A bald ealge (Haliaeetus leucocephalus) flies, clutching a mallard duck drake (Anas platyrhynchos) that it caught on Lake Washington near Kirkland, Washington. The mallard is the most common duck in the United States and typically weighs up to 3 pounds (1.4 kilograms). Bald eagles generally weigh between 6 and 14 pounds (3 to 6.3 kilograms) and they are typically capable of lifting up to half of their body weight.
