Eastern imperial eagles (Aquila heliaca) are large birds of prey that primarily feed on small to medium-sized mammals, such as rabbits and ground squirrels. They also consume reptiles, including some venomous snakes, and other birds, such as young magpies, waders, and ducks. Carrion is also part of their diet. While there is no direct evidence that eastern imperial eagles eat hawks, they are known to prey on a wide variety of animals, and their diet can be quite diverse depending on their habitat and location.
Habitat and Hunting Behavior of Eastern Imperial Eagles
Eastern imperial eagles are found in southern Europe, central and southern Russia, and parts of Asia, including India and China. They prefer open fields or wetlands for hunting and build their nests in isolated tall trees in forests, steppes, open landscapes, agricultural areas, and even semideserts. They are solitary birds, but during migration, they may gather into loose flocks of ten or more.
These eagles are the second largest in Europe, with a length of up to 0.92 meters, a wingspan of up to 2.14 meters, and a mass of up to 3.6 kilograms. They have black-brown feathers, a pale golden crown and nape, and a grey base that extends to the tail. Their juveniles are paler and more variegated, with bolder streaks on their under-wings and body, and they have a larger and more majestic build than other eagles.
Prey Preferences of Eastern Imperial Eagles

Eastern imperial eagles are opportunistic predators that consume a wide variety of animals. Their primary prey includes:
- Small to medium-sized mammals, such as rabbits and ground squirrels
- Reptiles, including some venomous snakes
- Other birds, such as young magpies, waders, and ducks
- Carrion
While there is no direct evidence that eastern imperial eagles eat hawks, their diverse diet and hunting behavior suggest that they may occasionally prey on smaller birds of prey, including hawks. However, this is not a common occurrence, and their main focus is on smaller mammals, reptiles, and other birds.
Comparison with Other Eagles
Compared to other eagles, the eastern imperial eagle is a larger and more powerful bird of prey. They are the second-largest eagle in Europe, after the Spanish imperial eagle (Aquila adalberti). Other notable eagles found in the same regions as the eastern imperial eagle include the golden eagle (Aquila chrysaetos) and the Steppe eagle (Aquila nipalensis).
These eagles have some similarities in their hunting behavior and prey preferences, but they also have distinct differences. For example, the golden eagle is known to prey on larger mammals, such as hares and young deer, while the Steppe eagle is more focused on small mammals and ground-dwelling birds.
Conservation Status and Threats
The eastern imperial eagle is classified as “Vulnerable” on the IUCN Red List of Threatened Species. Their population has declined due to various threats, including:
- Habitat loss and degradation
- Persecution by humans
- Electrocution and collisions with power lines
- Poisoning and hunting
Conservation efforts are underway to protect this majestic bird of prey and ensure its long-term survival. These efforts include habitat management, anti-poaching measures, and the installation of bird-safe power lines.
Conclusion
In conclusion, while there is no direct evidence that eastern imperial eagles eat hawks, they are known to be opportunistic predators that consume a wide variety of animals, including small to medium-sized mammals, reptiles, and other birds. Their diverse diet and hunting behavior suggest that they may occasionally prey on smaller birds of prey, but this is not a common occurrence. Eastern imperial eagles play an important role in maintaining the balance of their ecosystems and are a valuable part of the natural world.
