context_page_description: The western corella also known as the western long-billed corella, is a species of white cockatoo endemic to south-western Australia.
context_section_description: Cacatua pastinator is a white cockatoo with the upper wing entirely white and under surface of the wing pale yellow. It has an erect white crest, blue grey eye skin, crimson pink colouring between the eyes and beak, a small pink patch on the throat, and long pointed bill. Cacatua pastinator lacks sexual dimorphism and the sexes are difficult to distinguish. Determination of the sex of Cacatua pastinator cannot be determined on the basis of eye colour or plumage, observations of pairs have revealed that the males are larger than the females and have a deeper alarm call. Cacatua pastinator is a medium-sized stocky cockatoo with broad rounded wings, a short tail, and a crest which is usually flattened. Muir's Corella (Cacatua pastinator pastinator) adults range in length from 43–48 centimetres (17–19 in) and weigh 560–815 grams (19.8–28.7 oz). The northern subspecies, Butler's Corella (Cacatua pastinator butleri), are a smaller bird with adults 40–48 centimetres (16–19 in) in length and weighing up to 700 grams (25 oz). The bill is a dullish grey white, the legs are dark grey and the upper mandible has a long tip. The underparts are often stained or dirty as a result of feeding on the ground and digging.
  The flesh of the western corella is described as plump and tender, and suitable for stewing.
