The Kookaburra has a very a large head in comparison to it's body. The entire bird is approximately 18 inches long and weighs close to a pound. Its diet consists of lizards, mice, small birds, and an occasional snake. To kill prey, Kookaburras have been observed to take the catch high into the air and drop it, or smash it on a tree branch. They build nests in hollow trees or a termite mound, which protects the nest from predators.
Kookaburras are monochromatic birds that mate for life.
The breeding period of the Kookaburra is from September to January. Their eggs are about the same size as a bantam's and are pure white. The clutch size can vary from one to five eggs, but the most common numbers are two or four. The eggs are laid a day apart, and the incubation time is anywhere from 24 to 26 days. This gives the parents a break because the chicks hatch at these same intervals as well.
