Buffalo is an ambiguous tag floating out there with about 100 posts and no implications that can either refer to bison or the various true buffalo. This could be made a paraphyletic umbrella tag (like fox currently is), but I think disambiguation is better, as bison and true buffalo look quite different from one another.

African buffalo has been aliased to Cape buffalo, one of its subspecies, for some reason, which is also implied directly to bovine at the moment rather than true buffalo as it should be: https://en.wikipedia.org/wiki/African_buffalo | https://en.wikipedia.org/wiki/Bubalina

I think aliasing Cape buffalo away is fine, bc most of the African buffalo subspecies aren't very visually distinct (The African forest buffalo is the exception, to the point where some consider it a separate species).
