🦅Steller’s Sea Eagle
Steller's sea eagle, also known as the Pacific sea eagle or white-shouldered eagle, is a very large diurnal bird of prey in the family Accipitridae. It was described first by Peter Simon Pallas in 1811. No subspecies are recognized. A sturdy eagle, it has dark brown plumage with white wings and tail, a yellow beak, and yellow talons. Typically, it is the heaviest eagle in the world, at about 5 to 10 kg, but in some other standard measurements, may be smaller than the harpy eagle and the Philippine eagle. Steller's sea eagle females are bigger than males, as in other raptors.
