Many seabirds, including California brown pelicans, loons and grebes, starved to death in recent months as record-setting ocean temperatures decreased the band of cold, nutrient-rich surface water<\/a> where krill, anchovies and sardines thrive near the shore, said Russell, a postdoctoral scholar at the University of California, San Diego, Scripps Institution of Oceanography.<\/p>\n \u201cWe\u2019ve been seeing cormorants walk to shore and then just die within the hour. I mean one time it happened within 15 minutes, and I\u2019ve never seen that before,\u201d Russell said. \u201cThat has been heartbreaking for me and we\u2019re seeing this happening across the whole coast.\u201d<\/p>\n Scientists fear the die-off could worsen with the recently formed El Nino, the natural warming of parts of the central Pacific that alters weather worldwide and spikes global temperatures.<\/p>\n Die-offs of seabirds is happening more with warming oceans<\/p>\n <\/p>\n Beachgoers pass a dead common murre on a beach near Scripps Pier during a survey for dying seabirds Wednesday, May 6, 2026, in San Diego.

This year, saw three stations break records for 40 days or more, said the director Melissa Carter, who runs the program. The samples are taken in a variety of ways, including off piers by dropping an insulated bucket, or by lifeguards in the early morning surf or researchers off rocky shorelines.<\/p>\n Robotic underwater gliders with sensors operating out at sea also recorded high temperatures offshore and at depth during the spring. Dan Rudnick, who runs the Scripps glider program, said the warm temperature anomaly off Southern California this spring was comparable to that during the last El Nino in 2023. <\/p>\n <\/p>\n A common murre spreads its wings in a rehabilitation tank at the SeaWorld Animal Rescue Center on Thursday, May 14, 2026, in San Diego.

A similar pattern happened a decade ago. <\/p>\n \u201cWe don\u2019t know how bad this is going to get,\u201d said Russell, who has written about five species of Booby that are now common off California<\/a> because of warming ocean temperatures.<\/p>\n Seabirds are seeking food in unusual places<\/p>\n <\/p>\n A common murre lies on a beach near Scripps Pier during a survey for dying seabirds Wednesday, May 6, 2026, in San Diego.

Bergeron, the CEO of \u2060International Bird Rescue<\/a>, a global wildlife conservation organization that runs two aquatic bird rehabilitation centers in California, said in an interview in May. <\/p>\n Brown pelicans are turning up in inland lakes, Bergeron said.<\/p>\n \u201cWhen birds starve, especially the pelicans, they start to look in unusual places for food,\u201d he said. \u201cThey will chase fishing boats, they will go to piers and you end up with birds with fishing line and fish hook injuries.\u201d<\/p>\n Many dead or debilitated seabirds examined this year have been young and emaciated, and most have tested negative for avian flu, according to the California Department of Fish and Wildlife. Some had opportunistic infections linked to malnourishment.<\/p>\n Krysta Rogers, a senior state environmental scientist, said there may be factors besides warm ocean temperatures. High mortality rates among young Brandt\u2019s cormorants and common murres began after a robust 2025 breeding season, peaking post-winter, and appeared to coincide with the marine heat wave. Those deaths may be mostly due to chicks simply not surviving on their own, she said.<\/p>\n But she does not discount the marine heat wave affecting some seabirds, considering an increase this spring in reported deaths from other species and not just young ones.<\/p>\n The U.S. Fish and Wildlife Service, which collects data from the dead seabird surveys and others, said they do not have a comprehensive report ready yet.<\/p>\n Only a fraction of birds that die at sea wash ashore<\/p>\n <\/p>\n Marine ornithologist Tammy Russell, right, and Alex Rubenstein search for dead seabirds under Scripps Pier during a survey Wednesday, May 6, 2026, in San Diego.

One of the strongest El Ninos on record overlapped with it in 2015.<\/p>\n Carcasses of emaciated common murres showed up on beaches in what biologists say was the largest seabird die-off recorded in the world\u2019s oceans.<\/p>\n Common murres look like thin penguins. They can fly miles in search of schools of finger-length fish and can dive and swim nearly 600 feet (183 meters) deep to capture them. However, the birds\u2019 high metabolism means they have to eat a lot. If they don\u2019t eat prey matching 10% to 30% of their body mass daily, they can use up fat reserves and drop to a critical threshold for starvation within three days.<\/p>\n Studies show that only a fraction of birds that die at sea wash ashore. It took years for scientists to confirm that more than half of Alaska\u2019s population of common murres, an estimated 4 million birds, died during \u201cthe blob,\u201d according to a 2024 study in the journal Science.<\/p>\n The species is still struggling to recover.<\/p>\n ___<\/p>\n The Associated Press\u2019 climate and environmental coverage receives financial support from multiple private foundations.
