The pigeon guillemot is a small seabird native to the northern Pacific Ocean. Guillemots, like puffins and murres, belong to a group of seabirds known as auks, or alcids. Guillemots and other alcids are well adapted for life on the ocean. They have short, strong wings and legs set far back on the body, making them excellent swimmers and divers.
