Eastern imperial eagles are large birds of prey that primarily inhabit mountainous areas with large trees for nesting, but can also be found in open country with scattered trees. They have a wide geographic range, breeding in southeastern Europe and extensively throughout West and Central Asia, with most populations migrating to northeastern Africa, the Middle East, and South and East Asia for the winter.
Do Eastern Imperial Eagles Prey on Other Birds?
Yes, eastern imperial eagles are known to prey on various bird species, especially young or fledgling birds. They have a highly varied prey spectrum that includes small to medium-sized mammals, birds, reptiles, fish, and insects. Their hunting techniques include soaring high above their prey and making a steep dive to seize it with their powerful talons, as well as stalking and flying.
Types of Birds Eaten by Eastern Imperial Eagles
Eastern imperial eagles have been observed preying on a variety of bird species, including:
- Waterfowl (e.g., ducks, geese)
- Gamebirds (e.g., pheasants, partridges)
- Waders (e.g., herons, egrets)
- Gulls and terns
- Corvids (e.g., crows, magpies)
- Pigeons and doves
- Small songbirds (e.g., larks, sparrows)
The specific bird species targeted by eastern imperial eagles may vary depending on their geographic location and the availability of prey.
Hunting Behavior and Techniques

Eastern imperial eagles are known to employ different hunting techniques to capture their prey, including:
- Soaring and Diving: These eagles are skilled at soaring high above their prey and making a steep dive to seize it with their powerful talons.
- Stalking and Flying: They also use a more stealthy approach, stalking and flying low to the ground to surprise their prey.
- Perch Hunting: Eastern imperial eagles may also wait patiently on a high perch, such as a tree or cliff, to spot and ambush their prey.
Their hunting success is aided by their excellent eyesight and their ability to detect prey from a distance.
Breeding and Nesting Habits
Eastern imperial eagles are monogamous and form pair-bonds that last for life. They breed between late March and September, constructing a very large nest of sticks in tall trees, but may also build it in low scrub or on a cliff or ground.
The female lays 2 to 3 eggs and incubates them for 43 days, with both parents participating in the incubation. The eaglets hatch at intervals of several days and are brooded by the female, while the male captures prey. From when the young are 40 days old, the female typically resumes hunting and takes to a perch nearby.
Conservation Status and Threats
Eastern imperial eagles have declined greatly throughout history due to various factors, including:
- Persecution
- Loss of habitat
- Depletion of prey species
- Incidental consumption of poison baits meant for other animals
As a result, the global population of this powerful bird of prey is small and declining, with around 3,500-15,000 individuals or 2,500-9,999 mature individuals. The eastern imperial eagle is currently classified as Vulnerable (VU) on the IUCN Red List.
Conclusion
In summary, eastern imperial eagles are known to prey on a variety of bird species, including waterfowl, gamebirds, waders, gulls, corvids, pigeons, and small songbirds. They employ different hunting techniques, such as soaring and diving, stalking and flying, and perch hunting, to capture their prey. These large birds of prey are monogamous and form pair-bonds that last for life, breeding between late March and September. However, their populations have declined significantly due to various threats, and they are currently classified as Vulnerable on the IUCN Red List.
