 And all this meat in one small area attract the scavenger 1, the short-faced bear. Led by his super sensitive nose, his long limbs carry him many miles a day in search of carrion 2. He's picked up a scent 3, 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 4, the bear can crack them open for the marrow 5 locked inside.
 
With water so scarce elsewhere, animals from miles around converge 6 here in the valley, which is good news for the local lions—their pride territory is now overflowing 7 with food.
 
Once the midday heat subsides 8, the females rouse themselves to hunt.
