Pigeon guillemot

Cepphus columba

The pigeon guillemot is a species of bird in the auk family, Alcidae. This seabird is found on North Pacific coastal waters, from Siberia through California to Alaska. The pigeon guillemot breeds and sometimes roosts on rocky shores, cliffs, and islands close to shallow water. In the winter, some birds move slightly south in the northern-most part of their range in response to advancing ice and migrate slightly north in the southern part of their range, generally preferring more sheltered areas.
