Seems to be a small irruption this winter in Scotland. More than normal sightings.
One seen in December in upper glen in Angus (East coast) Most unusual, but beautiful.
Whilst visiting Shetland some 15 or so years ago, I had ultra close up of one which had landed on a fishing boat in the North Sea, and was handed over to the local santuary to recover after its ordeal. My best birding memory.
