Corella facts tell us about the bird also known as bare-eyed cockatoo

The little corella (Cacatua sanguinea) has many names: bare-eyed cockatoo, blue-eyed cockatoo, blood-stained cockatoo, little cockatoo, and short-billed cockatoo. These birds are native to Australia and Southern New Guinea. In the west of Western Australia, Pilbara, these birds are called Birdirra. There are three sub-species of corella throughout Australia; the Western corella is confined to the extreme south of Western Australia. The long-billed corella is also one of the subspecies from South East Australia. These birds are primarily white.

These little corellas are usually found in flocks, and at night they roost on trees nest and feed on the ground during the morning. Cockatoos are just like parrots; they are intelligent, easily trainable, and playful birds. These little corellas are spread across Australia; they are adequately populated with minimum posable threats. Therefore, their Conservative Status is under the Least Concern category.

Did you know...

The difference between a corella and cockatoo needs understanding. Several white cockatoos fall in the corella group (subgenus licmetis). The cockatoo is from the same family, Cacatuidae (parrot family), with curved beaks and Zygodactyl foot.

Cockatoos mate for life and both sexes equally participate in incubating eggs and raising young chicks.

Corellas can be loud, noisy beings when uncomfortable and have behavior phobias that make them screech loudly.

Corellas usually flock in large numbers and feed on agricultural crops, which can cause damages.

The process of training a corella is similar to any other pet animal. Treating and rewarding with their favorite foods for obeying commands is the best technique. This also helps them to be responsible pets. Yelling and shouting should be avoided as it causes emotional distress to cockatoos and leads to behavioral phobias.

Different types of corella

C. s. normantoni is slightly smaller, and it has a brownish color under the tail and flight feathers.

C. s. gymnopis has distinct pink lores, yellow wash on lower-ear coverts, and darker blue eye-rings.

C. s. transfreta, is the same as subspecies normantoni but has yellow-brownish underwings and under the tail.

C.s. westralensis looks the same as subspecies gymnopis, but bright orange/red lores and more color washed from the head to upper breast and gradually blends with lower underparts and thighs. It has deep yellow underwings and under the tail.

Cacatua tenuirostris, commonly known as sulfur-crescent cockatoo, has an elongated bill and reddish-pink feathers on its face, neck, and belly.

Are corellas considered pests?

White corellas sometimes form huge flocks and search for food and water. Once they find farmlands and agricultural lands, they feed on crop seeds and cause catastrophic damages.

There was a tragic incident in 2019 July, with hundreds of corella falling from the sky, wailing, bleeding from the mouth, and dying. It looked like a doomsday movie climax, but this is a real incident in Australia. Studies on these bird corpses confirmed the presence of toxic or poison in toxicology reports. However, Sarah King, Casper's Bird Rescue founder, confirmed that poison should be bought post-registration for using this deadly poison and the concluded reports took a long time to take any plan of action.

It's reported that long-billed corellas causing damages like chewing streetlights, damaging building infrastructure, sporting equipment, damaging crops, and displacing other native species of birds, bees, possums, etc. Hence the urban council has ordered culling.
