Glowing eyes of a hungry coyote scan the sky for circling ravens (left). The birds locate carrion, sparing the coyote a random search through deep snow that could leave it foot sore and exhausted. Conversely, in summer ravens often depend on the coyote's leftovers. Here incongruous partners share the remains of a fallen elk (right).Dining mainly on carrion and small animals, the coyote never wastes energy by attacking a healthy, full-grown elk or deer. Unfortunately, it has learned that domestic lambs offer little resistance.
