As a caged bird, cockatiels are second in popularity only to the budgerigar. The cockatiel is the only member of the genus Nymphicus. It was previously considered a crested parrot or small cockatoo; however, more recent molecular studies have assigned it to its own subfamily, Nymphicinae.t 30 to 33 cm (12â13 in), the cockatiel is the smallest of the cockatoos which are generally larger at between 30 and 60 cm (12â24 in).
