Dr. Heidi Hoeffer - board-certified avian specialist. Dr. Hoefer has been treating exotic pets exclusively since 1988. I live in Manhattan and don't drive, but If I did I would be seeing her. I have never seen her in person, but I have heard excellent things about her. I have also read some of her publications that deal specifically with pigeon problems - she seems extremely knowledgeable about pigeons.

Sorry I can't help with finding you a Vet I know a few guys have used vets here on the Island with poor results since most Vets here don't have a clue when it come to pigeons. What's wrong with your birds that your looking for a vet?
They would get sick and the next day they would die. None of these birds were bred in my loft. Now the birds are fine. I an treating for respitory just in case because that is the only thing I did not try.
