Greater Rhea

Rhea americana

Near Threatened

The Greater Rhea is South America's largest bird, looking like a smaller cousin of the ostrich. These flightless birds roam the grasslands of Argentina and Brazil in small flocks.

Rheas are unusual parents - one male will mate with several females, and then HE sits on all the eggs and raises all the chicks himself!
