Alternative Name
Greater Rhea
Scientific Name: Rhea americana
Basic Info
Rheas are similar in appearance to the ostrich and are often called 'South American Ostrich.' However, unlike the ostrich, the Rhea has three toes on each foot instead of two. The Rhea stands about five feet tall and weighs about 50 pounds. Both sexes are primarily gray, with a black head, chin and neck. The feet are brownish. The Rhea has larger wings then the ostrich.
Health
Rheas are susceptible to leg problems and impaction.
Chicks should be kept in brooders made of 1" chicken wire with 2' x 4' frames. The brooder should be kept at around 90 degrees. Young chicks need to be encouraged and taught to eat. Also, make sure the chicks are closed up at night to protect them. You should also be careful, when making their housing, not to have any small items, such as bolts and screws, as they will try to ingest them, The pens should be cleaned daily to ensure against disease.
Older animals require grit to help them digest their food and prevent impaction. A combination of oyster shell, for calcium and crushed granite, is a good source of grit. Water should be available at all times.
Rheas need plenty of room to exercise.
Habitat
Low-lying plains found in the Campo region of South America
Behavior
The Rhea is a moderately sized ratite that originates in South America. The chicks are often raised on farms because, like the ostrich, Rheas are useful to humans for meat, hide and feathers.
Rheas are social birds, congregating in flocks of up to thirty individuals. The flocks make their homes in brush-covered areas near water, as Rheas enjoy swimming. During the mating season, the male builds a nest by forming a shallow hole in the ground and filling it with dry grass. He then leads several females to the nest, where they each lay an egg in turn. This process may be completed several times and one nest can have as many as thirty eggs. The females then leave and the male incubates and cares for the chicks himself. Like other ratites, Rheas can run quite quickly but cannot fly.
Origin
