My mom had to remind my kids (at least a dozen times) while we were in Yellowstone Park last summer, that there are NO buffalo in the US... only bison. Yesh! I thought the names were the same... guess not. Technically, we don't have buffalo in the wild here in the USA... only in zoos. The bison got that term from the settlers who had seen Cape Buffaloes and thought the bison to be a version of that animal. Whatever, right? I will still call them buffalo.
