With reference to Sash's post below, we had a phone call from the folks at Slate Mill yesterday to come and rescue an "injured guillemot" in their garden. It was of course a Manx Shearwater under a bush, which had arrived overnight in the fog and was possibly attracted to their outside light. (The same thing happened to us in April 2020 when a Shearwater was attracted to my moth light see Lost Shearwater.). Anyway, this shearwater appeared fit and well so Peter released it at Rennie Slip yesterday evening - it flew competently away towards the islands.
