Least Auklet
Aethia pusilla
An abundant tiny auklet, only slightly larger than a sparrow. Occurs in large colonies around rocky shores during summer, and in smaller flocks further from the coast during winter. Summer plumage appears messy with numerous gray spots around the belly. Winter plumage is more contrastingly marked with flashing white belly and shoulders. Gives frequent, consistent squawks and squeaks at colonies. Readily separable from other auklets due to its whiter plumage and smaller size.

保护状况
Least auklets are vulnerable to oil spills and introduced species. The introduction of Arctic foxes to many of the Aleutian Islands caused the species to be wiped out on many of those islands, and rats are also a problem on many islands. However, at present they are still a very common species, and are not considered threatened by the IUCN.
