The blue-winged kookaburra (Dacelo leachii) is a large species of kingfisher native to northern Australia and southern New Guinea.
Measuring around 40 cm (16 in), it is slightly smaller than the more familiar laughing kookaburra. It has cream-coloured upper- and underparts barred with brownish markings. It has blue wings and brown shoulders and blue rump. It is sexually dimorphic, with a blue tail in the male, and a rufous tail with blackish bars in the female.
The blue-winged kookaburra was first collected by Sir Joseph Banks in 1770, but was initially overlooked and confused with the laughing kookaburra, and was finally officially described by Nicholas Aylward Vigors and Thomas Horsfield in 1826, its specific name commemorating British zoologist William Elford Leach. [2] It is one of four members of the genus Dacelo which are commonly known as kookaburras. Alternative common names include barking or howling jackass, or Leach's kookaburra. [3]
The number of subspecies is unclear - with four recognised by most authorities, although others have proposed that the three Australian subspecies gradually change across Australia and should be treated as one. [4]
The adult blue-winged kookaburra measures around 38 to 42 cm (15 to 17 in) in length and weighs 260 to 330 g. Compared to the related laughing kookaburra, it is smaller, lacks a dark mask, has more blue in the wing, and has striking white eyes. It has a heavier bill than its larger relative. The head and underparts are cream-coloured with brownish streaks. It is sexually dimorphic, with a blue tail in the male, and a rufous tail with blackish bars in the female. Immature birds have more prominent brown bars and marks in their plumage, giving a "dirty" appearance, and their eyes are predominantly brown for the first two years of life. [5]
Their call has been described as a maniacal cackling or barking. [3]
The blue-winged kookaburra has a distribution from southern New Guinea and the moister parts of northern Australia, to the vicinity of Brisbane in southern Queensland across the Top End, and as far down the Western Australian coast as the Shark Bay area. It does not occur between Broome and Port Hedland in northwestern Australia. [4] Widespread and common throughout its large range, the blue-winged kookaburra is evaluated as of least concern on the IUCN Red List of Threatened Species. Found in family groups of up to 12 individuals, it lives in open savannah woodland and Melaleuca swamps, as well as farmlands such as sugarcane plantations. [3]
The blue-winged kookaburra hunts and eats a great variety of animals that live on or close to the ground. [6] In the summer wet season, insects, lizards and frogs make up a higher proportion of their diet, while they eat arthropods such as crayfish, scorpions, and spiders, as well as fish, earthworms, small birds and rodents at other times. [3] They have even been recorded waiting for and snatching insects flushed out by bushfires. [7]
The blue-winged kookaburra is a co-operative breeder, a group being made up of a breeding pair and one or more helper birds that help raise the young. [8] Breeding occurs once a year in late spring (September to December). The nest is a hollow high up in a tree, often 25 m (82 ft) or so above the ground. Three or four white, slightly shiny eggs, measuring 44 mm × 35 mm (1.7 in × 1.4 in) or a little larger, are laid. [9] The female incubates the eggs around 26 days, and nestlings spend another 36 days in the nest before fledging. [3] Chicks are born pink, blind, and naked (i.e. altricial ), and break their way out of the egg with an egg tooth on the bill. Feathers appear by 7 days and their eyes open from the 10th day onwards. [10] Kookaburra hatchlings are often highly aggressive in the first week of life, and the youngest chick is often killed by the older chicks during this period. [11] Once fledged, juvenile birds must be taught how to hunt by their parents for a further 6–10 weeks before they can properly fend for themselves. [12]
The red goshawk and rufous owl prey upon the blue-winged kookaburra. Adult birds are also slow flyers and vulnerable to being hit by cars on country roads. [13] Nests are susceptible to raids by olive pythons, quolls, and goannas.[ citation needed ]
Kookaburras are terrestrial tree kingfishers of the genus Dacelo native to Australia and New Guinea, which grow to between 28 and 47 cm in length and weigh around 300 g (11 oz). The name is a loanword from Wiradjuri guuguubarra, onomatopoeic of its call. The loud, distinctive call of the laughing kookaburra is widely used as a stock sound effect in situations that involve an Australian bush setting or tropical jungle, especially in older movies.
The laughing kookaburra is a bird in the kingfisher subfamily Halcyoninae. It is a large robust kingfisher with a whitish head and a brown eye-stripe. The upperparts are mostly dark brown but there is a mottled light-blue patch on the wing coverts. The underparts are cream-white and the tail is barred with rufous and black. The plumage of the male and female birds is similar. The territorial call is a distinctive laugh that is often delivered by several birds at the same time, and is widely used as a stock sound effect in situations that involve a jungle setting.
The little bittern or common little bittern is a wading bird in the heron family, Ardeidae. Ixobrychus is from Ancient Greek ixias, a reed-like plant and brukhomai 'to bellow', and minutus is Latin for 'small'.
The Indian paradise flycatcher is a medium-sized passerine bird native to Asia, where it is widely distributed. As the global population is considered stable, it has been listed as Least Concern on the IUCN Red List since 2004. It is native to the Indian subcontinent, Central Asia and Myanmar.
Eclectus is a genus of parrot, the Psittaciformes, which consists of four known extant species known as eclectus parrots and the extinct Eclectus infectus, the oceanic eclectus parrot. The extant eclectus parrots are medium-sized parrots native to regions of Oceania, particularly New Guinea and Australia. Males are mostly bright green, females are predominantly bright red. The male and female eclectus were once thought to be different species. The conservation status of the remaining species is least concern. Eclectus parrots do well in captivity, and are a very popular pet across the world.
The rufous-bellied kookaburra, originally known as Gaudichaud's kookaburra after French botanist Charles Gaudichaud-Beaupré, is a species of kookaburra that is widely distributed through the forests of lowland New Guinea.
The spangled kookaburra also called Aru giant kingfisher, is a little-known species of kookaburra found in the Aru Islands, Trans-Fly savanna and grasslands of southern New Guinea. Practically nothing is known of its family life or breeding biology.
The nankeen night heron is a heron that belongs to the genus Nycticorax and the family Ardeidae. Due to its distinctive reddish-brown colour, it is also commonly referred to as the rufous night heron. It is primarily nocturnal and is observed in a broad range of habitats, including forests, meadows, shores, reefs, marshes, grasslands, and swamps. The species is 55 to 65 cm in length, with rich cinnamon upperparts and white underparts. The nankeen night heron has a stable population size, and is classified as a species of least concern by the International Union for Conservation of Nature (IUCN).
The rufous-tailed plantcutter, sometimes called the Chilean plantcutter, is a passerine bird of southern South America, now placed in the cotinga family. It is a medium-sized bird about 19 centimetres (7.5 in) long with a long black tail with a red base. Males have greyish-brown upper parts, a chestnut crown and breast, and dark facial markings. Females are similar but lack the chestnut crown and have streaked, buff underparts. There is a wing bar which is white in the male and buff in the female. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The buff-breasted paradise kingfisher is a bird in the tree kingfisher subfamily, Halcyoninae. It is native to Australia and New Guinea. It migrates in November from New Guinea to its breeding grounds in the rainforest of North Queensland, Australia. Like all paradise kingfishers, this bird has colourful plumage with a red bill, buff breast and distinctive long tail streamers.
The shovel-billed kookaburra, also known as the shovel-billed kingfisher, is a large, approximately 33 cm (13 in) long, dark brown tree kingfisher with a heavy, short, and broad bill that is unique among the kingfishers. It has a dark head with a rufous stripe behind the eyes, a white throat, a rufous neck collar and underparts, a bright blue rump, brown iris, brownish-black bill with paler mandible, and pale feet. Both sexes are similar in appearance, but are easily recognized from the colour of the tail. The male has a dark bluish tail while female's is rufous. The juvenile has a female-like plumage with scale-patterned feathers.
The lesser striped swallow is a large swallow. It breeds in Sub-Saharan Africa from Sierra Leone and southern Sudan south into eastern South Africa. It is partially migratory with South African birds wintering further north. West African birds leave the north of the breeding range in the dry season.
The tree martin is a member of the swallow family of passerine birds. It breeds in Australia, mostly south of latitude 20°S and on Timor island. It is migratory, wintering through most of Australia, New Guinea, Indonesia east of the Wallace Line and the Solomon Islands. It is a vagrant to New Zealand, where it has bred, and New Caledonia. This species is frequently placed in the genus Hirundo as Hirundo nigricans.
The banded kingfisher is a tree kingfisher found in lowland tropical forests of southeast Asia. It is the only member of the genus Lacedo. Male and female adults are very different in plumage. The male has a bright blue crown with black and blue banding on the back. The female has rufous and black banding on the head and upperparts.
The rufous whistler is a species of whistler found in New Caledonia and Australia. Predominantly a reddish-brown and grey bird, it makes up for its subdued plumage with its song-making ability. Like many other members of the Pachycephalidae, it has a variety of musical calls.
The paradise kingfishers are a group of tree kingfishers endemic to New Guinea — with the exception of two species also present in the Moluccas and Queensland.
The moustached kingfisher, also called Bougainville moustached kingfisher, is a species of bird in the family Alcedinidae. It is endemic to Bougainville Island in Papua New Guinea. An estimated 250–1,000 mature individuals are left.
The mountain kingfisher is a species of bird in the subfamily Halcyoninae in the family Alcedinidae. Adult males are 21–24 cm (8.3–9.4 in) long, and have a rufous head and underparts, greenish-blue upperparts, a dark blue tail, and black flight feathers. They also have dark neck patches and loral patches. Females have dark crowns and the neck patches join at the nape. It is similar to the yellow-billed kingfisher, but can be distinguished by its larger size and a proportionally larger bill, along with a dark ridge along its culmen.
The emperor fairywren is a species of bird in the Australasian wren family, Maluridae. It is found in New Guinea in its natural habitat of subtropical or tropical moist lowland forests. It is the largest species of fairywren. It is highly sexually dimorphic. Males have a blue and black plumage, with the females having blue and black plumage only on their heads, with the rest of the body being coloured a rusty brown and having a black tail tipped with white. There are 3 recognized subspecies of the emperor fairywren, one from north and northwestern New Guinea, one from Biak Island, and one from south New Guinea and the Aru Islands.
The tree kingfishers, also called wood kingfishers or Halcyoninae, are the most numerous of the three subfamilies of birds in the kingfisher family, with around 70 species divided into 12 genera, including several species of kookaburras. The subfamily appears to have arisen in Indochina and Maritime Southeast Asia and then spread to many areas around the world. Tree kingfishers are widespread through Asia and Australasia, but also appear in Africa and the islands of the Pacific and Indian Oceans, using a range of habitats from tropical rainforest to open woodlands.
