The greater rhea is a flightless bird found in eastern South America. Other names for the greater rhea include the grey, common, or American rhea; ñandú; or ema.
The greater rhea body shape is ovular with a long protruding neck. Their head, neck and posterior are covered by brownish gray colored feathers, while the base of the neck, anterior, and dorsal feathers are black, and their ventral feathers are white.
Greater rhea bills and scaled legs are yellowish-brown. Despite the inability to fly, these birds possess relatively large and powerful wings.
Greater rheas use their wings like sails for bursts of speed during running and assistance in turning. They also create displays for potential mates or competitors.

Adult males tend to be from 1.34 to 1.70 meters tall and weight 26 to 36 kilograms. Females average 1.35 meters in height and a weight around 32 kilograms.
