No Sully can't fly. I believe the last time he flew was when they found him over 8 years ago in the carwash. The pet shop owner clips all her birds so she probably clipped Sully soon after she caught him. But he will get he chance to fly again, I promise that if he can, he will. He has lost some clipped feathers but I have not seen him try to fly yet. But one day he will, I just know it!
