The
Crested Auklet is identifiable by the shaggy crested of feathers that
protrudes from the forehead and dangles over the bill. They are found
in the far North Pacific, nesting on rocky islands in the Aleutian Island
chain and in the Bering Sea. They are a common sight in much of their
historical range, far outnumbering the somewhat similar
Whiskered Auklet. Crested
Auklets are known for their unusual citrus-scented plumage.
Habitat: Nests on rocky islands in the Aleutians
and Bering Sea, as well as near Siberia. When foraging and outside of
the breeding season, may be found well out to sea, or around upwelling
currents near the coast.
Diet: Feeds on small crustaceans such as copepods,
shrimp, and amphipods, as well as mollusks, fish, squid, and marine worms.
Behavior: Feeds by swimming underwater in search
of prey, with dives as deep as 100 feet. Gregarious, with tightly
formed flocks often seen flying around breeding colonies.
Nesting: The nest is a shallow scrape in the
ground, or a layer of pebbles in a crevice or hollow in the rocks. The
female lays a single egg, which is incubated by both parents. Both
parents help to feed the young when it hatches.
Song: On their breeding Colonies, Crested Auklets
have a variety of short calls, including a hoarse barking and a cooing call.
Migration: Considered a permanent resident in the
southern part of their range, such as around the Aleutian Islands where open
water exists all year. Populations nesting in the Bering Sea, where
ice forms in the winter, move southward for the winter, with most wintering
around the Aleutian Islands. They are only rarely found away from the
far north Pacific, with a stray once found as far south as British Columbia.
Birds that nest in Siberia winter in northern Japan.
Similar Species:
Most likely species to be confused with the Crested Auklet is the
Whiskered
Auklet.
Conservation Status:
Populations of Crested Auklet undoubtedly declined int eh 20th century, as
introduced rats and foxes on their breeding islands reduced breeding
success. However, despite population declines,
the IUCN currently lists the Crested Auklet as a species of "Least Concern".
They still are relatively common throughout their historical range.
