Cassowaries are large, flightless birds that can measure up to six feet in height and weigh between 100 and 150 pounds. They have powerful legs and can run up to 30 miles per hour. They are from Australia and New Guinea.

Like emu and rhea, the male remains with the eggs and chicks. Chicks are able to walk and feed themselves within a few hours of birth. Male and female chicks leave the nest in about two days, and stay together about nine months.
