I'm working through my Puffins and of course that also includes auks and auklets... in the background, apart from the whiskered auklets, there are some crested and parakeet auklets swimming/flying around. The Whiskered Auklets breeds on Alaska's Aleutian Islands, where it is thought to nest on no more than 10 islands and Asia's Commander Island and south to Kurile Island. Its name is derived from the long white feathers on its face that are part of its breeding plumage. The whiskers have been shown to help them sense their way to and out of their nests at night. Neither the male nor the female builds a nest. Instead, the female lays one egg on bare rock or in a small crevice on a cliff face. A colonial breeder, Whiskered Auklet colonies often number far less than those of Least and Crested Auklets. Both parents feed young regurgitated food (marine zooplankton) at night. One of the smallest and rarest of the alcids in the U.S. (only the Kittlitz's, Craveri's, and Xantus Murrelets have smaller populations), the Whiskered Auklet breeds and winters largely in the remote Aleutian Islands of Alaska
