The golden eagle (_Aquila chrysaetos_) is not primarily a scavenger. Although it may occasionally eat carrion during harsh winters, it is predominantly an active predator. Golden eagles hunt small mammals, birds, and fish, with rabbits, hares, ground squirrels, and marmots forming much of their diet. They also prey on grouse, pheasants, ptarmigans, and waterfowl. Using keen vision, powerful talons, and agility, they capture live prey.
