（单词翻译）

 And all this meat in one small area attract the scavenger1, the short-faced bear. Led by his super sensitive nose, his long limbs carry him many miles a day in search of carrion2. He's picked up a scent3, 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 jaws4, the bear can crack them open for the marrow5 locked inside.
 
With water so scarce elsewhere, animals from miles around converge6 here in the valley, which is good news for the local lions—their pride territory is now overflowing7 with food.
 
Once the midday heat subsides8, the females rouse themselves to hunt.
