Least Auklet Aethia pusilla
This tiny bird is probably the most abundant species of auk, a family that also includes murres and puffins. Short, plump, and gray-backed, with a stubby red-tipped bill, it nests in vast colonies off the Alaskan coast, some of which contain more than a million birds. Least auklets also feed together, floating on the surface in large gatherings known as “rafts.” They are pursuit divers that eat mainly zooplankton.
