Blue-winged kookaburra Blue-winged kookaburra The blue-winged kookaburra ("Dacelo leachii") is a large species of kingfisher native to northern Australia and southern New Guinea. Measuring around , 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
Rufous-bellied kookaburra and rufous in females and immature birds. Rufous-bellied kookaburras are smaller than other kookaburra species at around as against the laughing kookaburra's and about as against the laughing kookaburra’s . Despite this major size difference, the rufous-bellied kookaburra has been known to form (infertile) hybrids with all other kookaburra species, though available genetic studies suggest it is clearly the most distant of the four. This kookaburra is unusual in that it occupies dense rainforests (as opposed to the open country preferred by other kookaburras) and does not live in cooperative breeding family groups but singly or when breeding in pairs.
