There was a lone Black-faced Cuckoo-shrike on Aspen island. A Noisy Miner was doing its best to disturb it but the cuckoo-shrike was not being scared off. There was also a Brush-tailed Possum nearby, trying to apparently curl up in the open part of where the top of the tree had come away. I am not sure if this was making the bird uneasy as possums will eat eggs and young birds, although I could not hear a second bird nor did this one seem to be attacking the possum.
