The last decent view I had of a snow bunting was this female three years ago, at the same place.
This BTO BirdTrack graph shows that snow bunting numbers have been low this winter.
Snow buntings are winter visitors found on north-east coasts or on high ground, mainly in Scotland. There is a tiny breeding population in the Scottish Highlands.
This is where they breed in Europe.
Snow buntings have circumpolar distribution and are common in North America, breeding in the Arctic and wintering either side of the US-Canadian border.
Thomas Bewick made this engraving for A History of British Birds (1797).
Snow buntings were obviously much more common in Bewick's time (as was snow).
As usual, he commented on their culinary attributes.
Archibald Thorburn painted a male snow bunting with a reed bunting, both in breeding plumage.
John James Audubon painted this plate for Birds of America.
