One of the marks of a Common Murre is a downcurved stripe-like mark from the eye back across the cheek. When I saw this bird at first I thought it was a Murre because of the face pattern. The photo,however, shows the thick blunt bill of a Razorbill. I checked a variety of books to see if a Razorbill exhibits this pattern and none of the US books showed it as strong as this, but page 211 of Birds of Europe (second edition)by Svensson, Mullarney and Zetterstrom (Princeton university Press) shows the two 1st winter plumages and assures me (along with the big bill) that this is a 1st winter Razorbill.
This is one of at least a dozen Razorbills that were unusually close to the Gurnet point today. There were at least 20 additional large alcids further offshore that I could not confidently identify as they showed a variety of plumage patterns. Almost certainly they were Razorbills but a murre could easily have been among them.
