Abstract
The Greater Rhea (Rhea americana) is the heaviest bird in South America and inhabits open environments in Argentina. It has a polygynous reproductive system and the male incubates the eggs and cares for the chicks. In El Palmar National Park, Entre Ríos province, Argentina, an adult male rhea was observed near a cave of the Six-banded armadillo (Euphractus sexcinctus), from which the chicks emerged and headed towards him.
