CommentImage specific (01.08.21BiLMkII_BOZ0645); the image is that of a ♂ Forest Red-tailed Black-Cockatoo, ssp. Calyptorhynchus banksii naso, which is endemic to WA and listed by Museum of WA as 'Vulnerable' per 07.01.19:
Walking back to my car from the floating viewing platform at Bibra Lake, I suddenly found myself in the midst of a feeding flock of Forest Red-Tailed Black-Cockatoos. The flock numbered about 20, and it had several loudly begging youngsters within it, these being fed by their mothers in the crown of Marri trees. Marri and Jarrah Eucalypts mature patchily, so you never quite know when these majestic black-cockatoos will be visiting; the nuts of these trees have to be just right, before the birds will start to forage in them. When a tree or a patch of trees are exhausted of their nuts, the birds will move on to another source of ‘just right’ trees to feed upon. This image shows how a Marri nut is held and treated to the powerful bill of this male black-cockatoo, until the seeds inside are cleverly extracted. Personally, I do suspect that some of the soft, nut flesh is also eaten, but I have not been able to find research results about this specifically
