Status assessment and conservation priorities for a circumpolar raptor: the Snowy Owl <i>Bubo scandiacus</i> Open
Summary The global population and status of Snowy Owls Bubo scandiacus are particularly challenging to assess because individuals are irruptive and nomadic, and the breeding range is restricted to the remote circumpolar Arctic tundra. The …
