Satiety in Numbers

Ever wonder why wolves, unlike most carnivores, hunt in packs?

WOLVES—unlike nearly 90 percent of all carnivores—hunt in packs, a behavior that’s long puzzled scientists who say that a single wolf can easily take down a prey animal. Now biologists studying wolves on Michigan’s Isle Royale may have an answer: ravens. These scavengers—which can show up within a minute after wolves kill a moose—steal nearly 40 percent of the carcass from a pair of wolves, while a pack loses just 17 percent of its kill.
