Only a small percentage of vets in the AAV are board-certified, so I'd start my search here:

I have two vets, Jose Biaschoechea in Mt Pleasant SC, who is one of the newest diplomates, and Rhoda Stevenson in Jacksonville, FL, one of the first group to achieve that status, now 20 years ago. Rhoda's hospital, Exotic Bird Hospital is fabulous, and she has three full time avians-and-exotics-only vets on staff with 24/7/365 emergency vet on call, who will, if need be, open the hospital for you at any time. (Including Christmas Eve: I had a beak bleed I couldn't get stopped and called her close to 6 p.m. on Dec. 24th, and she was willing to be there if we had to go there.
