Cassin’s auklet (Ptychoramphus aleuticus) is a small, chunky seabird that ranges widely in the North Pacific. It nests in small burrows and because of its presence on well studied islands in British Columbia and off California it is one of the better known auks. It is named for John Cassin, a Pennsylvania businessman and naturalist.
