Nature documentary on scavenger animals in Yellowstone National Park in the United States.
Scavengers in the Yellowstone, home to over 400 species, can gorge on nearly 40 tons of rotting elk during harsh winters. It’s a dirty job, but someone’s got to be nature’s janitors. Casey is setting up a carcass stakeout to discover what happens to all the Yellowstone wildlife after death. Since turkey vultures can smell a carcass up to 12 miles away, he uses them to help him find animal carcasses to observe how they are devoured and by which ravenous creature.
