Largest bird?

The Southern Cassowary is the second-largest bird in Australia and the third-largest remaining bird in the world (after the ostrich and emu). Adult Southern Cassowaries are 1.5 to 1.8 m (5 to 6 feet) tall, although some may reach 2m (6 feet 8 inches), and weigh about 60 kilograms (130 pounds). They have a bony casque on the head that is used to batter through underbrush, making them the only armoured bird in the world. Females are bigger and more brightly coloured.
