Most of the time I am in the room, however there have been times when I think the vet prefers to leave the room with the bird depending on what is being done and the equipment needed to do whatever procedure is required. For instance, I have had birds that needed fluid drained from the abdominal area, in that instance the vet left the room with the bird, I think sometimes there are things that the vet thinks are too disturbing for an owner to watch, and does not want to freak out the owner. My vet has a station in the back that is specifically used for nail and beak trims and has various tools available, but there have been times when I have requested that it be done in the room because of the nervousness of the bird and it has not been an issue. I always feel more comfortable if I am right there during any procedure.
