The adult landed in a tree 50 metres away from the nest, with its latest catch, a Green Tree Frog. Its whistling alerts the chicks, while it transfers the frog to its beak. It then flies to a perch beside the nest, and seconds later one of the chicks gets fed.

This pair of Kookaburras appear to be raiding the nest of a Forest Kingfisher. They would take turns to fly at the nest from a nearby perch, and peck inside. They would only remain at the entrance for a couple of seconds before returning to their perch, or sometimes retreat immediately. I couldn't be sure, but it seems that there may have been an adult Kingfisher inside, defending the nest. One of the Kookaburras has feathers stuck to its beak.

They may also have been chipping at the nest entrance to gain better access, because it seems larger than in this earlier observation: https://www.inaturalist.org/observations/195180694
