The Evolution of Australia's Corvids

Corvus is a cosmopolitan genus of over forty species. Australia's five ravens and crows are members of the genus.

Australia's Corvids have white eyes and a general similarity to one another that occurs nowhere else. It is conjectured that they diverged from a single ancestral population that arrived when Australia was a forest-covered continent, around ten thousand years ago.
