It depends on the vet,some are more expensive than others.I was amazed the other week when my tiel got scared by a cat while out in the aviary and got a few scrapes, it was Sunday afternoon and only an emergency vet available.I was expecting a hugh bill and she only charged me £18.How good was that.She was also telling me about her own parrots who she rescued and was very confident and calm while checking Cracker out.I was impressed.Not least by the cost.my own avian vet charges about £150 for routine blood work.
