Guillemot "motion blur" image, made by panning with an intentional slow shutter speed. These birds are very fast flyers with extremely rapid wingbeats.
Closeup of Brunnich's Guillemots on their nests. Each bird lays a single pear-shaped egg. The oblong shape prevents the egg from rolling off the edge of the cliff.
