The Greater Rhea looks similar to an ostrich but they are much smaller. They also have three toes on each foot, while ostriches have two. Rheas cannot fly, but they have unusually long wings for flightless birds. They use their wings like an airplane rudder to help them dodge predators and for balance while running.

Rheas are the largest South American bird. They weigh between 33 and 66 pounds (15 and 30 kilograms) and stand 3-5 feet (0.9-1.5 meters) tall. Males are typically larger than the females.
The greater rhea is found in southeastern South America, including Brazil, Bolivia, Uruguay, Paraguay and Argentina, where it lives in grassland and semiarid scrubland.
