Black eagles, also known as Verreaux’s eagles, are large birds of prey found in southern Asia and Australasia. They are known for their impressive size and strength, with the ability to carry significant weights. In this blog post, we will explore the specifics of how heavy a black eagle can carry.
The Lifting Power of Black Eagles
Black eagles are one of the largest eagles in their range, with a wingspan of up to 6 feet and a weight of up to 3.5 pounds. This impressive size and strength translate to a significant lifting power. According to experts, the best estimates put the lifting power of a black eagle at around 4-5 pounds.
However, it’s important to note that this lifting power is dependent on the eagle’s airspeed. The faster the bird is flying, the greater its lift potential. This means that a black eagle may be able to carry heavier loads when it is in flight compared to when it is perched or taking off.

Given their lifting power, black eagles are capable of carrying a variety of prey items, including:
- Small to medium-sized mammals, such as squirrels, mice, and rats
- Birds, including smaller birds and bird eggs
- Bats
- Monkeys
In fact, there have been documented cases of black eagles carrying away entire bird’s nests in order to get at the chicks and/or eggs inside. This demonstrates the impressive strength and hunting prowess of these birds.
Factors Affecting Carrying Capacity
While black eagles have significant lifting power, there are several factors that can affect their carrying capacity:
-
Airspeed: As mentioned earlier, the faster the eagle is flying, the greater its lift potential. This means that a black eagle may be able to carry heavier loads when it is in flight compared to when it is perched or taking off.
-
Wind Conditions: Strong winds can provide additional lift, allowing the eagle to carry heavier loads. Conversely, calm or adverse wind conditions may limit the eagle’s carrying capacity.
-
Body Condition: The overall health and physical condition of the eagle can also impact its carrying capacity. An eagle that is well-fed and in good physical condition will have a greater lifting power compared to one that is injured or malnourished.
-
Prey Size and Weight: The size and weight of the prey item can also influence the eagle’s carrying capacity. Larger or heavier prey may be more challenging for the eagle to lift and transport.
Hunting Strategies and Prey Handling
Black eagles are skilled hunters and have developed various strategies to capture and transport their prey. They often use their powerful talons to grasp and lift their prey, and may even use their beaks to help secure the prey during transport.
In some cases, black eagles have been observed working in pairs to capture and carry larger prey items. One eagle may distract or flush the prey, while the other eagle swoops in to capture it.
Conclusion
In conclusion, black eagles are impressive birds of prey with a significant lifting power, estimated to be around 4-5 pounds. They are capable of carrying a variety of small to medium-sized prey items, including small mammals, birds, and even entire bird’s nests. However, their carrying capacity is influenced by factors such as airspeed, wind conditions, body condition, and prey size and weight. Understanding the capabilities and hunting strategies of black eagles can provide valuable insights into the ecology and conservation of these remarkable birds.
