Angry bird, doting dad. Father’s Day

Happy Father’s Day! To celebrate, we’re venturing into a tropical forest in Queensland, Australia to visit one of nature’s most protective fathers, the southern cassowary. The flightless cassowary, like this doting father and his chicks, has earned the title of the ‘world’s most dangerous bird’ because of its dagger-like claws and aggressive behaviour. Cassowaries are notorious for attacking and sometimes killing domestic animals and even humans. In the wild, adult birds are so belligerent that they have no natural predators. Their young, however, need some protection. That’s when dad steps in.

Once a mother cassowary lays eggs, she essentially abandons the family and moves on to start another. But dad stays, sitting on the eggs for upwards of 50 days, adding or removing nesting material to keep their home comfortable. Upon hatching, chicks can stay in the nest for nine months. Dad stays by their side, taking them out to feed and teaching them the ways of the world.

Snakes, lizards and eagles that try to capture a cassowary chick are often met by extremely aggressive kicks with claws that can eviscerate attackers. Once his children come of age, papa cassowary chases them away and gets ready to do it all again with another brood. While there are no reports of his kids returning to deliver ‘World’s Greatest Dad’ mugs, the male cassowary’s dedication to fatherhood has earned our admiration.
