Any species of Psittacus, Chrysotis, Pionus, and other
   genera of the family Psittacidae, as distinguished from the parrakeets,
   macaws, and lories. They have a short rounded or even tail, and often a
   naked space on the cheeks. The gray parrot, or jako (P. erithacus) of
   Africa (see Jako), and the species of Amazon, or green, parrots
   (Chrysotis) of America, are examples. Many species, as cage birds,
   readily learn to imitate sounds, and to repeat words and phrases.
