Stellers Sea Eagle, also known as Stellers Sea Eagle in English, is a large bird of prey with two subspecies.
The Steller's Sea Eagle has only one named subspecies in China, which is extremely rare and has only been recorded in Luannan, Hebei, Yuci, Shanxi, Dalian and Yingkou, Liaoning, Hunchun, Jilin, Fuyuan, Heilongjiang, and Hsinchu and Chiayi, Taiwan. Except for Taiwan, where the bird is a stray, the residence situation in other places is also unclear. Jilin and Liaoning may be summer migrants, Hebei may be winter migrants, and Shanxi may be migratory birds.
Most Steller's sea eagles migrate south to Japan's Kuril Islands and Hokkaido to overwinter when winter comes.
Steller's sea eagles fly slowly, often gliding, circling in the air, or standing on rocky shores, tree branches, or sand dunes on the shore for a long time. In winter, they move in groups, often gliding and circling in the sky, and their movements are extremely alert. In winter, they move in groups. They are the largest birds of prey in the sky over the bay. They have alert eyes and pay attention to the movements of prey at any time. They are agile and often hit the target with one strike. When hunting, Steller's sea eagles will hover 6-7 meters above the water or wait in shallow water.
The main food of Steller's sea eagles is fish, especially salmon and trout. In addition to fish, they sometimes hunt some birds and mammals, and also eat carrion. They also hunt young seals. Although few people have studied their foraging habits, their food is roughly the same as that of their close relatives, the bald eagle and the white-tailed sea eagle. However, unlike the fishing eagle and the osprey, which are more specialized in their diet, they also eat large and medium-sized birds such as wild ducks, geese, and swans, and small and medium-sized mammals such as hares, mice, and foxes, as well as crustaceans, baby seals, and the carcasses of fish, sea beasts, etc.
The call of the Steller's sea eagle is deep and hoarse, which can remind people of the roar of a tiger; the hoarse bark is kyow-kyow-kyow; when fighting for food or resting, it makes a strong kra, kra, kra, kra call.
