A boldly white-and-rufous Arctic sparrow whose winter flocks swirl across snow-covered fields like flying snowflakes.
§ Quick facts
§ Encyclopedia
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.
