Birds are listed under the exceptions.
Did you know about the ordinance requiring a permit prior to moving in? I think you should pursue the required permit(s) as you say you're doing and take whatever steps necessary to resolve your personal situation. "Other people do it!" isn't going to get you anywhere.
I watched the video and read your response here. I believe that you take care of your snakes and I believe that you love them. I think everyone who's posted here feels that way. Have you tried putting together some kind of petition? Maybe if you go to your neighbors and have a face to face discussion with them about what the snakes mean to you, how you're prepared to make sure they don't pose a threat to the neighbors, and give them an opportunity to ask you questions, maybe you can get enough people to back you that the city will give you the permit you need and the whole thing will be resolved.
I really don't think anyone here wants to see you lose your snakes, and no one has said that you should. The general consensus is just that no one is above the law, even a fellow enthusiast.
