Stellar’s sea eagle is one of the world’s heaviest and one of the largest eagles, weighing between 11 to 20 lbs.
Steller’s Sea Eagle: The Colossal Hunter of the Russian Far East – Facts, Size & Conservation
The avian world is home to majestic predators, but few command awe like the Steller’s sea eagle (Haliaeetus pelagicus), one of the largest and heaviest eagles on Earth. With an imposing presence, razor-sharp talons, and wings stretching wider than most humans are tall, this Arctic giant reigns supreme in its remote coastal habitats. Let’s dive into what makes this critically endangered raptor so extraordinary.
Size & Strength: A True Giant of the Skies
When it comes to sheer power, the Steller’s sea eagle is unrivaled:
- Weight: Males weigh 11–15 lbs (5–7 kg), while females dominate at 15–20 lbs (7–9 kg)—making them 20% heavier than bald eagles.
- Wingspan: 6.5–8 feet (2–2.5 meters), enabling effortless glides over icy coastlines.
- Height: Stands up to 3.3 feet (1 meter) tall.
Their distinctive black-and-white plumage, fiery orange beak, and massive “bucket-like” yellow talons make them unmistakable. Adaptations like feathered legs and salt-excreting glands help them thrive in harsh marine environments.
Habitat: Where Do Steller’s Sea Eagles Live?
This eagle calls the remote Pacific coasts of Russia home, nesting in old-growth forests near rivers or sea cliffs. Most populations migrate seasonally to winter in Japan, Korea, and occasionally Alaska, relying on ice-free waters to hunt.
Key Territories:
- Breeding Zones: Kamchatka Peninsula, Sea of Okhotsk, lower Amur River.
- Wintering Grounds: Hokkaido (Japan), Korean Peninsula.
Diet & Hunting: Masters of the Fish Snatch
Steller’s sea eagles are opportunistic carnivores. Their diet revolves around:
- Fish: Salmon, trout, and cod (caught mid-leap or scavenged).
- Waterfowl: Ducks, geese, and even cranes.
- Mammals: Hares, seals, and carrion.
They often steal prey from other birds—a tactic called kleptoparasitism—and rely on salmon runs for up to 85% of their diet in breeding seasons.
Conservation Status: A Species on the Edge
Listed as Vulnerable by the IUCN, fewer than 5,000 individuals remain. Threats include:
- Habitat Loss: Logging and dam construction disrupt nesting sites.
- Overfishing: Depleted salmon stocks starve eagles.
- Pollution/Climate Change: Toxins accumulate in prey; melting sea ice alters migrations.
Conservation groups like the Wildlife Conservation Society and BirdLife International work to protect habitats and regulate fisheries.
Cultural Significance: Japan’s National Treasure
In Japan, the Steller’s sea eagle (called Ō-washi) is revered as a symbol of power and longevity. It draws photographers and birders globally to Hokkaido’s Rausu Coast, where hundreds gather to soar over drift ice—a breathtaking wildlife spectacle.

Q: How long do they live?
A: Up to 25 years in the wild, longer in captivity.
Q: Can I see one outside Russia/Asia?

Final Thoughts: Protecting an Arctic Icon
The Steller’s sea eagle’s survival hinges on global cooperation. Supporting sustainable fishing, habitat preservation, and anti-poaching efforts can ensure future generations witness this feathered titan in flight.
