The
Pelagic Cormorant is the smallest and lightest of the North American
cormorants. They breed from California all the way to the Aleutian
Islands and west coast of Alaska, and can usually be found in most of the
same range in winter, provided it is ice-free. They are very similar
to the Red-faced Cormorant, a species found just in the Alaska portion of
the Pelagic Cormorant's range.
Habitat: Breeds on offshore islands and rocky
cliffs. Outside of the nesting period, they are usually found
relatively close to the coastline, although occasionally they can be found
well out to sea.
Diet: Feeds mostly on fish, but will also feed on
other marine life, including crabs, marine worms, shrimp, and other small
creatures.
Behavior: Forages by swimming on the water's
surface and diving down to obtain prey, with dives going up to 100 feet or
more in depth.
Nesting: Breeds in colonies, but typically smaller
colonies than other West Coast cormorant species. The nest is built of
grasses, seaweed, and other vegetative material, cemented together with
their own waste. Females usually lay between 3 and 5 eggs, and both
parents help to incubate them. Upon hatching, both parents feed the
nestlings, through regurgitation of fish.
Song: Usually silent away from breeding sites.
At the nest site, makes a variety of quiet grunting and hissing sounds.
Migration: Pelagic Cormorants are found year-round
in most of their breeding range, but withdraw in winter from the
northernmost parts of their range along the
western coast of Alaska. Other birds also obviously move southward for the
winter, as birds are found in greater numbers in southern California and
Baja California in winter than during the breeding season.
Conservation Status: Populations are likely
decreasing, but they are still found across a wide geographic range and are
fairly common in some locations.
The
IUCN lists the Pelagic Cormorant as a species of "Least Concern".
