Martial eagles, the largest eagle species in Africa, are known for their strong territoriality and slow breeding rate. They lay one egg every two years, and the younger sibling rarely survives unless the first egg or hatchling dies. While there are no specific reports of martial eagles abandoning their eggs due to human disturbance, other large eagle species, such as the wedge-tailed eagle, are known to abandon their young due to human disturbance at the nest.
Understanding Martial Eagles and Their Nesting Behavior
Martial eagles are a formidable predator, known for their impressive size and hunting prowess. These birds can grow up to 3.5 feet in length and have a wingspan of up to 8 feet. They are found throughout sub-Saharan Africa, primarily in savannas, grasslands, and open woodlands.
One of the key characteristics of martial eagles is their slow breeding rate. These birds lay only one egg every two years, and the younger sibling rarely survives unless the first egg or hatchling dies. The female incubates the eggs for 45 to 53 days, while the male provides food during this period.

While there are no specific reports of martial eagles abandoning their eggs due to human disturbance, other large eagle species, such as the wedge-tailed eagle, are known to exhibit this behavior. The wedge-tailed eagle is highly sensitive to human disturbance, and nest abandonment may occur if humans approach the nest, leading to the abandonment of the young.
In the case of martial eagles, the birds are known to be highly territorial and may aggressively defend their nests from perceived threats. If the nest is approached by humans, the female tends to sit tight, but the male may fly off. If the pair is disturbed repeatedly, they may eventually abandon the nest.
Martial Eagles and Meerkat Predation
Martial eagles are one of the most dangerous and frequent predators for meerkats, particularly for meerkat pups, which are most susceptible to predation during their first three months. Meerkats actively deter some of their predators, such as jackals and cape cobras, by mobbing as a group, but they tend to avoid larger predators, such as lions, spotted hyenas, and black-backed jackals.
Factors Affecting Nest Abandonment in Martial Eagles
While there are no specific reports of martial eagles abandoning their eggs due to human disturbance, there are several factors that can contribute to nest abandonment in these birds:
- Repeated Disturbance: If the nest is approached by humans repeatedly, the pair may eventually abandon the nest to avoid further disruption.
- Predation Threats: Martial eagles are known to be highly territorial and may abandon their nest if they perceive a significant threat to their eggs or hatchlings.
- Environmental Conditions: Extreme weather conditions, such as heavy rain or drought, can also lead to nest abandonment if the birds are unable to adequately provide for their young.
Conclusion
In summary, while there are no specific reports of martial eagles abandoning their eggs due to human disturbance, other large eagle species, such as the wedge-tailed eagle, are known to exhibit this behavior. Martial eagles are highly territorial and may aggressively defend their nests from perceived threats, but repeated disturbance, predation threats, and environmental conditions can all contribute to nest abandonment in these birds. Understanding the nesting behavior and ecology of martial eagles is crucial for their conservation and protection.
