Wrong. First, the cockatiel is a cockatoo species endemic to Australia. Second, not all cockatoos are white with the yellow crest (see Calyptorynchus and Zanda genera). Third, related to the second point, after the Gang-gang cockatoo split away from the main cockatoo branch, the remaining branch later split into the Galah and the true white cockatoos and corellas.

you had a cockatiel, which is an Australian species. It is a famous bird. And this bird is a Gang-gang cockatoo. Look up. Theyre different species.

I'm pretty sure it's an actor. /joke
