Big Bird in an Old Forest: Southern Cassowary

Australia's northeastern tropical rain forest, among the oldest forests in the world, is home to a unique, flightless bird. The huge southern cassowary stands 1.8 meters tall and weighs up to 60 kilograms. It maintains an interesting relationship with the surrounding plant life. It can swallow fruits 10 centimeters in diameter, and eat fruit other animals find toxic. The seeds it excretes germinate and sprout into plants. Thus these earthbound birds support the forest that supports them. Some 150 varieties of plants depend on the cassowary for their propagation. This program shows the fascinating relationship between the mysterious cassowary and some of the world's oldest forests.
