The Psittaciformes form an order of birds Tropical known, for example, under the generic terms of parrots , parakeets , lories and conures , these terms also designates particular species. They have marked bold and quite homogeneous allow easy identification. In intelligence recognized, some species are capable of vocalizations remarkable and imitate the human voice. Because of these characteristics and their colorful plumage , many species are reared as pets including some rare and protected, subject to traffic important. Each eye is independent. They have a very mobile neck that allows them a very wide field of vision. Their legs zygodactyles , logical for the most arboreal birds are short. All psittaciformes to help their beaks to move in the trees. They also help their paws to feed or grasp objects they want to get their beaks. One species steals it, the kakapo . Even for migrant psittaciformes over long distances, it appears that these species suffer little when kept in an aviary big enough when they can climb and do acrobatics. The Amazons , for example, travel longer distances, climbing and running in the wheel, even in large aviaries. The Psittacidae animals are gregarious . They spend a lot of time to maintain their plumage but they do that when they feel safe, while stress inhibits this behavior. Many species must drink regularly. In arid regions, the birds are found in groups of thousands of individuals of the same species around water points where they bathe also. Species in tropical rainforests spread their wings when it rains. When the rains are rare species such as budgerigars rub against the morning dew. Psittaciformes, with Corvidae , are considered among the most intelligent birds . The ratio between body mass and brain mass is comparable to that of these species apes , yet their cerebral cortex is relatively small, while it is supposed to be the main area of origin of intelligence . Several studies have been conducted to assess their intelligence, specimens of gray Gabon named Alex and N'kisi are famous . These studies suggest that the gray parrot is indeed an animal intelligence comparable to that of a dolphin or an ape. Indeed, it can recognize shapes, colors, materials, and association. It can happen to converse with a parrot with a form of training called model-rival, involving two people, including the trainer. Alex has a vocabulary that is around 800 words . Gray parrots are able to choose the right words in different contexts, to invent new combinations of words, etc.. Some species of parrots like the Kea are also highly skilled at using tools and solving puzzles. Psittaciformes include not only the crows and woodpeckers to the birds with the highest intelligence. Parrots are in Europe, especially as sprachgelehrige pets known, many experts believe the parrot talking parrots but for a behavioral disorder. Recent research such as the scientist Irene Pepperberg show that not only parrots parrot, but also significant in relation to speak. On most talented here are the Amazons, macaws from South America, Australian cockatoos and African gray parrot. Their intelligence is compared with that of monkeys, but still remains doubtful.
