This is a European Carrion Crow (Corvus corone), a non-native and non-protected species of corvid which doesn't need any permits to own Australia wide.

I received this skeleton macerated, but I degreased and whitened it myself before building. It's complete with nail sheaths, beak sheaths, and even sclerotic rings. It isn't attached to the base, so it can be removed to make shipping/transport easier. This guy is available Australia wide
