Great Horned Owl
The American horned owls and the Old World eagle-owls make up the genus Bubo, at least as traditionally circumscribed. This genus, depending on definition, contains about one or two dozen species of typical owls (family Strigidae) and occurs 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 this is now known to be wrong.
