Other forms: ostriches
An ostrich is a huge, flightless bird with long legs and two toes on each foot. Although they weigh as much as 265 pounds, ostriches can run almost 45 miles per hour.
Ostriches are related to emus, but they're about three times larger. There are two modern species of ostrich, both native to Africa. Ostriches are often farmed for their distinctive soft, loose feathers (which are used in feather dusters and in fashion design). Colloquially, an ostrich is also someone who avoids difficulty by refusing to face it, a use that comes from the birds' habit of putting their heads in the sand — although they do it to hunt for snacks!
