The name "rhea" was used in 1752 by Paul Möhring and adopted as the English common name. Möhring named the rhea after the Greek Titan Rhea, whose Ancient Greek name (Ῥέα) is thought to come from ἔρα (éra, "ground"). This was fitting with the rhea being a flightless ground bird.

It is much attracted to sparkling objects and sometimes accidentally swallows metallic or glossy objects.
