Western Corella or Little Corella?

General appearance

The Western Corella is a large cockatoo native to Australia, most prominently displaying a white plumage. Its most characteristic features include a long, white crest, a hooked beak, and a blue-grey eye ring. The under-wings and tail exhibit a pale yellow color. Importantly, these birds are known for their distinct, loud call, making them easily identifiable in the wild.

Male vs female

Sexual dimorphism is not prominently exhibited within the Western Corella species. Both males and females exhibit white plumage, with pale yellow under-wings and tails. The main difference lies in the iris coloration: males have a dark iris while females possess a lighter, reddish color. Size may also vary, with males being slightly larger than females.

Juvenile

Juveniles of Western Corella species resemble adults, but are generally smaller in size. Their eye coloration is distinctly different from adults, with juveniles showcasing a grey iris which later turns to dark in males, or light reddish in females. Their beaks and feathers also display a softer texture than found in adults. Changes in these characteristics signal the onset of maturity.

Primary habitat

The western corella, native to Australia, primarily inhabits woodlands, forests, and significant urban areas.

Additional range

Though usually found in Southwest Australia, it has adapted to suburban environments and is occasionally observed in city parks and gardens.

Natural diet

The western corella primarily feeds on seeds, grains, fruits, and nuts. It favors seeds of native plants, grains from agricultural land, and occasionally insects. These birds are often seen foraging on the ground for fallen seeds and plant material.

Bird feeders

At bird feeders, western corellas are attracted to a variety of seeds such as sunflower seeds, millet, and oats. They might also consume fruits and nuts provided in feeders, making them adaptable to human-influenced environments.
