Justification of Red List category
This iconic large owl of Arctic regions is listed as Vulnerable as it is undergoing rapid population declines in North America and probably also in northern Europe and Russia. Drivers of the decline are uncertain but likely include climate change affecting prey availability, as well as collisions with vehicles and infrastructure. There remains some uncertainty about the overall rate of decline, and if it proves to be even higher the species may be eligible for further uplisting to Endangered.
