Bald eagles have sexually monomorphic plumage coloration, although females generally have a somewhat larger body size.
Adult bald eagles are extremely large birds with characteristically yellow eyes and bills, white heads and tails, and dark brown bodies, which may appear almost black.
These birds have extremely large, powerful bodies and large heads, necks, bills, and feet with sharp talons. Generally, their plank-like wings have a span of 178 to 229 centimeters, their bodies are 79 to 94 centimeters long and they weigh about 4.3 kilograms. Their plumage alone weighs about 700 grams, which is twice as much as their skeleton.
