They have short square-ended tails and pointed wings. They have short crests and an elliptical pale blue ring around the eyes with a dark-brown iris. Their bills and legs are gray. They have an extremely long upper mandible. This is a feature distinct to this species. During feeding, the bill is used as a plough to dig a furrow and expose any edible material. The upper mandible grows quickly and is worn-out during feeding. This species is considered by many as one of the most difficult to breed in captivity. This is because of their innate aggressive nature. These birds are generally more noisy than most cockatoos. They have been the cause of many neighbor complaints. They make a quavering contact call “wirup” and also emit some Behavior Voice Long-Billed Corella squeaky conversational notes. They are known to use a “sentinel warning system” to warn the feeding flock of approaching danger. The Long-billed Corella feeds on seeds, nuts, fruits, berries, roots, bulbs, insects and their larvae. They also take newly sown grain and ripening crops, including Sunflower seeds. They feed in flocks of up to 2000 birds during summer and are regarded as crop pests. The breeding season is from July to December. At this time, pairs break away from the flocks to build nests in the hollows of Red gum trees that are lined with decaying wood dust. Sometimes, they also nest in cliff cavities. Up to four white eggs are laid and these hatch in around 29 days. Usually only one chick is reared to maturity and it leaves the nest when it is 7 weeks old. The parents feed the chick for another 3 weeks. Diet Reproduction Long-Billed Corella Subspecies Major Mitchell's Cockatoo has two subspecies.
