There's a few birds in that part of Scotland, I know because my mate works for the RSPB there counting Guillemots.
Shetland is actually a set of sub-arctic islands and they are closer to Norway than to the Scottish capital Edinburgh.
Good luck.
Was there last year, very laid back place and the type of place that you stop everywhere where you can.
Obviously there’s the seabirds, but worth going to see is the gin distillery.
