Curious about cormorants? So is Rover!

Today’s feathered feature is the Brandt’s cormorant Jody and I met on our last trip to sunny Southern California.
The Brandt’s cormorant (Phalacrocorax penicillatus) is a sea bird common to the Pacific Coast of North America, from California to Washington. The full range, however, is from southern Alaska to Baja Mexico, wherever the food is most plentiful. This sea bird depends heavily on the California Current, which moves south along the Pacific Coast of North America, causing upwellings of nutrients that attract the bird’s food. Its diet consists mainly of fish, along with shrimp and crabs. The Brandt’s cormorant is a great diver that descends from the water’s surface and uses its powerful webbed feet to swim masterfully. This cormorant commonly dives to depths of 40 feet, chasing prey that they grab with their hooked bill and then swallow whole.
We came across this juvenile Brandt’s cormorant on La Jolla’s beautiful coast.
Brandt’s cormorants have distinctive white cheeks, making them easy to identify. According to the Channel Islands National Park, California, “Brandt’s cormorants weigh about 4.6 pounds and measure 34 inches in length, with a wingspan of about 4 feet. Sexes look similar; with short black legs, a long black body and neck, and a dark bill with a hooked tip. Breeding adults have brilliant turquoise eyes and a bright blue gular pouch-distinctive among this species of cormorant-which fades quickly after the nesting season. Their breeding plumage also includes white plumes on either side of the head, neck, and back. Like other cormorants, Brandt’s cormorants often spread their wings out to dry after a dive, as their feathers are not completely waterproof and become soaked. This helps reduce buoyancy and allows the cormorant to forage deep under water.”
Juvenile Brandt’s cormorants (like the one we met) are brownish black with a lighter tan underside that forms a V-shape where the neck meets the chest.
The picture below shows the result of a pet owner disregarding San Diego County beach dog laws and commonly accepted beach pet etiquette. Although the bird seemingly remained calm, cool and collected, this unexpected encounter gave Jody and me a good scare! Luckily, Rover was just curious. He didn’t get any closer to the young cormorant before his errant owner realized where he was and called him off.
The inquisitive pooch was not only off-leash but was also on the beach within restricted hours. San Diego County has a very specific set of hours in which dogs are allowed on beaches, and at all times they must be kept on a leash.
Of course, our pal Rover didn’t know any better, but his human might want to consider planning a visit to one of the four special “Dog Beaches” on the San Diego Coast. They include Dog Beach-Ocean Beach, Fiesta Island-Mission Bay, North Beach Dog Run-Coronado, and Del Mar Dog Beach-Del Mar. Each of these beaches has their own rules. Stop by the county’s Dog Beaches site for details.
