The Verreaux Eagle Owl (Bubo lacteus) is the largest owl in Africa and is also known as the Milky Eagle Owl or Giant Eagle Owl. The name commemorates the French naturalist Jules Verreaux. This owl is the world's fourth heaviest living owl, after Blakiston's fish owl, the Eurasian eagle-owl and the tawny fish owl, and is also the fourth longest living owl, after the great gray, Blakiston's fish and Eurasian eagle-owls.Verreaux's Eagle Owls live in monogamous pairs that defend their territory with calls and song, which can carry up to 5km. During courtship the birds perch near each other, producing fast stuttering hoots, bobbing up and down and flicking open the wings slightly. It is found in Africa south of the Sahara, south to the Cape.
