[edit] Description

This genus contains large owls of which many can raise feather tufts commonly called "horns". The members often carry the common name of Eagle-Owl, but when Ketupa is included some have names like Fish-Owl.

[edit] Taxonomy

Bubo is a genus in the family Strigidae.

[edit] Bubo vs. Ketupa

Some authorities (Howard & Moore, 2003; IOC 1.6, 2008) place Blakiston's Fish-Owl (blakistoni) in the genus Bubo. However, Clements 6th edition (2007) and Sibley & Monroe (1996) place this species in Ketupa, and the Opus awaits further clarification.

[edit] Bubo vs. Nyctea

Recently updated authorities (Clements 6th edition, 2007; IOC 1.6, 2008) have reassigned Snowy Owl (scandiacus/a) to the genus Bubo because DNA results place Snowy Owl among branches containing Bubo owls. However, Howard & Moore (2003) and Sibley & Monroe (1996) retain this species in Nyctea, and the Opus awaits further clarification.
