They take advantage of seasonal berries, small mammals, young birds and amphibians and of course are always present to feast on carrion. When food is plentiful, such as is found in the summer, ravens are more spread out and function primarily as predators. A flock of ravens is a good indicator of a predator kill often appearing at the carcass only minutes after the kill. Although smaller than eagles, ravens are often seen harassing both bald and golden eagles and it is not uncommon for a group of ravens to successfully keep these birds away from a carcass. In winter, many snowmobilers have returned from a short hike to find their belongings scattered about the parking lot, with the raven stealing both food and valuables from visitors.
