If you were an animal, which one would you like to be and why?

When I was a child, I read most all the books available about horses. I would keep my eye on the stallion who barely ate or drank himself. He was the protector of the herd. The wild herds amazed me as I was able to believe my own mind that urged them forward and on to safety.
Yes I agree a bird would be nice too. Although my current preference is Human. I'll let them be free for me to watch another day.
