In the southwest corner of Western Australia, two species (or perhaps subspecies) of white-tailed black cockatoos occur: Baudin's, or long-billed black cockatoo and this species: Carnaby's, or short-billed black cockatoo. These species closely resemble each other, and even the bill length is not strikingly different. Both are large, imposing, noisy, social birds that look much like the yellow-tailed black cockatoo of eastern Australia, except that the yellow of the latter is replaced with white. Like other large cockatoos (such as the red-tailed black cockatoo of northern Australia), white-tailed blacks use their large, powerfull bills to open thick-shelled seeds and nuts, but they also feed on other plant material. These were in the tiny town of Porongorup, Western Australia. Like all cockatoos, white-tailed blacks breed in tree cavities and many were inspecting holes high up in tall eucalypts (below, left). |
