The blue-winged kookaburra is a medium sized kingfisher endemic to Northern Australia and Southern New Guinea. They have a characteristically large beak, which aids them in catching and holding prey items. In the wet months, they prey predominantly on reptiles, insects, and frogs. Other times they are known to prey on other birds, mammals, snakes, worms, spiders, and more. When hunting, they will frequently dive at a prey item with their beak wide open, then take it to a branch and beat it before swallowing it.
The main threat to these birds are two larger birds of prey, the rufous owl and the red goshawk, but they are not the main prey for either species. Reptiles and mammals such as the quoll wills also raid the nests. Adults are known to be rather slow flyers, which causes them to be at risk of being hit by cars. Despite these threats, they are widely dispersed enough that they are not an at-risk species.
These birds live in surprisingly large family groups of up to 12 individuals. Broods generally produce three offspring, but can range between two and five. The adults of a breeding pair will share the responsibilities of incubating the eggs, as well as feeding the young. Frequently offspring from the previous year will assist in raising the new clutch. They are sexually dimorphic, with the female having a red-brown tail with black bars, and the male having a dark blue tail.
