Australian ravens are opportunistic feeders, eating anything from carrion to biscuits and bread — they have been seen dipping pieces of these into water to soften them. They will bash snails against rocks to get at their insides. Sometimes they even steal golf balls, mistaking them for eggs.

The sulphur-crested cockatoo communicates with extremely loud screeching calls. The cacophonous noise from a rowdy flock can be near-deafening. As these birds forage on the ground with their flock, there is usually a lookout who sits in the trees and gives an alarm cry if danger approaches.
