Budgerigar

Parakeets are social animals and require stimulation in the shape of toys and interaction with humans or with other budgerigars. Budgerigars, and especially females, will chew material such as wood. When a budgerigar feels threatened, it will try to perch as high as possible and to bring its feathers close against its body in order to appear thinner.

Tame budgerigars can be taught to speak, whistle, and play with humans. Both males and females sing and can learn to mimic sounds and words and do simple tricks, but singing and mimicry are more pronounced and better perfected in males. Females rarely learn to mimic more than a dozen words. Males can easily acquire vocabularies ranging from a few dozen to a hundred words. Pet males, especially those kept alone, are generally the best speakers.

Alternative common names include budgie, shell parrot, warbling grass parakeet, canary parrot, zebra parrot, flight bird, scallop parrot, love bird and the alternate spellings budgerygah and betcherrygah.
