Eagles eat mostly fish, which comprises 60 to 90 percent of their diet. In addition to fish, they eat other birds, such as herons, crows, grouses, ducks or gulls, and small mammals. If live food is scarce, they will scavenge for dead animals, including raccoon, deer, chickens and pigs.
Eagles hunt using various methods. They will often perch in trees, so they can spot prey that is swimming below then swoop down and capture it. They will also fly over open water or stand at the water's edge searching for prey. Once a fish is caught, an eagle flies back to a tree to eat its catch or swallows it whole while still in flight.
