Why The Cassowary Is The World's Most Dangerous Bird (Pics & Video)

So what exactly is a cassowary? Like their cousins the emus, these large, flightless birds with bristly feathers are ratites. They are native to the tropical forests of south-east Asia and Australia. Though size varies across the three different species (see end of article), cassowaries can stand up to 2 m (6 ft 6 in) tall and weigh as much as 60 kg (132 lb) – the equivalent of six mute swans, which are the heftiest birds native to the UK.
