Steller’s Sea Eagles (Haliaeetus pelagicus) are known for their impressive diving skills when hunting for fish. These massive birds of prey, found in the coastal regions of northeastern Asia, are renowned for their ability to plunge into the water from great heights to catch their slippery prey.

Diving Behavior of Steller’s Sea Eagles

Steller’s Sea Eagles are highly adapted to hunting fish, with sharp talons and a reversible outer toe that allows them to grasp their prey. When hunting, these eagles typically scan the water from a perch, waiting for the perfect moment to strike. Once they spot a fish, they dive towards it, often submerging their entire bodies in the water to capture their target.

According to a study, Steller’s Sea Eagles have been observed diving from heights of 10-30 meters, reaching speeds of 110-120 km/h before hitting the water surface. These powerful birds can dive as deep as 1-2 meters underwater to catch fish.

Cooperative Hunting Strategies

Steller’s Sea Eagles are known to hunt cooperatively, with multiple birds working together to herd fish towards shallow water, making it easier to catch them. During the salmon spawning season, these eagles have been observed gathering in groups of up to 50 individuals to take advantage of the abundant prey.

Migratory Patterns

In addition to their impressive hunting skills, Steller’s Sea Eagles are also known for their long-distance migration patterns. These birds can travel up to 5,000 kilometers between their breeding and wintering grounds, often following the coastline and flying at heights of up to 2,000 meters.

Threats and Conservation Status

Despite their remarkable abilities, Steller’s Sea Eagles face numerous threats, including habitat alteration, industrial pollution, and overfishing, which can decrease their prey source. Currently, these eagles are classified as Vulnerable on the IUCN Red List, with a total population size of around 4,600-5,100 individuals, including around 1,830-1,900 breeding pairs.

Conclusion

Steller’s Sea Eagles are truly remarkable birds, known for their impressive diving skills and powerful hunting abilities. These eagles are highly adapted to hunting fish, with specialized features that allow them to grasp their slippery prey. From their cooperative hunting strategies to their long-distance migrations, Steller’s Sea Eagles continue to captivate and inspire those who study them.
