Eastern Imperial Eagles are monogamous and form pair-bonds that last for life. They breed between late March and September throughout their range, engaging in aerial displays and constructing large nests of sticks, which may average up to 1.2 to 1.5 m (3 ft 11 in to 4 ft 11 in) across and 60 to 70 cm (24 to 28 in) in depth. The female lays 2 to 3 eggs and incubates them for 43 days, with the eaglets hatching at intervals of several days.
Breeding Success Rates
The breeding success of the Eastern Imperial Eagle varies across its range:
| Location | Fledglings per Pair |
|---|---|
| Czech Republic | 1.53 |
| Hungary | 1.15 |
| Bulgaria | 1.00 |
| Austria | 1.63 (per successful pair) |
| East Thrace, Turkey | 1.01 |
Prey and Diet
Eastern Imperial Eagles are carnivores and opportunistic predators, with a prey spectrum that includes somewhere between 200 and 300 species. Their diet consists primarily of small to medium-sized mammals, such as hares, various rodents, and insectivores. They also prey on birds, reptiles, fish, and occasionally insects.
Conservation Efforts
The Eastern Imperial Eagle has faced significant declines throughout history due to persecution, loss of habitat, depletion of prey species, and incidental consumption of poison baits. Currently, this species is classified as Vulnerable (VU) on the IUCN Red List, with a small and declining global population. Conservation efforts are crucial to ensure the long-term survival of this majestic bird of prey.
Conclusion
The Eastern Imperial Eagle is a remarkable species, known for its exceptional lifespan of up to 56 years in the wild. Its breeding and nesting habits, as well as its diverse prey spectrum, contribute to its resilience and adaptability. However, the species faces ongoing threats, and conservation efforts are essential to protect this vulnerable bird of prey.
