And all this meat in one small area attract the scavenger, the short-faced bear. Led by his super sensitive nose, his long limbs carry him many miles a day in search of carrion. He's picked up a scent, but where's the carcass? Sometimes the smaller, speedier scavenger gets there first, on this occasion a coyote. Right now the short-faced bear will take whatever he can get. He hasn't had a decent meal in days, and needs at least one good-sized carcass every week to stay alive. This time the coyote's left him nothing but the skeleton. But with his huge, bone-crunching jaws, the bear can crack them open for the marrow locked inside.
