The least auklet is a small seabird belonging to the family Alcidae, which includes other birds like the puffin and razorbill. It measures about 6 to 7 inches in length and weighs around 4 ounces. These birds are primarily found in the northern Pacific Ocean, particularly in areas like the Bering Sea and along the coasts of Alaska and Russia. They are known for their distinctive black and white plumage and small size. Least auklets are social birds that often nest in large colonies on rocky cliffs and islands. They feed mainly on small marine invertebrates, such as krill and copepods, which they catch while diving underwater. During the breeding season, they lay one egg in a burrow or crevice, and both parents share the responsibility of incubating the egg and feeding the chick once it hatches.
