These arboreal termite mounds seem to be the preferred nest site for Kookaburras and other kingfisher species. They will also utilize hollow trees, earthen banks, and even holes in walls when better sites are unavailable. Burrows may be two feet deep with an entrance hole four inches in diameter. Two to four white eggs are laid on the bare substrate of the nest chamber. Both parents participate in the 25-29 day incubation.
Hatchlings emerge blind and practically naked.
The eyes may not open completely until the bird is nearly 3 weeks old. Parents feed the young a diet consisting primarily of insects, as they remain within the burrow for a full month. When they finally are coaxed from the nest they are already able to fly. The parents continue to feed the fledglings for several weeks after they emerge from the nest. The birds will remain together as a family group until the next breeding season begins.
