The Common Raven is often a scavenger, but its beak is not strong enough to tear through the thick hide of a winter-killed deer. What clever trick does it often use to get at the nutritious flesh inside?
To get through the tough hide of a dead deer, ravens use a wonderful example of cooperative hunting. The raven that finds the deer will call loudly, attracting other ravens. As the mob gathers, they start making distress calls. That usually attracts a large predator, such as a wolf or coyote. They wait until the predator tears into the carcass. At that point, 3 or 4 of them will start harassing the predator, keeping its attention, while the other ravens steal parts of the carcass. They then share what they get with the ravens that kept the predator busy.
