It hunts by dropping to the ground from its perch in the understory, where it may strike its prey repeatedly with its feet; this serpent eagle may also grab prey from the foliage while hunting. Its large eyes enable this species to hunt in low light, though it is diurnal. Studies on the species' eyes have shown that they have about two times the visual resolution of a human's. It may breed from October to December in Gabon and from June to November in the Democratic Republic of the Congo.
