This prey didn't have a prayer. Watch above as a leopard in a tree pounces on an impala in Botswana. In a Sept. 19 blog post at Africa Geographic, Yasmin Tajik explained that the female leopard waited patiently above a group of grazing impala as the animals drifted toward the tree. "We knew we were about to witness a once in a lifetime event," Tajik wrote. While the video might be disturbing to some, it offers a fascinating look at a predator in action.
