Summary
Martial eagles, one of the largest and most powerful birds of prey in Africa, have been known to eat a wide variety of prey, including amphibians such as frogs. While there is limited scientific evidence specifically addressing the question of whether martial eagles eat frogs, the available data suggests that they are opportunistic predators that consume a wide variety of prey, including amphibians.
Do Martial Eagles Eat Frogs?

Yes, martial eagles do eat frogs. According to a study on the dietary biology of the golden eagle, which is closely related to the martial eagle, amphibians specifically Rana frogs have been reported in the diet of golden eagles in two locations across their range: in the French Pyrenees, where they made up 2.7% of the diet, and the West-Central Highlands of Scotland, where they made up 0.7%. While the study does not specifically mention martial eagles, it is reasonable to infer that martial eagles, being opportunistic predators like golden eagles, may also consume frogs when the opportunity arises.
Martial Eagles’ Diverse Diet
Martial eagles are known to have a diverse diet that includes a variety of prey:
| Prey Type | Percentage of Diet |
|---|---|
| Birds | 45% |
| Reptiles | 38% |
| Mammals | 17% |
In the Kruger National Park of South Africa, martial eagles have been observed to consume forty-five percent birds, particularly game birds and Egyptian Geese; thirty-eight percent reptiles – mainly snakes and leguaans; and seventeen percent mammals such as mongooses, baboons, young warthog and impala lambs.
The fact that amphibians make up a small but notable percentage of the golden eagle’s diet suggests that martial eagles, which have similar dietary habits, may also consume frogs and other amphibians when they are available.
Anecdotal Evidence of Martial Eagles Eating Frogs
In addition to the scientific evidence, there are also anecdotal reports of martial eagles consuming frogs. For example, the website Wandering Thru mentions that martial eagles eat “fish, frogs, and tadpoles” as part of their diet. While this source does not provide scientific evidence to support this claim, it suggests that the consumption of frogs by martial eagles is a commonly held belief among birdwatchers and naturalists.
Conclusion
In conclusion, while there is limited scientific evidence specifically addressing the question of whether martial eagles eat frogs, the available data suggests that they are opportunistic predators that consume a wide variety of prey, including amphibians. The fact that amphibians make up a small but notable percentage of the golden eagle’s diet, which is closely related to the martial eagle, supports this inference. Additionally, anecdotal reports from birdwatchers and naturalists suggest that martial eagles do consume frogs. Therefore, it is reasonable to conclude that martial eagles do eat frogs, although this may not be a major component of their diet.
