Steller’s sea eagles (Haliaeetus pelagicus) are large, powerful birds of prey that primarily feed on fish and water birds. While there is no specific mention of Steller’s sea eagles consuming hawks in the provided search results, it is mentioned that they eat a variety of birds, including ducks and gulls.
Steller’s Sea Eagles and Their Diet
Steller’s sea eagles are native to the far eastern coasts of Russia, particularly the Kamchatka Peninsula, and migrate to Japan and Korea during the winter months. They are considered the most powerful and aggressive of their cousins, the bald eagle and the white-tailed sea eagle. Their diet consists mainly of fish, particularly salmon and trout, but they also eat crabs, shellfish, squid, small animals, and carrion.
Hunting Behavior
Steller’s sea eagles are known to hunt from a perch or while flying, diving to clutch prey in their talons or standing in shallow water to grab passing fish. They are opportunistic feeders and will take advantage of any available food source.
Physical Characteristics
In terms of physical characteristics, Steller’s sea eagles have a wingspan of up to 8 feet (2.5 m) and weigh between 13 to 20 lbs (6 to 9 kg). They are characterized by their dark brown or black bodies with white tail, shoulders, rump, thighs, and forehead.

While there is no specific data on Steller’s sea eagles consuming hawks, it is possible that they may do so if the opportunity arises, given their aggressive and opportunistic feeding behavior. However, their primary focus is on fish and water birds.
Potential Factors Influencing Prey Selection
Several factors may influence the prey selection of Steller’s sea eagles, including:
-
Availability of prey: If hawks are present in the same habitat as Steller’s sea eagles, they may be considered as potential prey, especially if other preferred food sources are scarce.
-
Size and vulnerability of prey: Steller’s sea eagles are known to target smaller and more vulnerable prey, and some hawk species may fall within their preferred size range.
-
Hunting strategy and opportunity: If a Steller’s sea eagle encounters a hawk in a situation where it can successfully capture and consume it, it may do so, but this may not be a common occurrence.
Comparison to Other Eagle Species
While Steller’s sea eagles are known to be aggressive and opportunistic hunters, their diet is primarily focused on fish and water birds. In comparison, some other eagle species, such as the golden eagle, are known to prey on a wider range of birds, including hawks and other raptors.
Conclusion
In summary, while there is no specific evidence that Steller’s sea eagles regularly consume hawks, it is possible that they may do so if the opportunity arises. However, their primary diet consists of fish and water birds, and they are not known to actively hunt hawks as a significant part of their feeding behavior.
