Crested Eagles, also known as Changeable Hawk-Eagles, are known to occasionally consume dead animals, but their primary diet consists of a variety of live prey. These skilled hunters feed on medium-sized birds, mammals, reptiles, and amphibians, with their specific diet varying based on location and prey availability.
Understanding the Crested Eagle’s Diet
Crested Eagles are opportunistic predators, meaning they will take advantage of various food sources, including carrion (dead animals). However, their hunting prowess and preference for live prey make them primarily active hunters rather than scavengers.
Live Prey
Crested Eagles are adept at hunting a wide range of live prey, including:
- Medium-sized birds, such as pigeons, doves, and small waterfowl
- Mammals, including small to medium-sized rodents, hares, and young deer or antelope
- Reptiles, such as snakes, lizards, and small crocodiles
- Amphibians, including frogs and small snakes
These birds of prey use their sharp talons and hooked beaks to capture and kill their prey, often swooping down from a perch or soaring high above the ground to spot their targets.
Carrion Consumption
While Crested Eagles are not primarily scavengers, they may occasionally feed on dead animals they come across. This can include:
- Carcasses of animals that have died from natural causes
- Remains left behind by other predators
- Road-killed animals
Crested Eagles may consume carrion as a supplementary food source, especially during times of prey scarcity or when other hunting opportunities are limited.
Factors Influencing Crested Eagle Feeding Behavior

The Crested Eagle’s diet and feeding habits can be influenced by several factors, including:
-
Habitat and Ecosystem: The specific environment in which a Crested Eagle lives can impact the availability and diversity of prey. For example, those living in forested areas may have access to different prey than those in more open, grassland habitats.
-
Prey Availability: The abundance and distribution of potential prey species can significantly influence the Crested Eagle’s hunting and feeding patterns. If certain prey animals are scarce, the eagle may be more inclined to scavenge or seek alternative food sources.
-
Seasonal Changes: Seasonal variations in weather, migration patterns, and the life cycles of prey species can affect the Crested Eagle’s hunting and feeding strategies. They may adjust their diet and foraging behavior to adapt to these changes.
-
Competition and Predation: Crested Eagles may face competition from other predators, both avian and terrestrial, for access to live prey. In some cases, they may resort to scavenging to avoid direct confrontation with larger or more dominant predators.
Conservation Efforts for Crested Eagles
The Crested Eagle is currently listed as a species of “Least Concern” by the International Union for Conservation of Nature (IUCN). However, this species faces various threats, including:
- Habitat loss and fragmentation due to deforestation, urbanization, and agricultural expansion
- Human persecution, such as hunting and poisoning
- Declining prey populations due to overhunting and habitat degradation
Organizations like The Peregrine Fund are working to conserve Crested Eagles and other birds of prey through scientific research, habitat protection, education, and community development programs. These efforts aim to ensure the long-term survival of this impressive raptor species.
Conclusion
While Crested Eagles are not primarily scavengers, they may occasionally consume dead animals as a supplementary food source. Their diet is primarily focused on hunting a variety of live prey, including medium-sized birds, mammals, reptiles, and amphibians. Understanding the factors that influence their feeding behavior and the conservation efforts aimed at protecting this species is crucial for ensuring the continued survival of the Crested Eagle.
