Breeding Behavior and Life Cycle of the Madagascar Serpent Eagle
The Madagascar serpent eagle’s breeding season typically begins in late September and extends through early December. During this time, these birds engage in elaborate courtship displays to attract mates. Soaring high above the forest canopy, the males perform impressive aerial acrobatics, displaying their agility and vocalizing loudly.
Once pairs have formed, they select a suitable nesting site, often high up in a tree, at heights ranging from 15 to 30 meters. The nests are constructed from sturdy branches and lined with softer materials such as leaves and feathers.
The female eagle lays a single egg in the nest, which is incubated for approximately 45 days. Both parents share the incubation duties, taking turns to keep the egg warm and protected. Upon hatching, the chick is altricial, meaning it is entirely dependent on its parents for food and care.
For the next two to three months, the chick remains in the nest, rapidly growing and developing under its parents’ watchful eyes. Both parents actively hunt and bring prey back to the nest to feed their young. Once the chick is strong enough, it begins to venture outside the nest, testing its growing wings and exploring its surroundings.
Eventually, the young eagle becomes independent and leaves the nest to establish its own territory and find a mate. The lifespan of a Madagascar serpent eagle is estimated to be around 12 to 15 years in the wild.
