One reported this morning at Porth Dinllaen, Morfa Nefyn. Possibly the Penychain bird from a few days ago? Anyway, a good find for whoever it was - Roseates are very scarce down this way and always a delight to see.
Unfortunately, I was out of the area when Eddie relocated it at lunchtime as well as a Black Guillemot. A dash back early evening and in a flying visit I failed to connect with it from the beach by The Cliffs Hotel. There were a few very distant terns roosting on the rocks towards Nefyn but I couldn't hang around to explore any further.
