Cape Eagle-Owl (Bubo capensis) The Cape Eagle-Owl is a large, powerful predator capable of taking prey up to the size of a young Dassie or a Common Duiker lamb. It prefers mountainous habitat, and is never found far from rocky ridges. It roosts by day in the shade of a rock or a shrub, usually on the ground. It is very reluctant to fly in daytime, as it is mercilessly mobbed by raptors and crows. It will occasionally prey on other birds, even other owls. It is sometimes confused with the more common Spotted Eagle-Owl, but the latter has yellow, not orange eyes and much weaker claws.
