Dec 18, 2019 · An ostrich-like bird, the Darwin’s (or Lesser) rhea is one of the most distinctive, fabled and endangered residents of the Chilean steppe. Rheas do not fly, but thanks to their unusually large wings, which they spread behind their bodies while running from predators, they can sprint at speeds over 50 kph. Two species of rhea, the Greater and Lesser, occupy overlapping ranges in Patagonia which straddles Argentina and Chile.
However, they are classified as Rhea tarapacensis by the IUCN, which regards it as being near threatened, with the primary threats being hunting, egg-collecting, and fragmentation of its habitat due to conversion to farmland or pastures for cattle-grazing.

The rhea lives in wild only in South America, among other things in Argentina, Brazil, Peru, Bolivia, Paraguay and Uruguay. Both species: the lesser rhea (Rhea pennata) and the greater rhea (Rhea americana) prefer open areas. The first one chooses grassland, the scrubland and even salt desserts. It lives in areas at the height of not more than 4500 m above the sea level. The second species likes open grassland, pampas and it most willingly stays next to water; it lives in lowland areas most often and it rarely exceeds the height of 1200 m above the sea level.
The rhea is a big flightless bird with grey-brown plumage, a long neck and it stands on long legs. It is very similar to the North African ostrich (Struthio camelus). The lesser rhea is a little bit smaller than the greater rhea. While walking, the bird spreads its wings which act as sails. Contrary to the majority of birds, the rhea has got only three toes. Its urine is stored in the separate organ out of the cloaca, which keeps feces.
The rhea is omnivorous but it prefers leaves, seeds, roots, fruit as well as small rodents, reptiles and insects.
The rhea is a typical polygamist- the male mates with 2-12 females during one mating season. After the copulation, it builds the nest where the female lays eggs. The nest is full of branches, leaves and grass inside. The father incubates from 10 to 60 eggs and meanwhile, the female goes on the mating activities. The incubating male may be more aggressive towards other rheas (especially females) and people. These birds do not reproduce till the age of 2.

Its plumage is white-brown and the upper part of legs is also covered with hairy feathe...

It lives in Uruguay, Argentina, Paraguay, Bolivia and Brazil; it chooses open areas such as grassland, savannahs, scrubland, desserts, backwater and maquis.
