genus of birds
(Redirected from Eagle owl)

Bubo is a genus of large owls. It includes the eagle-owls (Old World) and the horned owls (the Americas). This genus contains about one or two dozen species of typical owls (family Strigidae) and is found in many parts of the world. Some of the largest living Strigiformes are in Bubo. Traditionally, only owls with ear-tufts were included here, but that is no longer the case.

Scientific classification

Mitochondrial DNA (mtDNA) cytochrome b sequence data supports the decision to put the snowy owl, an eagle-owl adapted to Arctic conditions, into Bubo.[3]

The fish-owls in the genus Ketupa, and the Scotopelia fishing owls, are also closely related. They might be moved into Bubus, but that would make the genus rather large. As it is some of these owls, like Verreaux's eagle-owl, are not studied enough. More research is needed.[3]
