This Long-billed Corella couple were conducting some mutual preening, before they moved to the trunk of the tree where there may have been a hollow, but I was on the wrong side to see. Neither bird went far into the hollow so I am not sure if it was deep or just a scraping.
Hi Ryu and Natureguy, Many thanks for that pick-up. I thought I was still photographing the same pair. I was flicking between them, the SCC and the Dollarbird. Very much appreciate the pick-up on the Little Corella. Cheers
