Description
Rheas are large, flightless birds with gray-brown plumage, long legs and long necks, similar to an ostrich. Large males of R. americana can reach 1.70 metres (5.6 ft), and weigh up to 40 kilograms (88 lb), and their back can be 100 centimetres (39 in) tall. The Lesser Rhea is somewhat smaller as their back is only 90 centimetres (35 in) tall. Their wings are large for a flightless bird (250 centimetres (8.2 ft)) and are spread while running, to act like sails. Unlike most birds, rheas have only three toes. Their tarsus has 18 to 22 horizontal plates on the front of it. They also store urine separately in an expansion of the cloaca.

“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
