This male Gang-gang was moving between 2 trees before he settled on a high branch. A male and female flew in from the east, possibly from Red Hill, with the female flying through but the male landed on the branch where the initial male was. The 2 males started squawking before they launched at each other, claws first. They locked claws, while spinning down, coming down through the lower foliage before they broke apart and the recent arrival flew straight off to the west, while this male grabbed hold of a very low branch. He steadied himself and flew to another tree. He moved around the branches in that tree calling. At the same time as he was calling he would raise both his wings. He seemed to be responding to possibly two other Gang-gangs who were making a similar call. There was one to the west and possibly another Gang-gang to the south. This male inspected a hollow in the second tree but there was no female and he did not stay in this tree long but flew back to the first tree.
