The cassowary is one of the most interesting bird species. Mostly known as the most dangerous bird on the planet. The cassowary is a type of flightless bird (ratite) that belongs to the order of Casuariiformes. These long-legged, large birds are cousins to the emus and have 3 subspecies, the most common being the southern cassowary. They can be found in the tropical forests of New Guinea, the northeastern part of Australia, and the Aru Islands.
1. The southern cassowary is Earth's second-heaviest bird.
Scientists recognize three living species of cassowary—all of which live in New Guinea, northeastern Australia, and nearby islands. The dwarf cassowary is the smallest, with an average height of around 3 feet. The northern cassowary, an orange-throated behemoth, can stand nearly 5 feet tall. The southern cassowary is bigger than both at 5 foot 6 inches tall. The only two birds that grow taller are ostriches and emus. Adult southern cassowary females can weigh up to 157 pounds, and males 121 pounds, making them the second-heaviest birds on the planet behind ostriches.
