Overview

They resemble smaller, three-toed ostriches and are strong runners that roam grasslands and pampas in loose flocks. Rheas are omnivorous, taking leaves, seeds, fruit and invertebrates, and the male alone incubates the eggs and cares for the young. They are the New World ecological counterpart of the African ostrich and are locally farmed and hunted.
