. However, the bird's status in Western Australia has sparked debate, with some suggesting that its population should be controlled through culling to protect native species.

What You'll Learn
Kookaburras are not native to Western Australia
The kookaburra is a bird in the kingfisher subfamily Halcyoninae. It is native to the eastern mainland of Australia, where it occupies dry eucalypt forests, woodlands, city parks, and gardens. The kookaburra is a large, robust kingfisher with a whitish head and a brown eye stripe. Its upper parts are mostly dark brown, but it has a mottled light-blue patch on the wing coverts. The underparts are cream-white, and the tail is barred with black and rufous. The male and female birds have similar plumage, but they are sexually dimorphic, with males having blue tails and females reddish-brown tails.
The introduction of kookaburras to Western Australia was primarily driven by the desire to control snake numbers. However, the impact of their introduction extended beyond snake control. Kookaburras preyed upon native species, threatening their populations. They also competed with native species for resources and nesting sites, further impacting the local bird populations.
The kookaburra has a distinctive call that resembles human laughter. This call has been widely used in media and entertainment, including films, television productions, and video games. The bird has become an iconic symbol in Australian culture, featuring on the Australian twenty-dollar note and inspiring a famous children's song, "Kookaburra Sits in the Old Gum Tree."

They were introduced to control snake numbers
The Laughing Kookaburra (Dacelo novaeguineae) is a large, carnivorous kingfisher with a distinctive laugh for a call. It is native to eastern mainland Australia but was introduced to Western Australia in the late 19th and early 20th centuries to control snake numbers.
Kookaburras are well-known for eating snakes, making the bush a safer place by keeping their numbers under control. They are large birds with large beaks, and they hunt using the 'perch and pounce' method. They watch their prey from a branch, then flutter down to seize it from among the leaf litter. Snakes are grabbed from behind the head and sometimes dropped from a great height to kill them from the impact with the ground.
Kookaburras were introduced to Western Australia as early as 1883, with birds noted between Perth and Fremantle, and in Mullewa around 1896. In 1897, the Acclimatization Society (or Animal and Bird Acclimatization Committee of WA) imported and released hundreds of birds, mainly through Ernest Le Souef, an enthusiastic supporter of the bird. By 1912, breeding populations had been established in several areas.
The introduction of the Laughing Kookaburra to Western Australia was successful in controlling snake numbers. However, it also had unintended consequences for local ecosystems. The birds preyed on native lizards, frogs, small mammals, and birds, as well as domestic fowl. They invaded the nests of smaller birds and competed with native species for nesting sites, threatening their numbers.

They are classified as fauna under the Biodiversity Conservation Act 2016
The kookaburra, a terrestrial tree kingfisher, is native to Australia and New Guinea. There are five species of kookaburra, the most well-known being the laughing kookaburra, which is native to eastern mainland Australia. The laughing kookaburra was introduced to parts of New Zealand, Tasmania, and Western Australia in the late 19th and early 20th centuries.
The laughing kookaburra was first introduced to Western Australia in 1883, with birds noted between Perth and Fremantle, and in Mullewa by 1896. The Acclimatization Society imported and released hundreds of birds between 1897 and 1912. By 1912, breeding populations had been established in several areas. The present range in Western Australia is southwest of a line joining Geraldton on the west coast and Hopetoun on the south coast.
The kookaburra is a predator and sits at the top of the food chain. Its diet consists of mice, snakes, insects, small reptiles, and the young of other birds. The introduction of the kookaburra to Western Australia has had a devastating impact on native fauna. They prey on native species, threatening their numbers. This has raised questions about whether kookaburras should be culled to protect native wildlife.
Despite the environmental concerns, kookaburras are classified as fauna under the Biodiversity Conservation Act 2016 in Western Australia. This means that people must not take or disturb them without lawful authority. The protection afforded to kookaburras under this legislation ensures their presence in the state, even as discussions continue about the potential need for culling in certain areas.

They are predators and sit at the top of the food chain
The laughing kookaburra, native to eastern mainland Australia, was introduced to Western Australia as early as 1883 to control snake numbers. It has a robust body, a large head, and brownish-white plumage. Its head is mostly white, with a dark eye stripe. It is a member of the kingfisher subfamily Halcyoninae and is considered a predator.
Kookaburras are aggressive predators that can deftly swoop down to catch their prey. They are known to feed on insects, worms, and crustaceans and sometimes on small snakes, mammals, frogs, and birds. They have a sturdy beak that is perfectly designed for capturing and devouring prey. They are also capable of bashing larger prey against the ground or a tree branch to kill and soften it before eating.
Kookaburras are territorial birds and will engage in fights with other birds of the same species to establish dominance and defend their territory. They are not known to be aggressive towards humans, but they can exhibit aggressive behaviour towards other birds and animals when defending their territory or food source. They live in family groups called "kookaburra clans", consisting of a breeding pair and their offspring from several breeding seasons.
Kookaburras are apex predators in their ecosystem. They are skilled hunters with strong beaks and agile movements, allowing them to capture a variety of prey. Their ability to swoop down from a height gives them a significant advantage in hunting. While they do have some natural predators, such as eagles, owls, snakes, and feral cats, their position at the top of the food chain is secured by their adaptability and hunting prowess.
The laughing kookaburra is a well-loved bird in Australia and is easily recognised by its distinctive laugh-like call. It has been featured on Australian stamps and coins and was one of the mascots for the 2000 Summer Olympics in Sydney. Its unique call is often used as a stock sound effect in media productions set in jungle or Australian bush environments.

Their distinctive call is widely used as a stock sound effect
The laughing kookaburra, a bird native to eastern mainland Australia, produces a distinctive call that is often used as a stock sound effect in media. This bird was introduced to Western Australia in 1897 to control snake numbers. However, it also preyed on other native species, impacting their populations.
The kookaburra's call, described as a "cackling laugh", is frequently used in films, cartoons, and TV series that depict jungle environments. This sound effect is so common that it has become a trope, with viewers associating it with mysterious adventures in impenetrable jungles. The use of the kookaburra's call in media is not always accurate, as the bird is only found in northern Australia, the east coast of Australia, New Guinea, and the islands between these regions.
The distinctive call of the kookaburra is often delivered by several birds simultaneously and has been transcribed in various ways, including "OOOOOO-HOOO-OOO-HOO-HOO-AHAHAHAHA" and "who-who-who-ah-ah-ah-ah-HA-HA". This call is so well-known that it has been described as "obligatory" in jungle scenes.
While the kookaburra's call is commonly used as a stock sound effect, it is also available as a downloadable sound effect for use in videos, games, podcasts, and other applications. These sound effects can be generated by providing a detailed description, with some providers allowing users to specify the duration of the effect.
The kookaburra's call has been featured in various media, including the unreleased game Tattoo Assassins, Duck Amuck, Goofy cartoons, Jumanji: The Next Level, and Looney Tunes: Back in Action. In some cases, the use of the sound effect is appropriate given the location, such as in Taz-Mania and Moonbird, while in others, it is inaccurate, as in The Leech Woman and Looney Tunes: Back in Action, where it is used to depict African jungles.
