Muir's corella (''Cacatua pastinator pastinator'') is a stocky, medium-sized white cockatoo endemic to Western Australia. It was the threatened nominate subspecies of the western corella.〔Anon. (2007). ''Muir’s Corella''. (Fauna Note No.4). Department of Environment and Conservation, Western Australia.()〕 It was removed from the WA’s threatened species list in November 2012 as a result of successful conservation efforts.〔(May (2012). ''Cockatoo, contentious moth back from brink''. Herald Sun )〕 ==Description== Muir's corella has mainly white plumage with an erectile white crest. The undersides of the wings and tail are yellow. The feathers between the eye and beak are deep salmon-pink, as are the bases of the feathers on the head and underparts. The eye is surrounded by a broad grey-blue eye-ring. The white feathers are often stained with soil because of the birds’ foraging activities. The corellas have a wingspan of 90 cm,〔 and range from 43–48 cm in length and 560–815 g in weight. They have a variety of loud and raucous calls.〔 They are very similar in appearance to Butler's corella, the only other subspecies of the western corella, being slightly larger with a longer upper mandible.
