Corellas form large, noisy flocks and are often found feeding in large groups on the ground. Little Corellas were not found on the coastal plain near Perth until the 1970s. They are now a very common urban bird and are often considered to be a nuisance. Little Corellas are intelligent and playful, often hanging upside down, swinging on twigs, hanging on with their bills, and sliding down metal roofs. This Little Corella flock had taken over a sandpit with swings on it for children at Herdsman Lake near Perth, and made the most of the opportunity by playing games like “King of the Castle’, chewing the rubber seats of the swings and hanging upside down amongst other hilarious antics.
