Snow bunting

Wikipedia

The snow bunting is a passerine bird in the family Calcariidae. It is an Arctic specialist, with a circumpolar Arctic breeding range throughout the northern hemisphere. There are small isolated populations on a few high mountain tops south of the Arctic region, including the Cairngorms in central Scotland and the Saint Elias Mountains on the southern Alaska-Yukon border, as well as the Cape Breton Highlands. The snow bunting is the most northerly recorded passerine in the world.

Useful to know

An Arctic specialist, the snow bunting breeds farther north than any other passerine. Males often arrive on breeding grounds weeks before snow melts and sing from exposed rocks. They have feathered tarsi that help insulate against extreme cold. Small alpine populations persist far south of the Arctic in places like Scotland’s Cairngorms and Alaska–Yukon’s Saint Elias Mountains.
