Martial eagles are apex predators found throughout sub-Saharan Africa, with a preference for open habitats such as savanna, steppe, semidesert, and scrubby woodlands. They are Africa’s largest eagle, with adults ranging in size from 78 to 96 cm in length, weighing between 3.1 and 6.2 kg, and having a wingspan of 188 to 260 cm.
Martial Eagles’ Varied Diet
Martial eagles have a varied diet, primarily consisting of medium-sized mammals, birds, and reptiles that weigh between 1 and 5 kilograms. However, they have been known to prey on animals much larger than 5 kilograms, including vervet monkeys, baboons, small antelopes, snakes, and monitor lizards. In a study in the Cape Province of South Africa, Cape hares were the dominant prey, making up 50% of all kills. In other areas, martial eagles primarily prey on rock hyraxes.
Estimated Daily Food Intake

The exact amount that martial eagles eat in a day is not explicitly stated in the search results. However, it is mentioned that martial eagles spend much of their day searching for food and can cover hundreds of square kilometres during these flights. Additionally, martial eagles will eat their prey on the ground if they cannot carry it away, returning to feed for up to 5 days.
To put this into perspective, let’s consider the caloric needs of a martial eagle. According to the National Wildlife Federation, a bald eagle, which is similar in size to a martial eagle, needs to consume approximately 1-2 pounds of food per day to meet its energy needs. Given that martial eagles have a similar size and lifestyle to bald eagles, it is reasonable to assume that their daily food intake would be within a similar range.
Factors Affecting Martial Eagles’ Feeding Habits
Several factors can influence the feeding habits of martial eagles, including:
-
Prey Availability: The abundance and distribution of their preferred prey species can affect how much and how often martial eagles need to hunt.
-
Breeding Season: During the breeding season, martial eagles may need to consume more food to support their own energy needs as well as those of their chicks.
-
Environmental Conditions: Factors like weather, habitat, and competition with other predators can impact the ease with which martial eagles can locate and capture their prey.
-
Individual Characteristics: The size, age, and hunting experience of individual martial eagles can also play a role in their daily food intake.
Conclusion
In conclusion, while specific data on the exact amount of food that martial eagles consume in a day is not available, it is clear that they have a varied diet and can consume prey ranging in size from 1 to over 35 kilograms. Based on the caloric needs of similar birds, it is estimated that martial eagles consume 1-2 pounds of food per day, though this can vary depending on a variety of factors.
