Southern cassowary

Today we’re venturing into a tropical forest in Queensland, Australia to visit the southern cassowary, the largest of three species of this flightless bird. The cassowary, like this doting father and his chicks, is known by many as the world’s most dangerous bird because of its sharp, dagger-like claws and aggressive behavior. In the wild, adult birds are so belligerent that they have no natural predators.
