Struggled through the snow and ice to Stromness for an afternoon and lunch out. Eventually the Iceland Gull put in a fleeting appearance, appearing from nowhere it flew a few feet over my head and then disappeared behind the ferry terminal. I had been hoping to get a good enough view to age this bird properly as there seems to be some disagreement about its years, or maybe there are two? Unfortunately the view was inconclusive except to say it's not an adult.
A few other bits and bods around the harbour including a Pied Wagtail, I haven't seen one of those for a while. A grebe on the far side defied ID (no scope).
