Blue-winged Kookaburras are birds. As such, like all birds, they reproduce by laying eggs. The kookaburra does not build a nest out of sticks and/or grass. Kookaburras lay up to three eggs in a nest they hollow out of an old termite nest, or a hollow already in a tree, which they will sometimes enlarge with their strong beaks.
Birds, they also house nest in them.
