Cassowary

The cassowary is another member of the long-legged, flightless ratites. The Aru Islands, northern Australia, and New Guinea are all home to three living species. Cassowaries are known as the "world's most dangerous bird" and have a fearsome reputation among birds who cannot fly. Its size, razor-sharp claws, and aggressive demeanor when trapped or threatened to earn it this title.

They can weigh up to 130 pounds and range in height from 5 to 6.6 feet. Their tiny wings are terminated with stiff, keratinous quills that resemble those of a porcupine but lack barbs. Cassowaries have a blue wattle on their neck and a huge, age-related golden or blue casque on their heads. Cassowaries have a top speed of 30 mph and are good swimmers and long-distance jumpers. Fruits make up the majority of their diet, along with tiny invertebrates, birds, rats, and fish.
