What is the difference between the Emu (Dromaius novaehollandiae) and the Greater Rhea (Rhea Americana)?
The Emu and the Greater Rhea are large fightless birds. The Emu and the Greater Rhea are both ratites, because they cannot fly (the Ostrich, Kiwi, and Cassowary are also ratites).
The Emu and the Greater Rhea have a large, soft, grey-brown feathered body, a long featherless neck, and long featherless legs with three toes.
The Emu has orange-brown eyes, whereas the Greater Rhea has blue to brown eyes.
The Emu has a tuft of longer feathers on its head, whereas the Greater Rhea does not have head feathers.
The Emu is native to Australia, whereas the Greater Rhea is native to South America.
The Emu is the second tallest bird in the world (after the Ostrich), and the Greater Rhea is shorter, but it is the tallest bird in South America.
