They were in every Castle Show! They were Stunning! Even in Tomorrowland when Disney Mania played at Galaxy.They're the real deal. I remember reading that they used to release doves each morning in MK until the birds of prey would stop by to get a morning snack between the castle and the dove's landing spot. The everglades are not very far away, as the bird flies...
Is this the same reason MGM Stopped them in BATB?
I wish they could come back in some form.
