A reference overview
The cockatiel (Nymphicus hollandicus), also known as the weero/weiro or quarrion, is a species of small- to medium-sized parrot belonging to the cockatoo family (Cacatuidae), of which it is the smallest member. Native to Australia, it is the sole member of the genus Nymphicus. Cockatiels are widely recognized for their expressive crests, long tail feathers, and sociable, playful nature, and their strong affinity for human interaction has made them among the most commonly kept companion parrots worldwide and one of the five most popular pet bird species; an estimated 4.8 million US households keep them.
