It is a very rare species in Korea and, as it is disappearing and requires international protection, is designated and protected as a Natural Monument. The Steller's Sea-Eagle is distributed in eastern Asia, around the Sea of Okhotsk, Sakhalin, the Ussuri region, Korea, Japan, and other areas. Except for its white tail, it is entirely chocolate brown. It is very large, particularly notable for its large bill, distinguishing it from the White-tailed Eagle. It nests on large branches along coasts or on high rocky outcrops of coastal areas. It primarily feeds on fish but also hunts birds and mammals. Morphology: Total length 89-102 cm. It is a very large eagle with a large bill; two subspecies exist. The Dark-bellied Steller's Sea-Eagle is black with white shoulders and tail. The Steller's Sea-Eagle lacks white shoulder patches and is uniformly black except for its white tail. It is distinguished from the White-tailed Eagle by its uniformly dark plumage on the head and neck and its large bill. Juveniles of both subspecies are black overall but generally have white tails. Ecology: It nests on large branches along coasts or on coastal rocky cliffs. It builds large nests by stacking branches, and as it repairs and reuses the same nest annually, the nest becomes larger. It lays 2 pale bluish-white eggs. It inhabits coasts, lower reaches of rivers, plains and mountain rivers, lakes or river banks, mudflats at river mouths and estuaries, and reed-beds. Its call is sharp 'kut, kut, kut' or 'gat, gat, gat'; occasionally it produces a sharp 'kut' sound. It is a globally declining species of worldwide conservation concern. The Dark-bellied Steller's Sea-Eagle is an uncommon winter bird; the Steller's Sea-Eagle is an uncommon resident and winter bird, with the latter being more common among the two subspecies. Some scholars do not recognize subspecies, and restudy of both subspecies is required. This subspecies has 8 collection records from South Hamgyong, South Pyonggan, Kangwon, Gyeonggi Provinces, and recent photographs were taken on January 3, 1988, of one individual perched on a tree at Daseong-dong reservoir, Gunae-myeon, Paju-si, Gyeonggi Province (DMZ). Outside Korea, only one specimen from the Ussuri region is known.
