crested and pelagic cormorants
Alaska to Baja California
Pelagic cormorants live along open, windswept coasts. They nest along with other cormorants and other seabirds on steep, remote cliffs where they're safer from predators.
Unlike Brandt's cormorants, which sometimes hunt cooperatively, pelagic cormorants hunt alone, often diving into heavy surf for crabs, worms and small fishes. Though they often dive in shallow water along the shores, they also can make very deep dives—sometimes to 180 feet (55 m) or more.
Cormorants feed largely on fish of little commercial value, though in times past they were harassed by fishermen who blamed the birds for depleting their catches.
Safe nesting sites are becoming scarcer for cormorants and other seabirds.
Pelagic cormorants will use one nest for several years, piling up seaweed, grass and ocean debris until the mound is five to six feet high.
