Cacatua tenuirostris

The long-billed corella or slender-billed corella (Cacatua tenuirostris ) is a cockatoo native to Australia, which is similar in appearance to the little corella. This species is mostly white, with a reddish-pink face and forehead, and has a long, pale beak, which is used to dig for roots and seeds. It has reddish-pink feathers on the breast and belly.


The adult long-billed corella measures from 38 to 41 cm in length, has a wingspan around 80–90 cm, and averages 567 g in weight. It has a long, bone-coloured beak, and a rim of featherless, bluish skin around the eyes. The plumage is predominantly white with reddish feathers around the eyes and lores. The underside of the wings and tail feathers are tinged with yellow.



Biogeographical realms

The long-billed corella can be found in the wild in Victoria and southeastern New South Wales. It has extended its range since the 1970s into Melbourne, Victoria and can now be found in Tasmania, South Australia and southeast Queensland. A feral population resides in Perth, Western Australia as of the mid-1980s, which has conservation implications as this species may hybridize with the endangered western corella.

Diet and Nutrition

The long-billed corella typically digs for roots, seeds, corms, and bulbs, especially from the weed onion grass. Native plants eaten include murnong Microseris lanceolata, but a substantial portion of the bird's diet now includes introduced plants.

Mating Habits

Breeding generally takes place in Austral winter to spring (from July to November). Long-billed corellas form monogamous pairs and both sexes share the task of building the nest, incubating the eggs, and caring for the young. Nests are made in decayed debris, the hollows of large old eucalypts, and occasionally in the cavities of loose gravely cliffs. 2–3 dull white, oval eggs are laid on a lining of decayed wood. The incubation period is around 24 days and chicks spend about 56 days in the nest.



Long-billed corellas are now popular as pets in many parts of Australia, although they were formerly uncommon, and their captive population has stabilised in the last decade. This may be due to their ability to mimic words and whole sentences to near perfection. The long-billed corella has been labeled the best "talker" of the Australian cockatoos, and possibly of all native Psittacines.
