Cassowary

Before cassowaries attack they plump up their feathers to make themselves look large and make a deep booming sound. These flightless birds have attacked and killed humans before using their enormous talons. And just because theyre flightless doesnt mean they arent fast; cassowaries can run up to and over 30 mph. It is not uncommon for tourists to see the goofy looking bird and want to get a closer look not knowing how dangerous the animal actually is. Cassowaries will defend their chicks to the death Most likely your death. Unfortunately, all three species of cassowary are endangered, for centuries they had no predators but nowthey are a huge target for hunters.
