You are not helping your cause by misnaming the creatures you wish to protect. The only true buffaloes are cape buffaloes and water buffaloes which I believe here in North America are all kept in zoos. If you wish to protect bison, then that's what you should call them and your organization. That is their proper name of which you should be aware. To further promote the misnaming of these animals may be counterproductive. I support the protection of bison but will never support any organization that doesn't use their proper name.
