Laysan Albatross
Phoebastria immutabilis

“I have a very large gull for you,” the animal control officer jokingly informed me when I greeted her at the door of San Pedro’s International Bird Rescue and Research Center.  She swung open the cage cover to reveal the most stunning creature I had ever seen.  Over a powerful beak surrounded by smooth, white feathers seemingly airbrushed with delicate shades of gray, I was staring into the large and disarmingly fearless eyes of a Laysan albatross.

Gliding effortlessly on wings adapted to lock open into a wingspan of nearly seven feet, the Laysan albatross frequents deep water off our California coast in search of squid, fish, fish eggs and crustaceans.  A 6,000-mile flight across open ocean is no extraordinary feat for a Laysan albatross, it’s simply a mundane errand for groceries.

Ranging widely across the North Pacific, albatrosses hunt primarily at night.  During the nesting season, prey are rendered into an oily baby formula delivered to nesting colonies off of Mexico, Japan and in the northern Hawaiian Islands.  Navigating vast expanses of the Pacific Ocean, the female albatross relies on the precision of her “bird brain” to guide her back to the small island where her lifelong partner waits, babysitting their hungry chick.  She may have been making this flawless journey for nearly half a century, raising one new chick at least every other year since she was eight.

Unfortunately, over this time new perils have invaded her blue realm.  Albatrosses drown as bycatch in commercial fisheries, are exposed to pollutants that have bioaccumulated in their prey, and fill their stomachs with plastic debris mistaken for food.  Over 300 plastic items have been found inside a single dead albatross chick.  These meals of plastic toys, lighters and bottle tops are fed to chicks by well-intentioned parents who, like many of us, have a difficult time discerning junk from food.  All of these dangers and distractions add to the challenge of racing across vast expanses of the Pacific Ocean to procure meals for a hungry chick.

The albatross I met seemed in no such hurry.  Somewhere at sea it had alighted upon a container ship that subsequently docked in the Port of Long Beach.  Fortunately, after careful examination, we found nothing wrong with our patient and released it back to its ocean home where, hopefully, it will still be gliding on locked wings when I retire.
