Here's a great time lapse video showing a buck that has died in Texas, and gives you an idea of the circle of life, and what takes place in nature after an animal dies. In this video, you'll see a wide variety of animals that come into play.
The video is from Lone Star Outdoor News --- "Just about every creature in this North Texas ecosystem takes advantage of a buck after it goes down — and Lone Star Outdoor News was there to capture every minute of it. Watch and see just what sort of impact even a dead deer can have on its environment."
