Parrot Novices often confuse the cockatiel with the cockatoo because of the similarity in names. However, aside from crests and a powdery down, the two species have little in common. While some find the beautiful cockatoo too loud and demanding to keep, the mild little cockatiel (Nymphicus hollandicus) is an excellent choice for most people who would like to own a parrot. In fact, the cockatiel challenges the budgie as most popular pet parrot in the United States, according to the American Pet Products Manufacturers Association. The normal cockatiel is mostly grey, with a few white flight coverts and bright orange-red ear patches. Mature males have almost completely yellow heads. Attractive color mutations include pied, cinnamon and lutino. 

Country of origin: Australia. Size: Small and slender with long tail. Almost twice the size of a budgie at 12.5 inches long, but only 90 grams (a little over three ounces). 

Personality: Even-tempered, affectionate, and inquisitive but not an acrobatic parrot like some. Gentle, gregarious, playful. Chatters and scolds but voice is not loud compared with larger parrots. Crest stands erect when alarmed or interested. Unlike many parrots, which become nippy or difficult to handle as they get older, tamed cockatiels remain mellow, making them an excellent choice for children. The Britney Spears of parrots, cockatiels possess cheerful, musical voices; however, they can scream shrilly for attention. Must be protected from larger or more aggressive parrots. 

Talking ability: Poor to moderate. Can develop large vocabulary but high raspy voice may not enunciate well.

Average lifespan: 15-20 years.
