ABOUT : The Steller's sea eagle, also called the Pacific sea eagle or the white-shouldered eagle, is a big, nocturnal predatory bird belonging to the Accipitridae family. Peter Simon Pallas was the first to describe it in 1811. Recognized subspecies do not exist.
Haliaeetus pelagicus is the scientific name.
Facts about Steller's sea eagles : The Steller's sea-eagle's dark body, white forehead, shoulders, tail, and thighs, as well as its bright yellow bill, make it easy to identify. It is thought that they are remnants of the glacial past, having developed on the slender northeast Asian coast and just remaining there through several Ice Age cycles, never occurring anyplace else.
Where do Stellar eagles live? The lower parts of the Amur River, the Kamchatka Peninsula, the coastal region surrounding the Sea of Okhotsk, northern Sakhalin, and the Shantar Islands in Russia are all breeding grounds for Steller's sea eagles. In winter, many eagles move to Korea, Japan, and China from their breeding habitats.
Why is it called Steller's sea eagle? Georg Wilhelm Steller, an adventurer and naturalist from the 18th century, is honored by the name Steller's sea eagle. The females of these birds are usually larger than the males, and they have a huge, sharply arched yellow bill.
What do Steller's sea eagle eat? Mostly consisting of salmon and trout, Steller's sea eagles are raptors that feed on fish. When food is scarce, they will even consume the corpses of deer, puffins, fish, and crabs—all sources of protein, dead or living.
Breeding season : With significant fluctuation based on environment and food availability, Steller's Sea-eagles start breeding in late April or early May. Each pair, being solitary nesters, constructs a gigantic stick nest high in a tree or on a cliff, measuring up to 2.5 meters in width and 4 meters in depth. They will return to this nest year after year.
Do Stellar eagles mate for life? Because Steller's sea eagles are monogamous, they form lifelong relationships. Nests called 'aeries' are erected high up on the trees. The nests are composed of twigs and branches, and they can reach widths of well over two meters.
What is the number of eggs laid by Steller's Sea Eagles? Every year, between April and May, the adult breeding female produces one clutch of one to three eggs, usually just two.
HATCHING TIME PERIOD : The chicks hatch after an incubation period of about 39 to 45 days. When they hatch, the chicks are altricial and have whitish-down coverings.
LIFE SPAN : Steller's Sea Eagles typically have a lifespan of 20 to 25 years in the wild. However, some wild individuals have been observed to live up to 30 years.
Steller's sea eagles are rated as vulnerable on the IUCN Red List of Threatened Species because of their limited and diminishing population levels. Russia, Japan, China, and South Korea have laws protecting Steller's sea eagles, and important habitat regions have been turned into nature reserves in both countries.
