The scientific name for the Snowy Owl was recently changed from Nyctea scandiaca to Bubo scandiacus (Sangster et al. 2004). This decision was based upon both anatomical and behavioural traits which emphasized the species close relationship to eagle owls, in particular to Great Horned Owl Bubo virginianus. In the new monograph on the Snowy Owl (Potapov & Sale) the authors rejected such arguments and used the former scientific name of Nyctea scandiaca. They argue that the Snowy Owl is clearly distinct from Bubo-species both genetically and anatomically. They also mean that the Snowy Owl has arisen as a species in the Palearctic, and that it occupied its current distribution range round 4000 years ago.
