Little corella

The little corella, scientifically known as Cacatua sanguinea, is a species of white cockatoo native to Australia and southern New Guinea. This bird is recognizable by its predominantly white plumage and a distinctive feature of having upper and lower mandibles of similar length, setting it apart from some related species. It is also known by several other common names, including the short-billed corella, bare-eyed cockatoo, and blood-stained cockatoo.

Distribution and Habitat

Little corellas are widespread across mainland Australia, inhabiting a broad arc from eastern South Australia through Victoria, New South Wales, Queensland, and the Northern Territory, extending to coastal Western Australia. They are also found in southern New Guinea and have been introduced to Tasmania. Their preferred habitats include savannas, shrublands, and grasslands, as well as urban environments. They are adaptable and can be found from the arid deserts of central Australia to the eastern coastal plains, though they tend to avoid thick forests. In urban areas, they are known to frequent parks, gardens, and playing fields.

Description and Behavior

This small cockatoo typically measures between 35 to 41 cm in length and weighs between 370 to 630 grams, with females generally being slightly smaller than males. They are often seen congregating in large flocks, which can number in the thousands and may include other cockatoo species and parrots. These flocks typically roost in trees overnight and fly out to feed in the early morning and late evening, sometimes traveling considerable distances for food and water. The species is known for its noisy vocalizations, characterized by high-pitched notes and screeches that can be deafening when large numbers call simultaneously.

Diet and Breeding

Little corellas primarily feed on the ground, consuming a variety of seeds, both from wild plants and cultivated crops such as wheat, barley, and maize. Their feeding habits can sometimes lead to them being considered agricultural pests. They also regularly feed on lawn grasses in urban areas. Breeding usually occurs between May and October, with nesting sites typically found in tree hollows, cliff cavities, or termite mounds. The nesting season tends to begin earlier in the northern parts of their range.

Relationship with Humans

Historically, indigenous peoples such as the Yindjibarndi kept little corellas as pets and also cooked and ate them, using their downy feathers in traditional ceremonies. In some regions of Australia, they are considered unprotected native fauna and may be subject to culling by landowners due to crop damage or structural damage they can cause. Permits can also be obtained for taking a limited number of these birds from the wild for avicultural purposes. The species has unfortunately also been subject to suspected poisoning incidents, highlighting the complex interactions between wildlife and human activities.
