Large and distinctive dark eagle of forested mountains and hills. Adults appear all dark from a distance, but closer inspection reveals pale barring on the primaries, secondaries, and undertail, as well as a bright yellow bill, and feet. Readily separated from other large birds of prey in range by structure as well as coloration; Black Eagles have broad paddle-shaped wings with distinctive “fingers” that widen out towards the tip, as well as a long tail that is fan-shaped when open and wedgelike when closed. Most often seen gliding effortlessly over woodlands, close to the canopy. Mostly silent except during breeding season when it emits a whistling call.
