Are they not seeking larvae in the trunk? Many examples on Mount Majura in Eucalyptus brigesiana.

Hi Kym,

I enjoy your regularly posted photos to this chatline.

As to the reason that Cockatoos bite the bark off trees, I don’t buy the one about goannas. The reason being that I have seen goannas climb dead trees with no difficulty. The same with feral cats.

However, I don’t have an explanation for this behaviour. It might be related to the activity of Sulphur Crested Cockatoos chewing on balcony timber in the suburbs of Sydney.

Wondering if she is in the early stages of ring barking to prevent goannas etc climbing to the nest as the tree is full of possible nest holes for future nesting ?????????????????????
