Video by joelsartore/ In addition to being one of the largest eagles in the world, the Philippine eagle is visually striking, with its massive black bill, fringelike leg feathers, and long, brown head feathers. Found on just four islands in the Philippines, this remarkable and critically endangered bird is what researchers call an umbrella species—whose protection leads to the protection of many other species that share the same habitat.
