Brown pelicans found weak on coast

Brown pelicans are turning up on Northern California beaches and in odd inland spots because they’re starving, not because they’re suddenly “tame” or sick with bird flu. Rescue teams in Fairfield and San Pedro have been taking in weak, emaciated birds for weeks, and the pattern now lines up with a much bigger ocean problem — a marine heat wave that has scrambled where pelicans can find food. ### Why are pelicans washing up now? The short version is food stress. Brown pelicans feed by plunge-diving for fish near the surface, but warmer water can push prey into different places or deeper water. When that happens, pelicans burn energy searching and come up short. By early May, International Bird Rescue’s Fairfield center was caring for about 20 starving pelicans, while its Southern California center had nearly 50 more. ### Is this just a Bay Area problem? No — it’s a California coast problem that’s showing up especially clearly in the Bay Area right now. International Bird Rescue says it has been responding to a statewide starvation event since March 2026, affecting brown pelicans, Brandt’s cormorants, and common murres. Its April 22 tally listed 161 admissions since March, including 57 Southern California brown pelicans and 8 in Northern California, with more cases still arriving after that update. ### So is the marine heat wave really the driver? That’s the leading explanation, and it fits both the bird behavior and the ocean data. NOAA’s California Current heat-wave tracker says large parts of the West Coast — especially central and southern California — were still being hit in mid-April by a large marine heat wave it has tracked since May 2025. These events are known to shift marine life, disrupt food webs, and echo some of the same ecological damage seen during the 2014–2016 Blob. ### Could this be bird flu instead? Mostly, no. California wildlife officials said on March 27 that starvation was the primary cause in the seabird die-off they examined. Testing found no avian influenza in the 33 Brandt’s cormorants checked by the state, none in roughly 34 common murres tested by the state and partners, and officials said the broader mortality event appeared largely unrelated to H5N1 activity. International Bird Rescue also said all Southern California birds tested there had come back negative for bird flu. ### Why are so many of the birds young? Because young seabirds are the bad-breaks version of vulnerable. They’re less experienced at catching prey and less resilient when food gets patchy. State wildlife officials said nearly all of the birds examined were younger birds, and they also noted that 2025 was an unusually good reproductive year — which can leave more juveniles exposed when conditions turn rough. Basically, there may simply be more inexperienced birds running into a suddenly harder ocean. ### What should beachgoers actually do? Don’t try to feed or handle the bird. A starving pelican can look still and helpless, but stress and bad handling can make things worse. Rescue groups want people to report distressed birds quickly so trained staff can intervene, because the longer a bird goes without rescue, the worse its recovery odds get. International Bird Rescue directs people to its Bird HelpLine at 866-SOS-BIRD. ### Is this a one-off? Probably not. That’s the worrying part. California has seen repeated marine heat waves in recent years, and NOAA says large heat waves have occurred in each of the last seven years from 2019 through 2025. Scientists are still sorting out the exact mix of heat, prey shifts, weather, and other stressors, but the bigger pattern is that these disruptions are becoming less unusual. ### Bottom line? The pelicans are the visible part of the problem. When a bird that normally hunts offshore starts collapsing on sidewalks, beaches, or parking lots, the ocean food web is already under strain. What’s happening on the coast this week looks less like an isolated wildlife oddity and more like an early warning from a very hot Pacific.
