Cassowary Stock Video Footage

Typically, all cassowaries are shy birds that are found in the deep forest. They are adept at disappearing long before a human knows they were there. The southern cassowary of the far north Queensland rain forests is not well studied, and the northern and dwarf cassowaries even less so. Females are larger and more brightly coloured than the males. Adult southern cassowaries are 1.5 to 1.8 m (5–6 ft) tall, although some females may reach 2 m (6.6 ft), and weigh 58.5 kg (130 lb). All cassowaries have feathers that consist of a shaft and loose barbules. They do not have retrices (tail feathers) or a preen gland. Cassowaries have small wings with 5–6 large remeges. These are reduced to stiff, keratinous quills, resembling porcupine quills, with no barbs. A claw exists on each second digit of the feet. The furcula and coracoid are degenerate, and their palatal bones and sphenoid bones touch each other. These, along with their wedge-shaped body, are thought to be adaptations to ward off vines, thorns, and saw-edged leaves, allowing them to run quickly through the rainforest. Cassowaries have three-toed feet with sharp claws. The second toe, the inner one in the medial position, sports a dagger-like claw that may be 125 mm (5 in) long.
