DetailsParrot _Designed by YahooJAPAN ( http://www.thingiverse.com/thing:182240 ) _Parrot, term applied to a large group of gaudy, raucous birds of the family Psittacidae. Parrot also is used in reference to any member of a larger bird group, order Psittaciformes, which includes cockatoos (family Cacatuidae) as well. Parrots have been kept as cage birds since ancient times, and they have always been popular because they are amusing, intelligent, and often affectionate. Several are astonishingly imitative of many sounds, including human speech.The family Psittacidae numbers 333 species. The subfamily Psittacinae, the “true” parrots, is by far the largest subfamily, with members found in warm regions worldwide. These birds have a blunt tongue and eat seeds, buds, and some fruits and insects. Many members of the subfamily are known simply as parrots, but various subgroups have more specific names such as macaw, parakeet, conure, and lovebird. _The African gray parrot (Psittacus erithacus) is unsurpassed as a talker; the male can precisely echo human speech. Captive birds are alert and, compared with other parrots, relatively good-tempered. Some are said to have lived 80 years. The bird is about 33 cm (13 inches) long and is light gray except for its squared, red tail and bare, whitish face; the sexes look alike. Gray parrots are common in the rainforest, where they eat fruits and seeds; they damage crops but are important propagators of the oil palm.Among other proficient mimics are the Amazon parrots (Amazona). The 31 species of Amazons are chunky birds, mostly 25 to 40 cm (10 to 16 inches) long, with slightly erectile crown feathers and a rather short, squared tail. Their predominantly green plumage is marked with other bright colours, chiefly on the upper head; the sexes look alike. Amazon parrots live in tropical forests of the West Indies and Mexico to northern South America. They are difficult to breed and may be aggressive as well as squawky. Common in aviaries is the blue-fronted Amazon (A. aestiva) of Brazil; it has a blue forehead, a yellow or blue crown, a yellow face, and red shoulders. The yellow-crowned parrot (A. ochrocephala) of Mexico, Central America, and from Ecuador to Brazil has some yellow on the head and neck, a red wing patch, and a yellow tail tip. _The monk, or green, parakeet (Myiopsitta monachus) is one of the hardiest parrot species. It is native to South America, but some have escaped from captivity in the United States and now nest in several states. Its large stick nest is unique among psittaciforms. Other remarkable parrots of this subfamily include the hanging parrots (Loriculus), which sleep upside-down like bats. Caiques (Pionites) are small, short-tailed South American birds similar to conures in build and habits.For decades the night parrot, or night parakeet (Geopsittacus occidentalis), of Australia was thought to be extinct, until a dead one was found in 1990. It feeds at night on spinifex grass seeds and dozes under a tussock by day. Its nest is a twig platform in a bush and is entered by way of a tunnel. Equally unusual is the ground parrot, or ground parakeet (Pezoporus wallicus). Rare local populations exist in the wastelands of coastal southern Australia and western Tasmania. _Studies with captive birds have given insight into which birds are the most intelligent. While parrots are able to mimic human speech, studies with the African grey parrot have shown that some are able to associate words with their meanings and form simple sentences . Along with crows, ravens, and jays (family Corvidae), parrots are considered the most intelligent of birds. The brain-to body size ratio of psittacines and corvines is actually comparable to that of higher primates. One argument against the supposed intelligent capabilities of bird species is that birds have a relatively small cerebral cortex, which is the part of the brain considered to be the main area of intelligence in other animals. However, birds use a different part of the brain, the medio-rostral HVC, as the seat of their intelligence. _Humans and parrots have a complicated relationship. Economically they can be beneficial to communities as sources of income from the pet trade and are highly marketable tourism draws and symbols. But some species are also economically important pests, particularly some cockatoo species in Australia. Some parrots have also benefited from human changes to the environment in some instances, and have expanded their ranges alongside agricultural activity, but many species have declined as well.
