I photographed this lovely mystery bird a couple days ago in stunning Helsinki, Finland, can you ID the species and tell me how it got its peculiar English common name?
This goose was once thought to start life as Goose Barnacles growing on driftwood — perhaps because no one had ever seen it nesting (not surprising, since it breeds in the Arctic).
