Bird: Ostrich

The ostrich may not actually be able to fly, but this African bird can run at speeds of 45 miles per hour when threatened. An adult male ostrich may weigh close to 300 pounds, and can reach a height of 9 feet (about half of which comes from its neck). This last surviving member of the genus Struthio dines on things like berries and grass, and has a progressive approach to the division of household labor: Both females and males take turns guarding and tending to their eggs after a female has laid them.
