Wildlife mystery: Why are gray whales swimming into San Francisco Bay in increasing numbers?
Gray whales have been veering off their normal routes along the West Coast and swimming under the Golden Gate Bridge into San Francisco Bay in unprecedented numbers.
Using thousands of photographs of distinctive markings on the whales’ backs to identify them, marine scientists have confirmed that at least 71 different gray whales—and possibly 84 or more—swam into the bay between 2018 and 2023, with some staying for more than two months, raising their risk of being hit by cargo ships, oil tankers or other large vessels.
From 2010 to 2017, only about one or two of the giant marine mammals came into the bay every year. Last year, however, there were at least 16, and in 2019 there were at least 21.
“We think it has a lot to do with the fact that the whales haven’t been getting enough food,” said Bill Keener, a biologist with The Marine Mammal Center, a non-profit group in Sausalito. “They may be weak and resting for a while, or they looking for an alternative food source.”
Some are malnourished, he said.
From 2019 to 2023, 22 gray whales were found dead in or near San Francisco Bay, according to data from The Marine Mammal Center, the California Academy of Sciences and public agencies. Of those, 14 died from unknown causes. Researchers performed studies, called necropsies, on nine of the whales. Six died from malnourishment. Three died from a collision with a ship.
Over the past four years, dead gray whales have been found inside San Francisco Bay off Angel Island, and near Richmond, Rodeo, Hercules, San Leandro, Mountain View, the Port of Oakland, Tiburon, the Berkeley Marina and Martinez.
“They aren’t just near the Golden Gate,” said Keener, who said a slower speed limit for big ships in the bay may be needed. “They are way into the bay, past Angel Island, down to Treasure Island. There’s a lot of ship traffic there.”
Wayward whales have inspired public interest for years.
One lost humpback, nicknamed Humphrey, gained national attention in 1985 and became the subject of children’s books, songs and a movie—drawing crowds of onlookers with binoculars—when he swam into the bay. Humphrey meandered up the Delta to sloughs 25 miles south of Sacramento, staying 26 days before finally returning to the Pacific Ocean as researchers played whale songs from speakers off boats to lure him west.
In 2007, a mother humpback and her calf, nicknamed “Delta and Dawn,” swam into the bay and ventured as far up the Delta as Rio Vista before scientists in boats coaxed them back into the open ocean 10 days later.
There was also a jump in the number of humpback whales that swam under the Golden Gate Bridge pursuing anchovies in from 2016 to 2018. They stayed only a few days each.
But the latest trend with gray whales seems different, researchers say. It could be a sign of stress in the wider population.
The pattern comes amid a big drop in the gray whale numbers off the Pacific Coast in recent years.
Once hunted by whaling ships in the 1800s for their oil until there were only about 1,000 or 2,000 individuals left, gray whales were protected in 1972 when President Nixon signed the Marine Mammal Protection Act. The last whaling company in the United States, the Del Monte Fishing Company, operated at Point Molate in Richmond. It made Kal-Kan dog food out of whales that its crews shot with mechanized harpoon cannons. The company closed in December 1971 as the law was about to take effect.
After whaling was banned in the U.S., numbers of gray whales increased. By 1994, after they reached a healthy population, the Clinton administration removed them from the Endangered Species Act list in what is still considered one of the nation’s major wildlife success stories.
Their population jumped to 27,000 by 2016, according to estimates from NOAA, the National Oceanic and Atmospheric Administration. But then it fell by at least one third by 2022. Hundreds of malnourished whales began to wash up on beaches in Alaska, Washington, Oregon, California and Mexico. Nobody knew why.
Researchers said the die-off from 2018 to 2023, which NOAA called an “unusual mortality event,” was likely due to a shortage of food in the Arctic linked to changes in the amount of sea ice, wind patterns and other factors. Whales eat 3,000 pounds or more of food a day, preferring small, shrimp-like crustaceans known as amphipods, along with worms and other tiny creatures that they scoop from the sea floor.
Last year, gray whale numbers began to rebound to as many as 21,000. NOAA declared an end to the “unusual mortality event” in November. Scientists are watching carefully to see if the change is temporary or permanent.
The roller coaster population—and weird detours into San Francisco Bay—could be related to climate change, or it could be part of the gray whale’s natural population fluctuations, said John Calambokidis, a research biologist with Cascadia Research, in Olympia, Washington.
“What is a natural cycle?” he said. “Is this normal? Or something unusual? The ecosystem in the Arctic has changed very rapidly. That’s one reason this has scientists’ attention.”
One thing is clear: The gray whales coming into San Francisco Bay are heading north as part of their annual migration from Baja, Mexico where they mate and breed, and turning right under the Golden Gate Bridge instead of continuing north to Alaska where they stock up on food during the summer months.
A lot is known about the latest trend because one researcher, Josephine Slaathaug, of the Marine Mammal Center, painstakingly sorted through more than 11,000 photographs of gray whales in San Francisco Bay last year. She built a database, identifying individual whales from photos taken on whale watching boats, the shoreline, and the center’s boats. She showed the animals are most common in March and April, and stayed in the bay between 13 and 75 days.
Slaathaug, a masters student at Sonoma State University, won a prestigious fellowship in April from the National Science Foundation as she expands the study in the coming years. One key question: Will the number of gray whales in the bay go down if their food in the Arctic recovers, and the West Coast population increases?
“We don’t understand all the drivers,” she said. “We have preliminary data. But we do know that with all the ships, the bay is not a very safe place for the whales.”

Bay Area High School baseball fans are treated to a rare opportunity Saturday (April 18) with three games at Oracle Park, home of the San Francisco Giants, including the famed Bruce-Mahoney clash between West Catholic Athletic League rivals St. Ignatius and Sacred Heart Cathedral.
The first pitch of the 20th annual Dante Benedetti Baseball Classic starts at 11 a.m. and pits two more San Francisco private schools as University (9-7), winners of four straight, taking on Riordan (5-11).
That will be followed by the Bruce-Mahoney game at 2:30 between St. Ignatius (12-5, 4-2 WCAL) and the Irish (7-10, 1-5) and finished off with a North Coast Section clash between North Bay’s Marin Catholic (9-7) against Acalanes (7-6-1).
The Benedetti Classic, founded by Dante’s Boys Foundation board member Tom Lounibos and Giants president Larry Baer, benefits the DBF which honors the spirit of Benedetti who for nearly 40 years owned San Francisco’s Mr. Baseball nickname for his kindness and generosity to baseball-playing youth in the area.
Among their philanthropic efforts are glove and baseball equipment drives, field renovations and contributions to scholarships and sponsorships.
After starting the season 0-4 — three of those losses were by one run — University, under head coach Andrew Suvunnachuen, has found its way, winning the last four, all in Bay Counties League play, by a combined 51-6 count over Lick-Wilmerding (16-1 and 11-3) and San Domenico (13-2 and 11-0).
Senior catcher and pitcher Jett Messenger leads the way with a .447 average, while getting on base at a .638 rate. He also leads the team with 20 stolen bases. Junior third baseman Tate Gebhart is hitting .419, while Leo Felder and Behbart share the RBI lead with 15 each.
Junior Matthew Foley is 3-2 on the mound with a 2.38 ERA and 25 strikeouts in 17.2 innings.
Riordan, under second-year head coach Craig Sargent, was 5-5 in nonleague games but lost six straight in the rugged WCAL, losing two tough games this week to Mitty (3-2 and 7-4). Junior third baseman and pitcher Santiono Williams leads the team in batting average (.371), on-base percentage (.488) and stolen bases (nine). He’s also been the team’s top pitcher at 4-2 with a 2.84 ERA.
The teams have split two previous games in their history, with Riordan winning 2-0 in 2023 and University prevailing 5-0 in 2021.
St. Ignatius, led by ninth-year head coach Brian Pollzzie, has already secured the Bruce-Mahoney trophy with four straight wins — one each in football, girls volleyball, boys basketball and girls basketball — but this rivalry is always spirited.
The Wildcats, who are ranked fourth in the Bay Area by the San Francisco Chronicle, are coming off a tough 3-0 home loss to No. 2 St. Francis on Friday after beating the host Lancers 10-6 on Tuesday.
The team is led by Stanford-bound Archer Horn, who is hitting .486 with four home runs and a .604 on-base percentage. The shortstop and pitcher also has not allowed an earned run in three pitching appearances while registering one save.
Pitching is a team’s strength with a 2.59 ERA, led by a brigade of strong arms including Leo Rhein (2-0, 2.38), Tycco Giometti (2-1, 2.62), Charlie Stecher 1-1, 0.72) and Chase Gordon (1-0, 2.80). The team is missing standout Finn Demuth, out of the season after undergoing Tommy John surgery.
Sacred Heart Cathedral, led by fourth-year head coach Gregg Franceschi, has scored 60 runs on the season and given up 61. The Irish are coming off two losses to eighth-ranked Valley Christian (5-2 and 10-1).
They are led offensively by junior outfielder Brody O’Sullivan (.381) and senior infielder Jacob Vines (.378). Johnny Nepomuceno and Max Nylander are other run-producers. Zach Stallworth (37 strikeouts, 29.2 innings) and Cooper Rogers Lewis (0.25 ERA) have been the team’s top pitchers.
The series has been remarkably close since 2005 with Sacred Heart Cathedral holding a 27-20 edge, though St. Ignatius won both games last season (5-0 and 6-3) after the Irish won 9-7 and 1-0 in 2024.
Marin Catholic hopes to get back to winning after starting the season 9-1, but have since lost six straight, four in Marin County Athletic League play, including 4-2 to Novato on Thursday. Senior outfield Luke Martin is the team’s leading hitter at .478 while senior infielder and pitcher Cooper Mitchell is at .455. Senior infielder Walker Untermann leads the team with 15 RBIs.
Acalanes is at the other end of the spectrum, winners of five of six after a 2-5-1 start. Junior infielder Tyler Winkles, also a highly recruited quarterback in football, leads the team with a .383 average and nine stolen bases. Riley Gates (2-3, 2.49 ERA, 30 strikeouts) is the team’s top pitcher.
The teams have played three times, all since 2022, with Marin Catholic owning a 2-1 lead. Acalanes won last year’s game 8-7.

Chinatown fatal crash victim ID’d, safety measures proposed
The victim killed in Friday’s Chinatown crash was identified Monday by the medical examiner as Cutberto Zamora-Martinez, 49, of San Joaquin County. At a meeting on Monday, city officials said the cause of the crash is still under investigation.
SAN FRANCISCO – A 76-year-old man has been arrested on suspicion of vehicular manslaughter and speeding following a crash in San Francisco’s Chinatown that killed a man working in the area.
Zhuo Ming Lu, 76, is accused in the March 27 crash that left 49-year-old Cutberto Zamora-Martinez, of San Joaquin County, dead.
Suspect was trying to park
What we know:
Authorities said Lu was attempting to park near Grant Avenue and Jackson Street when his vehicle jumped the sidewalk and crashed into the landmark New Lung Ting Café, also known as the Pork Chop House. The vehicle also struck two pedestrians, including Zamora-Martinez.
Zamora-Martinez died from his injuries.
He had been working in the area, according to a GoFundMe page. A San Francisco Police Department source close to the investigation told KTVU the victims were carpet installers arriving for work.
The fundraising page described Zamora-Martinez as a husband and father who was the sole provider for his family and “a humble man who wanted the best for his family.”
Before his arrest, Lu had been cooperating with investigators. Authorities have not confirmed what caused the crash.
Some residents questioned whether the driver’s age or a possible confusion between the brake and gas pedals may have been factors.
“Maybe if people hit a certain age, you got to get retested for your driver’s license is something I was thinking about,” said Keith Hong, who works next door to the crash site.
Another case involving an elderly driver
Big picture view:
In an unrelated case, Mary Fong Lau, 80, was sentenced to probation after killing a family of four, two parents and their young children. in March 2024. Authorities said Lau struck the victims as they waited at a Muni stop on their way to the zoo.
Lau pleaded no contest to four felony counts of vehicular manslaughter, and a judge accepted the plea. A Superior Court judge cited her age, remorse and lack of criminal history in the sentencing decision.
She was placed on probation for two years, banned from driving for three years and ordered to complete 200 hours of community service.

San Francisco first came to know chefs Laura and Sayat Ozyilmaz through their pop-up Istanbul Modern, and later through their breakthrough Presidio restaurant Dalida. The duo’s success is grounded in their take on Eastern Mediterranean food, which they made a conscious decision to champion 10 years ago.
Fast-forward to 2026, and now Laura is taking on a personal project of her own, with Sayat by her side, placing foods from Mexico’s Guerrero and Sinaloa center stage at Maria Isabel. It’s a refreshing menu that combines both Mexican and local ingredients, through the lens of the Ozyilmazes cooking backgrounds.
Reservations are released on OpenTable 30 days in advance, but Laura confirmed that they do take walk-ins depending on space. Smaller parties or solo diners might have better luck sliding in, thanks to the counter in the brighter, “Maria” portion of the restaurant.
The cocktails from consulting bar director Evan Williams are always worth a glimpse, whether at Dalida or at Maria Isabel. They’re well-balanced and have incredible depth and technique behind them. That being said, the team sourced wines from woman-led wine brands such as LOTIS Wines and Amevive Wine, if you’re looking to explore past the usual selections you’ll see elsewhere.
