The African hawk eagle, also known as the crowned eagle, is a powerful bird of prey that is native to parts of tropical Africa. It is considered to be one of the most powerful raptors in Africa, and is known to prey on animals as large as bushbuck, which can weigh up to 30 kg (66 lb).
The Size and Strength of the African Hawk Eagle
In terms of size, the crowned eagle is a very large eagle, with females being around 10-15% larger than males. The average body mass of a crowned eagle is around 3.64 kg (8.0 lb), with some individuals weighing up to 4.7 kg (10.4 lb). The wingspan of a crowned eagle typically ranges from 1.51 to 1.81 m (4 ft 11 in to 5 ft 11 in), with the largest authenticated wingspan for a female being 1.9 m (6 ft 3 in).
The crowned eagle’s staple diet consists mostly of mammals, with a typical prey range of 1 to 5 kg (2.2 to 11.0 lb). However, the eagle is also known to attack and kill prey that is much larger than itself, with some reports suggesting that it can lift more than its own body weight in flight.

In one study, it was found that 91% of the bones collected from crowned eagles in the South African Museum were from juvenile specimens of large antelope species, indicating that the eagle is capable of taking down large prey.
Despite its power and size, the crowned eagle is not the heaviest eagle species in the world. That title goes to the harpy eagle, which is found in the rainforests of Central and South America and has an average prey weight range of 6.8 kg (15 lb). However, the crowned eagle is still a formidable predator and is considered to be one of the most powerful raptors in Africa.
Factors Affecting the Carrying Capacity of the African Hawk Eagle
The carrying capacity of the African hawk eagle can be influenced by several factors, including:
-
Body Size and Strength: The larger and more muscular the eagle, the more it can carry. Females are typically larger than males, giving them a greater carrying capacity.
-
Prey Size and Weight: The eagle’s carrying capacity is directly related to the size and weight of its prey. Larger prey, such as bushbuck, can be carried, but smaller prey is more commonly targeted.
-
Flight Conditions: The eagle’s carrying capacity can be affected by factors such as wind, altitude, and the distance it needs to fly. Stronger winds and higher altitudes can make it more difficult for the eagle to carry heavy prey.
-
Hunting Technique: The way the eagle hunts and captures its prey can also influence its carrying capacity. For example, if the eagle is able to surprise and subdue its prey quickly, it may be able to carry a heavier load.
Conclusion
In conclusion, the African hawk eagle is a powerful and impressive bird of prey that is capable of carrying and hunting prey much larger than itself. While it is not the heaviest eagle species in the world, it is still a formidable predator that is known for its strength and hunting prowess.
