Scientists on a research vessel off central California said they spotted a waved albatross roughly 3,000 miles from where the species typically breeds, a distance that has left marine bird researchers searching for an explanation. The observation occurred about 23 miles off the coast of Point Piedras Blancas, roughly midway between San Francisco and Los Angeles.
The waved albatross is known as a “vagrant” when it travels far outside its typical range, and the researchers said the Central California sighting marked only the second recorded observation of the bird north of Central America. They also said the individual bird appeared to be the same one seen earlier off Northern California, with Tammy Russell noting that it did not look like it was turning back quickly.
Russell, a contract scientist with the Farallon Institute and a postdoctoral scholar at the University of California, San Diego’s Scripps Institution of Oceanography, said the bird’s arrival raised questions about how it ended up so far from its Galapagos breeding grounds. She said the bird “doesn’t seem to be in a hurry to get back south,” and described the scenario as unusual given that the species is known to spend much of its life over the ocean.
In a message on Facebook, Russell wrote, “I can’t even believe what I saw,” adding, “I’m still in shock.” She later said it is “all but impossible” to determine why the bird ventured so far north.
Russell said weather could have played a role, suggesting the bird may have been driven north by a storm. She also said the albatross could have been traveling as part of its seasonal cycle, noting that adults lay their eggs in spring and that chicks leave nests by January, which could leave the bird wandering during the remainder of the year before returning.
Russell added that the timing could matter if the bird did not breed last season, writing in an email that it might have been “wandering on [its] year off” and would soon return to the Galapagos to reunite with its mate for the next breeding season. She also said, “Who knows how long it will stay around or if it will ever return?” and described the uncertainty as part of what makes the sightings “so special.”
Other ornithologists cautioned against assuming that a single sighting necessarily signals a long-term movement of the population. Marshall Iliff, eBird project leader at Cornell University’s Lab of Ornithology, said seabirds such as albatrosses can travel great distances in search of food, and he noted that “The odd individual routinely may turn up far from home, even in the wrong hemisphere or exceptionally in the wrong ocean.”
Iliff said food shortages could prompt a bird to wander, but he stressed that “There is no evidence at this point that this is anything but a fluke.” The researchers said that framing reflects the limited information from the sighting itself and the need for additional observations.
Conservation groups describe the waved albatross as critically endangered. The International Union for Conservation of Nature classifies the bird as critically endangered, and the American Bird Conservancy says its range is restricted to the tropics; the birds nest on lava fields among scattered boulders and sparse vegetation. The researchers said the birds can live up to 45 years and feed primarily on fish, squid and crustaceans.
Russell said that if multiple waved albatrosses were turning up in California, it could point to environmental drivers pushing birds northward, and she referenced her prior work on five species of booby that have become more common off California as warming temperatures and marine heatwaves affect the region. For the lone albatross she described, Russell said the current record still provides a starting point: “If this is a sign of this species moving north, we now have some baseline data when we first detected one.”
