The Brown Snake Eagle (Circaetus cinereus) is a large bird of prey found in sub-Saharan Africa, known for its diet consisting almost entirely of snakes, including venomous ones. While the exact weight a Brown Snake Eagle can carry is not explicitly stated, it can be inferred that they can carry prey weighing up to approximately 2.8 kg (6.2 lb), based on their own weight range and the size of the snakes they typically hunt.
The Weight Range of a Brown Snake Eagle
According to the information provided, the Brown Snake Eagle has a wingspan of 164 cm and weighs between 1.5 to 2.5 kg (3.3 to 5.5 lb). This weight range gives us a good indication of the size and strength of these birds of prey.

The search results mention that Brown Snake Eagles can take snakes up to 2.8 meters long. This is a significant size, considering the weight and size of the eagle itself. While the snake’s body mass is not evenly distributed, it can be assumed that the eagle carries the snake by the head, which would account for a significant portion of the snake’s weight.
Handling Venomous Snakes
One of the unique adaptations of the Brown Snake Eagle is its ability to handle venomous snakes with minimal risk. These birds have thick-skinned legs that provide protection against snake bites, and they also have a unique method of crushing the head of any snake they catch to discharge the venom, minimizing the risk of being envenomated.
Factors Affecting the Weight a Brown Snake Eagle Can Carry
The weight a Brown Snake Eagle can carry may be influenced by several factors, including:
-
Size and Strength of the Individual Eagle: Larger and stronger eagles may be able to carry heavier prey than smaller or weaker individuals.
-
Prey Size and Weight Distribution: The size and weight distribution of the snake or other prey can affect the eagle’s ability to carry it effectively.
-
Environmental Conditions: Factors such as wind, terrain, and distance to the nest or feeding area may impact the eagle’s carrying capacity.
-
Nutritional Needs: The eagle’s nutritional requirements and the energy demands of carrying the prey may also play a role in the maximum weight it can transport.
Comparison to Other Eagle Species
While the Brown Snake Eagle is a large and powerful bird of prey, it is not the largest or strongest eagle species. For comparison, the Steller’s Sea Eagle, one of the largest eagles in the world, can carry prey weighing up to 9 kg (20 lb). However, the Brown Snake Eagle’s specialized diet and adaptations make it a formidable hunter in its own right.
Conclusion
In summary, the Brown Snake Eagle is a remarkable bird of prey that can carry prey weighing up to approximately 2.8 kg (6.2 lb), based on its own weight range and the size of the snakes it typically hunts. Its unique adaptations, such as thick-skinned legs and the ability to crush venomous snake heads, allow it to safely and effectively hunt and transport its prey. While not the largest eagle species, the Brown Snake Eagle is a highly specialized and impressive predator in its own right.
