I have just photographed a butcherbird in Ashgrove with a bad eye problem am not sure if BirdLife Aust. would want to know about it. It appears to be an immature bird. The right eye seems to have been infected and has mostly recovered however the left one is pretty bad & looks very nasty. I have taken quite a few pics. and am not sure if it needs to be brought to someone's attention.
Hi Burrago, if the bird seems to be struggling with day to day activities, the link below contains a list of wildlife rescue organisations, hopefully there is one near you. Thanks for posting, and I hope it foes well for the Butcher Bird.
