About the Southern Cassowary
Southern cassowaries, also called double-wattled cassowaries, can stand 6 feet tall and weigh 100 to 150 pounds. They live in the rainforests and savanna woodlands of New Guinea and northeastern Australia. Coarse black feathers protect them from thorns, and they can run up to 30 miles per hour through thick brush. They eat fruit, insects, eggs, frogs, fungi and carrion. They are also strong swimmers.[1]
