African hawk eagles typically lay their eggs between April and August. They usually lay a clutch of 1 to 2 eggs, with the eggs being laid at 3 or 4 day intervals. The incubation period lasts for 42-44 days, during which the female does most of the incubation, being relieved for short periods by the male.

Egg Characteristics

The eggs of the African hawk eagle are chalky white with variable markings, and measure 59.5 to 75.2 mm in height and 46 to 55.7 mm in diameter. The weight of the eggs is reported to be 75 to 100 g, averaging some 87 g.

Chick Development

The chicks are covered in dark grey down when they hatch, with a whitish down on the abdomen and thighs, and a dull yellow cere and feet. The first coat of grey down gives way to a thicker and whiter second coat by 2 weeks.

Siblicide

The chicks practice siblicide, with the first-born chick often crushing, acquiring more food than, and inevitably killing the second, smaller chick. This is a common occurrence in many bird species and allows for a chick to thrive in the unlikely event that the first chick dies, there will be the second chick to propagate the species.

Breeding Habitat

African hawk eagles are found in a variety of habitats, including dense forests, woodlands, and savannas. They build their nests high up in the trees, often using the same nest site year after year.

Feeding Habits

These birds of prey are known to feed on a variety of small to medium-sized animals, including small mammals, birds, reptiles, and even some insects. They use their sharp talons and hooked beaks to capture and tear apart their prey.

Conservation Status

The African hawk eagle is classified as Least Concern on the IUCN Red List of Threatened Species. However, their populations are threatened by habitat loss, hunting, and persecution by humans.

Conclusion

The African hawk eagle is a fascinating bird of prey with a unique breeding strategy. By understanding when they lay their eggs and how their chicks develop, we can better appreciate the adaptations and behaviors that allow these birds to thrive in their natural habitats.
