American horned owls (North and South America) and Old World eagle owls form the genus Bubo, as usual. The name of the genus Bubo is Latin for the Eurasian eagle.
This genus, depending on the definition, contains about one or two dozen distinctive owl species (the Strigidae family) and is found in many parts of the world. Some of the greatest living strigiformes exist in Bubo. Traditionally, only owls with ear crests are included in this genus, but that is no longer the case.
Data sequence of cytochrome b mitochondrial DNA (mtDNA) supports the decision to consider the snowy owl owls adapted to arctic conditions and transfer them to Bubo, so the Nyctea monotypic genus is not applicable.
The four owls previously in the genus Ketupa also moved to Bubo. However, the cytochrome myDNA data b shows in this case, make the Bubo monophyletic owl of Scotopelia owl also need to be included there. On the other hand, the genus then becomes quite large and unclear, and Bubo in the growing sense of two different clades. Thus birds and owls can be an alternative in Ketupa if there is a deviant eagle owl – good-bye sleeping ghost eagle ghosts, puffing, and eagle Usambara, possibly also the Fraser eagle owl and possibly the others – also moved to the genus. . Because some mysterious eagle owls remain on excluded and others – eg. Verreaux’s eagle – is an unfinished relationship, more research is needed.
