Budgerigar (Melopsittacus undulatus), a popular parakeet.—Bruce Coleman Ltd.

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.
