parakeet or parrakeet, common name for a widespread group of small parrots, native to the Indo-Malayan region and popular as cage birds. Parakeets have long, pointed tails, unlike the chunky lovebirds with which they are sometimes confused. The budgerigar, also called the shell, zebra, or grass, parakeet (Melopsittacus undulatus), is the best known of the true parakeets. The wild budgerigar of Australia is usually green or blue with black-and-yellow markings; as a cage bird, however, it has been bred in white and yellow. The hanging parakeet sleeps upside down like a bat.

The extinct Carolina parakeet was the only parrot native to the United States. It was 12 in. (30 cm) long with a yellow-green body and orange-red head. It was sought as a cage bird and for its plumage, and was killed as a destroyer of fruit and grain crops. The budgerigar and other released or escaped nonnative parrots may be found in the United States, mainly in California, Texas, and Florida, but the monk parakeet (Myiopsitta monachus), a green and yellow bird with a pale gray forehead and breast and dark blue wing feathers, has well-established colonies in several northern and southern states.

Parakeets are classified in the phylum Chordata, subphylum Vertebrata, class Aves, order Psittaciformes, family Psittacidae.

Carolina parakeet, small, long-tailed bird, Canuropsis carolinensis, now believed extinct. The Carolina parakeet was the northernmost representative of the parrot family. It had green plumage with a yellow head and orange cheek patches and forehead. The largest specimens were 13 in. (33 cm) in length, including the tail feathers. It was formerly distributed throughout the SE United States, as far north as Virginia and as far west as Texas; the last specimens were seen in S Florida early in the 20th cent. A fruit eater, the Carolina parakeet was an agricultural pest and was therefore exterminated by farmers. It is classified in the phylum Chordata, subphylum Vertebrata, class Aves, order Psittaciformes, family Psittacidae. See parakeet.

Any of 115 species in 30 genera (subfamily Psittacinae) of small, slender seed-eating parrots with a long, tapering tail. Parakeets are found worldwide in warm regions. They typically form large flocks. Most species lay four to eight eggs in a tree hole. The most popular caged parakeet is the budgerigar (Melopsittacus undulatus), mistakenly called lovebird; about 8 in. (19 cm) long, it may be any colour but usually has cheek spots and close barring on the upper parts.
