Greater Rhea

The Biggest Animals Kingdom and in The World | Greater Rhea | Males are larger than females in general. Large males weighing up to 40 kg (88 lbs), about 1.83 m (6.0 feet) tall and measures approximately 150 cm (59 inches) in length, although this is rare. The head and beak, small enough that measure 8 to 10.4 cm (3.1 to 4.1 inches) in length. Wings rather long Rhea americana, birds use them while working to maintain balance on the tight bends and when coutship screens. Rhea plumage is soft, ragged appearance, which is gray or brown, with a high individual variability, head, neck, trunk and upper legs of birds. Usually the males darker than females. Cub Rhea great with dark gray stripes. Nandu is endemic in Argentina, Bolivia, Brazil, Paraguay and Uruguay. A small population Rhea installed in Germany. At the end of 2000, the population is estimated in seven birds, and in 2001 eighteen birds. Nandu diet consists mainly of deciduous trees, fruits and seeds, especially when the season, but also insects, scorpions, small rodents, reptiles, birds and small. Meals include plants native species and introduced all kinds of bipartite families Amaranthaceae, Asteraceae, Bignoniaceae, cruciferous vegetables, legumes, Labiatae, myrtle, or nightshade family.

Accepted eat cereal or monocots in general. Even the vegetable materials such as hard and prickly thistle tubers or eat with pleasure. How many birds that feed on plant material, hard, grinders, which will help Nandu swallowing food for optimal digestion. It has attracted a lot of shiny objects, metal objects and sometimes ingested or bright. Young people consume more animal matter, than adults. Sometimes the fish will gather in rheas and eat carrion flies, but they are also known to eat dead or dying in the dry season, but not as commonly feed on vertebrates in large quantities. After the large flocks during the winter holidays, freely formed into three groups: men, herds of 2-15 females and a large herd of cattle. This season approaches, males are aggressive towards each other. Then they look for women, calling and raising the front of his body, and the neck feathers straight and curly.

If you have to set the time for the eggs, the male is usually already in the nest and act aggressive when approaching women. He's nest with wings gradually relax and allow you to bend over and put the egg on the edge of the nest. Male Roll the egg in the nest. The men are polygamous, women are serial polyandry. In practice, this means that women move during the breeding season, mating with the male, and the male before they lay eggs. Nests then shared between females can contain up to 80 eggs laid every ten women female coupling rooms about 5 to 10 eggs. However, the average size of the coupling 26-7 eggs from different females. Recent studies have shown that some men use subordinate males to help protect and incubate the eggs. Rhea eggs the size of 130 mm × 90 mm (5.1 inches x 3.5 inches) and weighs 600 grams (21 ounces), the means of communication, so that they are half the size of an ostrich egg. The nest is a simple scrape flat and wide in a hidden place, men sticks, grass and leaves, in the immediate vicinity of the nest to attract a wide strip as similar to reach the neck. All the eggs hatch within 36 hours of each other, even if the eggs in the nest, may have only two weeks.

Natural predators of adult ostriches are more limited with Puma (Puma concolor) and jaguar (Panthera onca). Wild dogs have been known to kill young birds and Caracara (Caracara Plank) with suspected attack young animals. Armadillos sometimes eat ostrich eggs, nests were Armadillo of six bands (Euphractus sexcinctus) or Hairy Armadillo (Chaetophractus villosus) eggs and Rhea were weakened decomposed. Nanda bred in captivity and significant ecological naivete. Classical conditioning of the Great Teen Model Rhea predators, can be prevented, to a certain extent, but the identity of the birds, both bold or timid impact on the success of this type of training. In 2006, the training protocol was Rhea and prevent potential thieves and is designed to determine the care of the animals for release. This type is similar to the emu and ostrich farm in North America and Europe. Times longer rheas are very territorial during the breeding season.
