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 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. 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.

The blue-winged kookaburra hunts and eats a great variety of animals that live on or close to the ground. 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. They have even been recorded waiting for and snatching insects flushed out by bushfires.

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.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. The female incubates the eggs around 26 days, and nestlings spend another 36 days in the nest before fledging. 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. 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. 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.

 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. Nests are susceptible to raids by olive pythons, quolls, and goannas.

10-10-2000 SYDNEY, AUSTRALIA - BLUE WINGED KOOKABURRA (Dacelo leachii)

The blue-winged kookaburra (Dacelo leachii) is a large kingfisher, slightly smaller than its cousin, the laughing kookaburra. It boasts a cream-colored plumage with brownish bars, blue wings, and a blue rump. The male is distinguished by its blue tail, while the female's tail is rufous with blackish bars.

Adults measure 38 to 42 cm in length and weigh between 260 to 330 grams. They lack the dark mask of the laughing kookaburra, have more blue in the wing, and striking white eyes. The bill is quite heavy. Juveniles can be identified by their more pronounced brown bars and marks, and their eyes are brown for the first two years.

This species is found in open savannah woodland, Melaleuca swamps, and farmlands, including sugarcane plantations.

The blue-winged kookaburra's range extends from southern New Guinea and northern Australia to Brisbane in southern Queensland, across the Top End, and down the Western Australian coast as far as Shark Bay.

They live in family groups of up to 12 individuals and are known for their maniacal cackling or barking calls.

The call of the blue-winged kookaburra is a distinctive and loud cackle or barking sound.

A cooperative breeder, the blue-winged kookaburra nests in tree hollows, with a breeding pair assisted by helper birds. They lay three to four white, slightly shiny eggs, and chicks are altricial, requiring extensive care post-hatching.

Their diet varies seasonally, including insects, lizards, frogs, crayfish, scorpions, spiders, fish, earthworms, small birds, and rodents. They are opportunistic and may even snatch insects fleeing from bushfires.

The blue-winged kookaburra is listed as Least Concern on the IUCN Red List of Threatened Species. However, they face predation from red goshawks and rufous owls, and adults are at risk of vehicle collisions. Nests may be raided by olive pythons, quolls, and goannas.
