Obviously just visiting. It doesn't look much like a Gum tree.
We had this bloke grunting around the place last night, and he's moved into a tree in our front yard for the day. It's wonderful that we can often see them in our suburban neighborhood trees.
Don't let him move in permanently. They can strip a tree given enough time. Give the tree a chance to recover and give him a call for a return visit.
You would have seen the Gums around Cape Otway.
Pretty amazing that they're so tame.
