If you are a hungry Bison calf, your mom is big enough so you don’t have to worry about standing in the middle of the road to get your meal. You can be assured that the cars will just wait until you are done. This calf must be at least three months old because it has developed a darker brown coat. Notice the number 8 branded on the calf’s side. During the annual roundup of the Bison, the new calves are branded with the last digit of the year in which they were born.
