But what do we really know about this remarkable species? In this article, we’ll explore the fascinating world of Steller’s Sea-Eagle to discover its habits, habitat and conservation status.

Steller’s Sea-Eagle was first discovered by naturalist Georg Wilhelm Steller during his early 18th century expedition to Alaska. It is one of the largest eagles in the world, with a wingspan that can reach up to 8 feet wide! The bird is mainly found in coastal areas of Russia’s Far East and Japan, where it feeds on salmon, herring and other fish. During winter months they migrate south to warmer regions such as Korea and China.

Steller’s Sea-Eagle remains endangered due to human activities such as hunting and illegal egg collecting. Conservation efforts are underway to help protect this majestic species from extinction. In this article, we’ll take a closer look at how conservationists are working hard to protect Steller’s Sea-Eagle and its future in our environment.


Steller’s sea-eagle is a large species of seabird found in northeastern Asia. It has a wingspan of up to 2.45 m, making it one of the largest eagles in the world. The adult has black feathers on its head, neck and chest, with white feathers on its back and tail. Its feet are yellow and its eyes are dark brown. It has a hooked beak that it uses to catch fish and other small prey.

The diet of Steller’s sea-eagle consists mainly of fish, but they also eat birds, crustaceans and small mammals. They hunt by soaring above the water or perching on cliffs or trees near the shoreline. They typically nest near rivers or lakes with plenty of fish to feed on. With their impressive size and strength, they have few predators in their range.

Steller’s sea-eagle is an impressive species that can be found in northeast Asia. Now let’s take a look at its geographic range.

Geographic Range

The Steller’s Sea-Eagle is an impressive bird of prey with a wide distribution range. In spite of this, it has been classified as ‘Vulnerable’ on the IUCN Red List. This classification is often thought of as unfair, given the eagle’s wide geographic reach and population size. To better understand the conservation status of the Steller’s Sea-Eagle, let’s take a look at its range:

  • The species can be found in several countries in East Asia, including:
  • China
  • Japan
  • North and South Korea
  • It also inhabits parts of Russia and coastal areas near the Sea of Okhotsk.

These eagles will migrate south to warmer climates when winter arrives and return to their breeding grounds in spring. In some cases, they have been observed traveling up to 4500 kilometers for the winter season. This incredible ability to move vast distances helps them find food sources during times of scarcity or extreme weather conditions. Moreover, it allows them to inhabit different ecosystems around their home range and possibly adapt better to changing environmental conditions.

Steller’s sea-eagle lives in the coastal regions of eastern Russia, as well as along the Japanese coast. They prefer to inhabit estuaries, bays and islands close to the sea. It has also been known to live in rivers and lakes further inland.

This species of eagle can tolerate a wide range of temperatures, from -50° Celsius to +35° Celsius. They typically build their nests on tall trees near water so they can have access to both fresh water and food sources. During winter months, they migrate southward towards warmer climates.

The next section will discuss diet and hunting strategies of Steller’s sea-eagle.

Diet And Hunting Strategies

Magnificently soaring through the skies, the Steller’s sea-eagle is a powerful predator. Its diet is mainly comprised of fish, such as salmon and herring, which it captures with a seemingly effortless swoop. It also feeds on other animals including seabirds, crabs and shellfish. To catch its prey, this raptor uses a range of hunting tactics.

The Steller’s sea-eagle will often hunt from heights of up to 100 metres in the sky and then dive down to grab its food from the water below. It also hovers over shallow bays or rivers searching for prey before descending rapidly with talons outstretched to seize its meal. The eagle may also circle low over rivers and estuaries waiting for unsuspecting fish to rise to the surface where they can be easily captured by this formidable hunter.

The Steller’s sea-eagle has an impressive wingspan of up to 2 metres, allowing it to soar majestically above its hunting grounds and strike quickly when necessary. This majestic bird is truly a sight to behold as it gracefully glides in search of its next meal. Transforming into an unstoppable force as it plummets towards its target, the Steller’s sea-eagle is an incredible hunter that plays an essential role within its habitat. With these impressive skills, this bird will soon be ready for breeding season.

Breeding Habits

Steller’s sea-eagle breeds during the winter, usually between December and March in Japan. They build their nests in tall trees near rivers, as they are dependent on fish for food. The nest is made of sticks and lined with grass, and can reach up to 1.5 meters in diameter. Pairs will typically lay two eggs but only one young survives the fledging period. Both parents share responsibilities when raising the young eagle, from feeding to defending against predators.

The period between hatching and fledging is about 8 weeks, during which the young eagle will remain close to the nest before eventually taking its first flight. Once it has left the nest, it will stay with its parents for some time before gaining independence and dispersing away from its original home range. With this transition into physical characteristics, we can further explore how Steller’s sea-eagle has adapted to its environment.
