I heard the commotion from 300m away. I rushed to the tree. A dozen aggressive, raucous cockatoos were harassing a sun-baking young goanna until it was driven from its 10m high tree branch. Tongue flicking, tailed curled behind, the goanna crept over a tree hole where I had seen a pair of King Parrots just an hour before. It quickly climbed head-first down the tree trunk to the ground where it lay in the sun for a few minutes before ambling off into the dense undergrowth to hunt for another day, ego bruised as an apex predator but otherwise unscathed.
