I just ran Merlin on the photo, and it came up with Pigeon Guillemot as first choice, and Common Murre as second choice. The app doesn’t provide details about the level of confidence in first choice vs second choice, so I can’t tell whether it considered it a close call or not. But usually, if it has a high-confidence ID, it will only list a single choice, so the fact that it listed two possibilities gives some indication of it not being a very high confidence ID.
