Cassowary are flightless, shy yet dangerous birds which are native to the humid rainforest. They are third tallest and second heaviest birds in the world. Mainly fed on fruits (fallen from trees) but are truly omnivorous. Cassowary are ancient prehistoric birds that began to evolve around 60 millions years ago from a group of carnivores dinosaurs known as ‘theropods’ which walked on two legs. They existed since the Cretaceous period when dinosaurs were the dominant animal life on earth.Cassowary are the endangered birds, only 1200 left in the world now.
