This large gum tree had a beautiful trunk and several hollows. A galah flew to one of the hollows ( pics 1 &2), entered it and came out again after a few minutes and had a good look around. It then flew to perch on a nearby branch (pic 4). Soon after a second bird came out for a few minutes and the two sat outside for awhile (pic 6) before flying away together.
Spotted in a reserve near a creek.
