Steller’s Sea Eagle is one of the largest eagles on the planet. They have black and brown feathers and a strongly arched yellow bill. Their talons are ideal for grasping onto slippery fish. The feathers on their shoulders, tail and legs are white. The female is typically a third larger than the male.
Steller’s form monogamous pairs which means that they mate for life. The parent pair build nests called “aeries” high up on trees. The aeries are very large nests constructed from twigs and branches, they can be well over 2 meters wide. When parents return to their nests each year, they will add additional branches to their nests for repairs. This can make the nests bulky and very heavy, which can often result in the nest eventually collapsing. The female typically lays 1-3 eggs which require an incubation of <45 days. Then the chicks are born they have much duller colorings than the parents
This species faces many threats as a result of human activity. Their habitats are altered by the logging industry and costal developments. Their food sources are decreased by over fishing as well as hydroelectricity dams on rivers which interfere with the movement of fish. Industrial pollution can contaminate the water from which they source food.
