Martial eagles, one of the largest and most powerful birds of prey in Africa, have been known to eat roadkill as part of their diet. However, their diet primarily consists of mammals, birds, and reptiles, with mammals being the most preferred.
Do Martial Eagles Eat Roadkill?
Yes, martial eagles do eat roadkill, but it is not their primary food source. These birds are opportunistic feeders and will take advantage of any available food source, including carrion found on the side of the road.
Martial eagles are known to hunt and kill animals as large as small antelopes and flamingos, but they will also scavenge for food when the opportunity arises. Eating roadkill can be a valuable source of food for these birds, especially during times when their preferred prey is scarce.
Martial Eagles’ Preferred Prey

While martial eagles will eat roadkill, their diet primarily consists of mammals, birds, and reptiles. In Tsavo East National Park, bateleurs, which are similar to martial eagles in body mass and predatory prowess, were found to rely primarily on Kirk’s dik dik for food, with their diet overlapping 66% in prey species and 72% in prey weight with tawny eagles.
Here is a table of the most common prey items for martial eagles:
| Prey Type | Percentage of Diet |
|---|---|
| Mammals | 60% |
| Birds | 30% |
| Reptiles | 10% |
As the table shows, mammals make up the majority of the martial eagle’s diet, with birds and reptiles making up smaller portions.
Scavenging Behavior in Martial Eagles
While hunting is the primary way martial eagles obtain their food, they will also scavenge for food when the opportunity arises. This includes eating roadkill, which can be a valuable source of food for these birds, especially during times when their preferred prey is scarce.
Young martial eagles, in particular, may rely on scavenging roadkill as they learn to hunt and become more proficient hunters. This is because hunting proficiency takes several months to develop, and young eagles may not have the skills or experience necessary to successfully hunt live prey.
Factors Affecting Martial Eagles’ Diet
Several factors can influence the diet of martial eagles, including:
-
Prey availability: The availability of their preferred prey, such as mammals, birds, and reptiles, can impact the frequency with which they scavenge for roadkill.
-
Habitat: The type of habitat in which the martial eagles live can also affect their diet. For example, in areas with more open landscapes, they may have an easier time spotting and hunting their preferred prey.
-
Competition: The presence of other predators in the same area can also influence the martial eagles’ diet, as they may need to compete for resources or scavenge more frequently.
-
Breeding season: During the breeding season, martial eagles may need to consume more food to support their energy needs and the needs of their young, which could lead them to scavenge more frequently.
Conclusion
In conclusion, while martial eagles primarily feed on mammals, birds, and reptiles, they will also eat roadkill when the opportunity arises. This is especially true for young eagles, who may rely on scavenging as they learn to hunt and become more proficient predators. The frequency with which martial eagles scavenge for roadkill can be influenced by a variety of factors, including prey availability, habitat, competition, and breeding season.
