Some authors have wondered whether the Blakiston's represents an intermediate step between traditional eagle-owls and the other fish owls, despite the current gap in distribution between Blakiston's and other fish owls. Given that it shares genetic material and osteological characteristics with the Eurasian eagle-owl, yet also seems to share some characteristics with the other three fish owls (especially the brown fish owl), the place of the Blakiston's fish owls in this evolutionary chain is ambiguous. However, the other fish owls are not believed by some authors to be divergent enough to support a separate genus either and so some authorities list fish owls as also included in the genus Bubo. This was proven by osteological and DNA-based tests in 2003 by ornithologists/taxonomists Michael Wink and Claus König, author of Owls of the World. dumeril), than to the subgenus of fish owls it was formerly believed to be closer to, i.e. This is because it is more closely related to the Eurasian eagle-owl (by studies of the main subgenus of the species, B. It is more correct to call this species the Blakiston's eagle-owl.
