Two of the birds had dirty coloured feathers (photo 1) and no indication of any reddish feathers. The bird in photos 2 and 5 appear to be the same bird. The top head feathers were permantly raised like a crest regardless of wind. The two birds in photos 3 and 4 were chewing the bark of the tree. A flock of corellas have been in this area for a few weeks now.
