While some antics of the natural world may seem less than honorable (Ben Franklin suggested the turkey, remember), these antics have been going on longer than we have been around to judge.
I used to spend a good deal of time watching the fall southern rapture migration. I did not see it but know someone that saw a golden eagle snatch a redtail in midair. Normally that would never happen. In fact, some so called expert's scoffed at the act. The strong survive.
