The
Brandt's Cormorant is one of three cormorant species commonly found on the
west coast of the United States. They are found from southern Alaska
to northern Mexico, nearly always on salt water near the coast. Their
dark overall coloration is similar to the other two species found on the
west coast (Double-crested
Cormorant, Pelagic Cormorant). However, they can be readily
distinguished from these species by the lighter colored "chin" patch, and a
bright blue gular patch on the lower jaw when breeding.
Habitat: Breeds on islands and high slope areas
and the tops of cliffs on the mainland. Non-breeding birds often stay
close to breeding colonies at all times of the year, but may also sometimes
be found foraging well out at sea.
Diet: Feeds mostly on fish, but will also
sometimes each crustaceans, shrimp, squid, and other marine creatures.
Behavior: Strong swimmers and divers, they forage
by swimming on the surface and diving up to 150 feet below the surface in
pursuit of fish.
Nesting: Breeds in colonies, sometimes mixed with
other seabirds. The nest is built of seaweed and the bird's own
droppings, and is placed directly on the ground. Between 3 and 6 eggs
are laid, and both parents will help to incubate them. Upon hatching,
both parents help to feed the young, using regurgitation of caught fish.
Song: Usually silent away from their breeding
grounds. They do make very quiet grunting and croaking sounds at the
nest.
Migration: Considered a permanent resident
throughout much of their range. However, some non-breeding birds do
disperse outside of typical breeding areas, particularly southward along the
Mexican coast.
Similar Species:
In range, most likely to be confused with the Pelagic Cormorant or
Double-crested Cormorant.
