an early age; however, they only rarely develop into competent talkers. Macaws can also be considered to be good talkers as well. Amazon parrots Many species of the genus Amazona are talkers, including the yellow-headed amazon (Amazona oratrix), yellow-crowned amazon (Amazona ochrocephala), yellow-naped amazon (Amazona auropalliata), blue-fronted amazon (Amazona aestiva), white-fronted amazon (Amazona albifrons), lilac-crowned amazon (Amazona finschi), orange-winged amazon (Amazona amazonica), Panama amazon (Amazona ochrocephala panamensis) and mealy amazon (Amazona farinosa). They tend to relate sounds to relationships more than the grey parrots, and therefore outperform the grey parrots in more social environments. Grey parrots The African grey parrots (Psittacus) are particularly noted for their advanced cognitive abilities and their ability to talk. There are two commonly kept species of which the Timneh parrot (Psittacus timneh) tends to learn to speak at a younger age than the Congo parrot (Psittacus erithacus). Pet Congo greys may learn to speak within their first year, but many do not say their first word until 12–18 months old. Timnehs are generally observed to start speaking earlier, some in their late first year. Cockatoos Australian galahs (Eolophus roseicapilla) can talk, although not as well as some other parrots. Male galahs are reportedly easier to teach than females. The yellow-crested cockatoo (Cacatua sulphurea) is rated as a fair-to-good talker. The long-billed corella (Cacatua tenuirostris) is described as being able to talk "very clearly". Parakeets The budgerigar, or common parakeet (Melopsittacus undulatus), is a popular talking-bird species because of their potential for large vocabularies, ease of care and well-socialized demeanor. Between 1954 and 1962, a budgerigar named Sparkie Williams held the record for having the largest vocabulary of a talking bird; at his death, he knew 531 words and 383 sentences. In 1995, a budgerigar named Puck was credited by Guinness World Records as having the largest vocabulary of any bird, at 1,728 words. The monk parakeet (Myiopsitta monachus), sometimes known as the quaker parakeet, is also a skilled talker. The Australian king parrot (Alisterus scapularis) can be trained to talk if it is hand-reared. The Indian ring-neck parakeet (Psittacula krameri manillensis), a subspecies of the rose-ringed parakeet, is an accomplished talker and popular pet which can develop a large vocabulary and talk clearly in sentences. The blossom-headed parakeet (Psittacula roseata) is rare and therefore not often kept as a pet, however, they are good talkers. The African ring-neck parakeet (Psittacula krameri krameri), another subspecies of
