A noisy bunch!
Little Corellas are an expressive, social bird with a variety of vocal sounds. The most common is the alarm call, which is a piercing boisterous screech. A variety of contact calls can also be heard from large flocks in flight. Several thousands of corellas have been seen to flock together, mostly at roosting time, midday and night.
Little Corellas are quiet and secretive in their nesting sites. Breeding pairs prepare their site with fresh litter by chewing the inside a tree hollow. Some pairs develop a permanent bond and inhabit the same nesting site over several years.

Although the little corellas roost in trees, they mostly feed on the ground, consuming various seeds and legumes. Some corellas in Western Australia have adapted a longer bill to help them dig up and feed on bulbs.
