Tawny eagles are opportunistic hunters that feed on a wide variety of prey, both live and carrion, during the winter months. Their diet includes mammals, birds, reptiles, fish, amphibians, and insects, making them highly adaptable predators.
Tawny Eagles’ Winter Diet
In the winter, tawny eagles in Africa have been observed feeding on the carcasses of ungulates, such as antelope. They are skilled hunters, using a variety of techniques to capture their prey, including:
- Short dives or pounces from a perch
- Stooping from high in the air during soaring flights
- Hunting in pairs during the breeding season to secure larger prey
In the Indian subcontinent, tawny eagles prefer to hunt from perch trees like Vachellia nilotica, Prosopis cineraria, and Capparis decidua. They may also forage by walking on the ground and occasionally take birds in the air, with their avian prey ranging from speckled pigeons to flamingoes.
Nocturnal Hunting and Scavenging
Tawny eagles have also been observed preying on nocturnal animals, such as genets and springhares, in areas where they can avoid being killed by traffic at night. They have been seen drinking and bathing at night, suggesting some degree of nocturnal activity and subsistence behavior.
Additionally, tawny eagles are known to attend grassfires in India, presumably to capture any displaced creatures.
Habitat Preferences and Prey Diversity

In southern Africa, tawny eagles are mostly found in thornveld habitats and prefer stands of Acacia trees. In India, they use similar habitats but may also be found in manmade areas, such as arable lands, roadsides, dams, farmland, cattle pastures, and game areas, if feeding opportunities are present.
Tawny eagles have a highly variable diet and are known to eat more than 200 species, including both live prey and carrion. They are capable of taking prey ranging in weight from under 63 g (2.2 oz) to over 4 kg (8.8 lb), with most prey weighing between 0.5 to 1 kg (1.1 to 2.2 lb).
Prey Species Consumed by Tawny Eagles in Winter
Tawny eagles are known to feed on a diverse range of prey species during the winter months, including:
| Prey Type | Examples |
|---|---|
| Mammals | Hares, dikdiks, rodents |
| Birds | Francolins, bustards, hornbills |
| Reptiles | Lizards |
| Fish | Various species |
| Amphibians | Various species |
| Insects | Termites and other insects |
In addition to hunting their own prey, tawny eagles are also known to pirate food from other birds of prey, particularly during the breeding season when they hunt in pairs.
Adaptations for Winter Hunting
Tawny eagles have several adaptations that allow them to be successful hunters during the winter months:
- Keen Eyesight: Tawny eagles have excellent eyesight, which helps them spot prey from a distance and execute precise hunting maneuvers.
- Powerful Talons: Their strong, sharp talons enable them to capture and subdue a wide range of prey, from small rodents to large ungulates.
- Versatile Hunting Strategies: Tawny eagles employ a variety of hunting techniques, including diving, pouncing, and soaring, to adapt to different prey and environmental conditions.
- Opportunistic Feeding: Their willingness to scavenge and feed on carrion, as well as hunt live prey, allows tawny eagles to take advantage of various food sources during the winter.
Conclusion
Tawny eagles are highly adaptable predators that thrive during the winter months by exploiting a diverse range of prey, both live and carrion. Their hunting strategies, habitat preferences, and prey diversity allow them to successfully navigate the challenges of the winter season and maintain their populations across their range.
