Steller’s sea eagle (Haliaeetus pelagicus) is the only species of Steller’s sea eagle. It is a large, impressive bird of prey found in the coastal regions of East Asia, particularly in Russia’s Far East, Korea, and Japan. With its striking black and white plumage, massive bill, and impressive wingspan, the Steller’s sea eagle is a true marvel of nature.
The Unique Characteristics of the Steller’s Sea Eagle
The Steller’s sea eagle is the largest of all sea eagles, with a wingspan that can reach up to 2.3 meters (7.5 feet) and a weight of up to 9 kg (20 pounds). Its plumage is predominantly dark brown to black, with striking white patches on the wings, tail, and under-tail coverts. The bird’s large, powerful bill is mostly orange with a yellow tip, and its legs and feet are yellow.
One of the Steller’s sea eagle’s most distinctive features is its diamond-shaped, white tail, which is relatively longer than that of the white-tailed eagle, its closest relative. The eagle’s short, stout toes are equipped with spicules on the bottom, which help it grip slippery fish, its primary prey.
The Steller’s Sea Eagle’s Specialized Feeding Habits

As a specialized fish-eater, the Steller’s sea eagle is often seen plucking fish from the icy seas of its habitat or following fishing boats in search of scraps. Its powerful bill and talons make it well-equipped to catch and consume a variety of aquatic prey, including salmon, trout, and other large fish.
The Steller’s sea eagle’s feeding habits are closely tied to the seasonal movements of its prey. During the summer months, the eagles congregate near salmon spawning grounds, where they can easily catch the fish as they swim upstream. In the winter, the eagles may follow fishing boats or scavenge for food along the coastline.
The Steller’s Sea Eagle’s Limited Range and Conservation Status
The Steller’s sea eagle is found primarily in the coastal regions of Russia’s Far East, particularly the Kamchatka Peninsula, as well as in parts of Korea and Japan. This limited range is due to the eagle’s specialized habitat requirements and feeding preferences.
Despite its impressive size and power, the Steller’s sea eagle is classified as Vulnerable on the IUCN Red List of Threatened Species. Threats to the species include habitat loss, hunting, and the impacts of climate change on its prey populations.
Conservation efforts are underway to protect the Steller’s sea eagle and its habitat. These include monitoring populations, enforcing hunting regulations, and promoting sustainable fishing practices in the eagle’s range.
Conclusion
In summary, there is only one type of Steller’s sea eagle, a unique and impressive species of bird of prey found in a limited range in East Asia. With its striking appearance, massive size, and specialized feeding habits, the Steller’s sea eagle is a true marvel of nature that deserves our attention and protection.
