释义 | parrot bird ![]() ![]() The African gray parrot (Psittacus erithacus) is unsurpassed as a talker; the male can precisely echo human speech (mimicry). 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 forest (tropical rainforest)s 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. ![]() 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. It runs in the grass, flushes like a quail, and makes a sudden deceptive pitch, and it was formerly hunted with dogs. It eats seeds and insects; its nest is a leaf-lined depression under a bush. ![]() The pygmy parrots of the subfamily Micropsittinae all belong to the genus Micropsitta. The six species are endemic to New Guinea and nearby islands. These are the smallest members of the family. They live in forests, where they eat insects and fungi. ![]() ![]() ![]() Additional Reading General works include Tony Juniper and Mike Parr, Parrots: A Guide to Parrots of the World (1998); David Alderton, The Atlas of Parrots of the World; and the classic Joseph M. Forshaw, Parrots of the World, 3rd rev. ed. (1989), all lavishly illustrated books. Maintaining parrots in captivity is discussed in Rosemary Low, Parrots: Their Care and Breeding, 3rd rev. ed. (1992). Training of parrots is addressed in Sally Blanchard, Companion Parrot Handbook (1999). |
