      Saved In:

    The largest native living bird of America

    Nino Barbieri

    The largest bird in South America and the state bird of Rio Grande do Norte, Brazil.

    They are grey-off-white in color with long necks and strong legs. Unlike other ratites, their large wings are retained and used while running and for mate display.

    Adults are silent and can forage in large groups in the non-breeding season. Inhibits and nests a variety of South American grasslands such as savannas and pampas. The small population escaped from the zoo/farm of NE-Germany, successfully bred, and settled locally.

    Activities like farming and ranching fragment Greater Rhea’s native habitat. Their population is declining because of poaching and habitat destruction.
