English budgies and American budgies are all the same species. The English budgies have been selectively bred to look different and the American budgies are more wildtype but they're all the same bird. American budgies are healthier and longer lived because their breeding hasn't tampered with nature so much.
The world record holder for talking parrots is a budgie, with a vocabulary of over 1700 words. And he was an American budgie.
