Synonyms: Strix lactea

Wikipedia Abstract

Verreaux's eagle-owl, also commonly known as the milky eagle owl or giant eagle owl, (Bubo lacteus) is a member of the family Strigidae. This species is widespread in sub-Saharan Africa. A member of the Bubo genus, it is the largest African owl measuring up to 66 cm (26 in) in total length. This eagle-owl is a resident primarily of dry, wooded savanna. Verreaux's eagle-owl is mainly grey in color and is at once distinguished from other large owls by its bright pink eyelids, a feature shared with no other owl species in the world. Verreaux's eagle-owl is a highly opportunistic predator equipped with powerful talons. Just over half of its known diet is comprised by mammals but equal or even greater numbers of birds and even insects may be hunted locally, along with any other appropriately si
