A possible wilson's snipe was a Eiði, Faroe Islands from 25th of october to at least 30th. I saw it a few times, but did not get pics of the underwing or tail. You can see the bird here:
When flushed it called quite different from our common snipes. The call was more hoarse and dry and sort of less melodious than our local birds, which have a much clearer tone when calling. It's hard to describe a call in letters, but the difference was easy to hear.
