Blue-winged Kookaburra

The Blue-winged Kookaburra is a large terrestrial kingfisher of northern Australia and southern New Guinea. It is a heavy-bodied bird with an oversized bill, a whitish-streaked brown head, pale underparts, and a brown back.

Its common name comes from the bright blue patches on the wing coverts, which flash noticeably in flight. The tail is blue above, barred with black. Males and females differ subtly: males show more blue in the rump and tail, while females tend to have more rufous-brown tail coloring.

Key field marks

• Large, thickset kingfisher with an oversized bill
• Pale, whitish iris (eye) — the single best mark separating it from the Laughing Kookaburra
• Blue patches on the wing coverts, visible at rest and in flight
• Blue tail barred with black
• Streaky brown-and-white head, no strong dark eye-stripe

Similar species

The Laughing Kookaburra (Dacelo novaeguineae) overlaps in parts of Queensland but has a dark brown eye, a bold dark eye-stripe, and much less blue in the wing. Laughing Kookaburra's famous "laughing" song is more melodious than the harsher, more manic cackle of the Blue-winged Kookaburra.

Range

Found across northern Australia, from the Kimberley in Western Australia across the Top End of the Northern Territory to Cape York and central coastal Queensland, and in southern New Guinea.

Habitat

Prefers open eucalypt woodland, savanna, paperbark swamps, mangrove edges, and farmland with scattered trees for perching and hunting. It avoids dense rainforest.

Movement

Generally sedentary, holding permanent territories year-round as family groups.

Voice

Gives a harsh, cackling, almost maniacal call, often described as more raucous and less musical than the Laughing Kookaburra's laugh. Family groups frequently call together in a chorus, especially around dawn and dusk, to advertise territory.

Feeding

A sit-and-wait predator, perching quietly before dropping onto prey on the ground — insects, lizards, snakes, frogs and small mammals — which it kills by beating against a branch.

Breeding

A cooperative breeder: young from previous broods often stay to help parents feed and defend later chicks. Nests are unlined cavities in tree hollows or excavated into arboreal termite mounds.
