Pelagic Cormorant

Phalacrocorax pelagicus
Pelecaniformes
These birds are aquatic, medium-sized to large, and feed on small fish and other animals found in the water. One of their most distinctive features is their feet, which have webbing between all four toes. Many have an unfeathered and sometimes brightly colored pouch of varying size at the throat. Most nest in colonies. Representatives of five of the order's six families have been found in Washington:
Phalacrocoracidae
Cormorants are large birds with long, flexible necks, short, rounded wings, and wedge-shaped tails. Most are predominantly shiny black, and males and females look alike. Diving to catch fish, they swim underwater and use their feet but not their wings to propel themselves. Their feathers get waterlogged quickly, which aids them in diving by reducing their buoyancy. As a result, they need to dry out between dives, and many species are often seen perched with wings spread. Distributed throughout temperate and tropical waters, cormorants most often live along marine coastlines, but a few species live on inland waters as well. They are colony nesters, nesting on banks, cliffs, or trees, often on islands. Both parents raise the young.

General Description

The smallest cormorant in Washington, the Pelagic Cormorant is slender, with an especially slender neck and beak. Both males and females are solid black, except during the breeding season when adults have white rump patches that show in flight.

Habitat

Exclusively marine, Pelagic Cormorants can be found in bays and sounds and on the coast (although usually fairly close to shore). They breed on small, offshore islands and rocky cliffs with deep water at the base.

Behavior

They are generally less social than other species of cormorant. Feeding is a solitary activity. Pelagic Cormorants, like other cormorants, catch most of their prey underwater. Nesting colonies are in hard-to-reach places, as cormorants are more successful at excluding predators than in actively defending against them.

Diet

Small fish make up most of the diet, with crustaceans and other marine animals making up a small portion as well. Much of the foraging is close to rocks.

Nesting

Pelagic Cormorants nest in colonies, which are smaller than those of other cormorants. Colonies are situated on islands, narrow cliff ledges, steep slopes, and other relatively inaccessible locations. The male displays at a nest site by flashing his white patches. Together the male and female construct a nest of seaweed, grass, moss, and occasionally sticks. This nest may be reused from year to year. The female lays a clutch of 3-4 eggs. Both parents incubate and feed the young.

Migration Status

Birds that breed in Washington are permanent residents here, but birds breeding farther north may winter in northern Washington waters.

Conservation Status

Cormorants as a group have been killed and harassed by people who believe that the birds damage the commercial fishing industry. (Pelagic Cormorants, however, feed on fish that aren't fished by commercial fisheries.) Oil spills, gill-net entanglement, and toxic contamination of prey also affect the population. In Washington, significant increases in the population were recorded between 1976 and 1992.

When and Where to Find in Washington

Numerous in northern Puget Sound, Pelagic Cormorants nest on a number of islands throughout the sound. Historically, large colonies have been found on Protection Island in Jefferson County, Smith/Minor Island in Island County, and Jagged Island in Clallam County.
