Although, they share a common name, the Australian magpie is NOT a relative of the magpie of the Crow Family. The Australian magpie (Gymnorhina tibicen) is a relative of the currawong. Found only in Australia, this bird is among one of the most common of local birds there. The Australian magpie tends to live in one place in a large group.
The Australian magpie has a complex social structure. He lives either in a tribe of about two to ten birds or in a flock of many birds. The difference between the two is that a tribe has a breeding territory. Members of his tribe defend their territory from all other magpies. Australian magpies who are members of flocks are usually birds who were unable to join a tribe. These birds do not breed until they join a tribe. When an Australian magpie is about two years old, He is forced out of the territory of his birth tribe and must look for another tribe to join. The only way that an Australian magpie can join a tribe is when another bird leaves.
