White-tailed eagles (Haliaeetus albicilla) are the largest raptors in the Baltic Sea area and are known for their powerful hunting abilities. While they are not typically a threat to pets or humans, they can pose a danger to other wildlife, particularly during the winter months.
Hunting Capabilities of White-Tailed Eagles
White-tailed eagles are opportunistic predators and will take advantage of any situation that presents itself. They are capable of attacking large prey of considerable sizes, including dabbling ducks and geese. However, their success rate is somewhat lower than other predators, as healthy mallards and geese are difficult for white-tailed eagles to catch in flight due to their speed and agility.
During the winter months, swans may find themselves at risk if they are forced to land on ice due to their bulk, making them vulnerable to white-tailed eagle attacks. White-tailed eagles also tend to favor the most seasonally abundant prey, including carrion, and will target injured, sick, or dying waterfowl when hunting.
Threats to Other Wildlife

While white-tailed eagles are not typically a threat to pets or humans, they can pose a danger to other wildlife. They have a broad and varied diet and will attack other birds of prey, particularly when the victims are distracted or injured.
Studies have shown that there are no quantifiable negative effects on other wildlife populations due to the presence of white-tailed eagles. However, their opportunistic hunting behavior and ability to target vulnerable prey can still pose a threat to certain species.
Human-Related Factors
Human-related factors, such as lead poisoning and accidents related to human activity, are significant mortality factors for white-tailed eagles. Lead poisoning is a particular concern, as it can cause serious health problems and death in these birds. Scavenging behavior exposes white-tailed eagles to lead from spent ammunition, making them particularly vulnerable to this type of poisoning.
In addition to lead poisoning, white-tailed eagles are also at risk of accidents related to human activity, such as collisions with power lines or vehicles. These human-related factors can have a significant impact on the overall population of white-tailed eagles.
Conclusion
While white-tailed eagles are powerful predators, they are not typically a threat to pets or humans. However, they can pose a danger to other wildlife, particularly during the winter months when swans and waterfowl are more vulnerable. Human-related factors, such as lead poisoning and accidents related to human activity, are significant mortality factors for these birds and can have a significant impact on their overall population.
