Potential nesting site. This pair of Gang-gangs were showing interest in hollows in two adjacent trees with multiple hollows. Another pair were perched in a different tree about 50m away.
Thanks David - interestingly it is a different female to the one Lisa saw in the same tree a few weeks ago - did you notice if the female 50m away had large pink blotches or her face or not?
No problem Michael, and yes the female up the trail a bit did have pink blotches on her face. She was quite high up and I couldn't get great photos, but you can see her and the tree location here: https://inaturalist.ala.org.au/observations/234841511
