Aerial clouds of birds are composed of Common Murres, Atlantic Puffins, Black Guillemots, Black-legged Kittiwakes and Razorbills. The worlds's second largest colony of Leach's Storm-petrel also nest here but we didn't see them on this visit.
Competent photography is difficult due to the lack of depth of field of telephoto lenses. Wider angle lenses would capture more in focus birds but alas the images would look like a spray of gnats.
If you study the images you might pick out birds other than the Common Murre. Good luck!
This photo has at least one Atlantic Puffin.
