Be prepared to pay a bit more than that. I have a cockatoo. Nothing really exotic. Just a white umbrella cockatoo. Had her for 17yrs now.(They live for between 70 and 80 years!) At the beginning of this year there was an identical bird for Sale
complete with large cage in the local pet shop.
It sold pretty fast. Be prepared to fall of your perch here:-
A macaw (big fellows with the long tail and vivid, bright colours) are quite a bit more.
You may get one a bit cheaper direct from a breeder, but I think you would still have to be reeeeeeel friendly with your Bank Manager !!
