Australia: Corvids and other big (mostly) black birds!
The white-backed form of Australian Magpie, down in Melbourne.
And the black-backed form (a juv) up in Sydney.
And this one... it was in the Otway Ranges along the Great Ocean Road west of Melbourne, so within range for Forest and Little Raven. It didn't call or fly, so I can't really decide what it is. Anyone know?
