The Eastern Long-billed Corella poses an environmental threat to our endemic black cockatoos by out-competing for nest sites, their ability to remove eggs from the nest hollow and to kill and maim advanced nestlings. This introduced species (derived from aviary escapees around Perth) is a major threat to our endemic corellas and black cockatoos. It is characterised by having a very long upper bill and its whole face is bright orange-red and it has a bright red neck giving it a cut throat appearance. The Eastern Long-billed Corella Cacatua tenuirostris is now well established around Perth and on the southerly Swan Coastal Plain to Busselton. Western Long-billed Corella (Muir’s Corella). Refer to the ‘Western Long-billed Corella.pdf ’ information sheet for more details. There are two subspecies – Muir’s Corella and Butler’s Corella. Unfortunately this bird is no longer found around Perth where it once occurred fairly abundantly. The Western Long-billed Corella Cacatua pastinator has a much longer bill than the Little Corella and has more extensive orange-red colour visible on the face and throat. It is the smallest of our corellas, has the shortest bill of all the corellas and has a narrow band of dull orange-pink below the bill and eye. The Little Corella Cacatua sanguinea is the common white cockatoo in the north- and mid-west of the State.

However, in other species, such as the Sulphur-crested cockatoo, adults are of the same size and only display minor differences which can’t be easily observed, especially from a distance. For example, female Salmon-crested cockatoos are sometimes larger than their male counterparts. Anecdotal evidence does suggest some differences, but these are unreliable. In other words, a male cannot be distinguished from a female simply by looking at the two birds.
