Gang Gang pair flew in from south-west and landed in tree at 7:40. Originally perched in higher branches where they were hassled by noisy miners and rainbow lorikeets. At 7.50 moved about 1/3 of the way down tree and chewed bark , still being hassled. at 7.55 another male GG flew into top of tree. At 8.00pm he was joined by female flying in from the west and they both then flew off in the direction of Garran. At 8.00pm the male and female moved down and looked into hollow on lower branch. The same one that Jacky saw a gang gang enter. The birds did not enter hollow this time. At 8.10 they flew off to the north-west. At 8.20 I saw a pair of Gnag Gangs roosting in a yellow box tree near the clubhouse, but I can't be sure that they were the same birds. Rainbow lorikeets also looked into the same hollow as the Gang gangs did.
