The night parrot was believed to be extinct for almost 80 years. Despite widespread sightings throughout mainland Australia, this nocturnal parrot is one of the country's most elusive birds. It lives in isolated arid regions, spending most of its time on the ground and hiding within spinifex grass.

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.
