Known forEntering San Francisco Bay during annual migration in 1985 and 1990

Humphrey the Whale is a humpback whale which twice deviated from his Mexico to Alaska migration by entering San Francisco Bay. [1] [2] This behavior is unusual for a humpback whale, and Humphrey attracted wide media attention when entering the bay in both 1985 and 1990. Both of his bay incursions resulted in rescue by the Marine Mammal Center, based in Marin County, California, assisted by the United States Coast Guard and hundreds of other volunteers.


The last sighting of Humphrey was in the vicinity of the Farallon Islands in 1991.


The humpback whale is a mammal which belongs to the baleen whale suborder. An adult usually ranges between 12–16 m (39–52 ft) long and weighs approximately 36,000 kilograms (79,000 pounds), or 36 tonnes (40 short tons ). [3] It is well known for its breaching, its unusually long front fins, and its complex whale song. [4] The humpback whale lives in oceans and seas around the world.

Humpback whales have a stocky body with well-defined humps and black upper elements. The head and lower jaw are covered with knobs called tubercles, which are actually hair follicles and are characteristic of the species. The tail flukes, which are lifted high in the dive sequence, have wavy rear edges.

Individual humpbacks have unique patterns on their long black and white tail fin and pectoral fins which allow scientists to positively identify them.

Humphrey's journeys inland


In 1985, a 40-foot-long (12-meter) humpback entered San Francisco Bay and was followed closely on the evening news by Bay Area television stations. [5] After a few days in the bay, the whale, nicknamed Humphrey, [6] swam up the Sacramento River into a freshwater habitat. The whale, first spotted at Oakland's Outer Harbor October 10, 1985, [6] swam up the Carquinez Strait, the Sacramento River and under the Rio Vista Bridge to a dead-end slough 69 miles (111 kilometers) from the ocean. [7] [8]

Numerous attempts to coax him back to the ocean failed. One initial attempt involved playing sounds of orcas to frighten Humphrey into leaving. [9] Another attempt was made using a "sound net" in which people in a flotilla of boats made unpleasant noises behind the whale by banging on steel pipes, a Japanese fishing technique known as "oikomi". [7] Several weeks of being trapped in the fresh water of the Sacramento Delta brought signs of physical stress in the whale. His skin was graying [9] and he was becoming more and more listless. None of the traditional herding techniques were working, and Humphrey appeared to be dying.

As a last-ditch effort to save the whale, Louis Herman, a researcher of humpback whales, postulated that it would be possible to lure it out by playing acoustic recordings of whale social and feeding sounds. [9] Dr. Bernie Krause, an acoustician, offered the recordings he had made of humpback whale feeding songs as a possible way to lure him out. [6] However, to get the sounds into the water required a powerful speaker and amplification system that only the Navy was likely to have. Krause contacted Greg Pless who was in charge of the underwater acoustics research laboratory for the Naval Postgraduate School in Monterey, California, where one of the few high-power J-11 underwater transducers existed in the country. Pless and his colleague Dale Galarowicz quickly gained Navy permission and rushed the equipment to Rio Vista where Humphrey was last seen.

Early the next morning, the equipment was loaded onto the private yacht, Boot Legger, donated by its owner for the rescue effort. Directed to the location in the slough where Humphrey was last seen, the speaker was lowered over the side of the boat, the sounds were played, and Humphrey emerged from the water at the bow of the ship. The captain quickly started down the river with Humphrey close in tow. With the assistance of numerous fish and wildlife agencies, including the Army's 481st Transportation Company (Heavy Boat), the crew led him the many miles back down the Sacramento river, alternately playing and not playing the whale songs to keep his interest. Large numbers of spectators lined the banks of the river.

As they approached the San Francisco Bay and the water gained in salinity, Humphrey became visibly excited and began sounding. Though the crew lost sight of him that night, they picked him back up in the morning and led him out through the Golden Gate bridge into the Pacific Ocean on November 4, 1985, at 4:36 p.m. [9] The town of Rio Vista later erected a commemorative granite marker at City Hall at the east end of Main Street. [7] [10] A restaurant in Antioch was named Humphrey's in the whale's honor. The restaurant has been remodeled and it changed its name to Smith's Landing Seafood Grill. [11]

Humphrey stayed a considerable time in 1990 in the embayment immediately north of Sierra Point in Brisbane, California where occupants of the Dakin Building could observe his antics. Humphrey became beached on a mudflat in San Francisco Bay to the north of Sierra Point and to the south of Candlestick Park. [12] He was extricated from the mudflat with a large cargo net and support from the Marine Mammal Center and a U.S. Coast Guard boat.

This time, he was successfully guided back to the Pacific Ocean using a combination of "oikomi" simultaneously with the broadcast of attractive sounds of humpback whales preparing to feed from a boat headed towards the open ocean. Researchers Louis Herman and Bernie Krause led a team of scientists who used sound recordings of natural whale feeding vocalizations to guide Humphrey back to safety. These sounds were produced for a swimming trajectory of 50 miles (80 km) until Humphrey reached the Pacific Ocean, sometimes attaining speeds of 30 miles per hour (48 km/h). [13]

Later sightings

Cascadia Research Collective spotted Humphrey in 1986, 1987 and 1988 outside the Bay. [14] [15]

Humphrey has been seen only once since the second misadventure, at the Farallon Islands in 1991.

Humpback whale Large baleen whale with long pectoral fins and a knobbly head

The humpback whale is a species of baleen whale. It is one of the larger rorqual species, with adults ranging in length from 12–16 m (39–52 ft) and weighing around 25–30 t. The humpback has a distinctive body shape, with long pectoral fins and a knobbly head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song lasting 10 to 20 minutes, which they repeat for hours at a time. All the males in a group will produce the same song, which is different each season. Its purpose is not clear, though it may help induce estrus in females.

Transportation in the San Francisco Bay Area Overview of transportation in the San Francisco Bay Area, California, United States

People in the San Francisco Bay Area rely on a complex multimodal transportation infrastructure consisting of roads, bridges, highways, rail, tunnels, airports, seaports, and bike and pedestrian paths. The development, maintenance, and operation of these different modes of transportation are overseen by various agencies, including the California Department of Transportation (Caltrans), the Association of Bay Area Governments, San Francisco Municipal Transportation Agency, and the Metropolitan Transportation Commission. These and other organizations collectively manage several interstate highways and state routes, two subway networks, two commuter rail agencies, eight trans-bay bridges, transbay ferry service, local bus service, three international airports, and an extensive network of roads, tunnels, and bike paths.

The Marine Mammal Center

The Marine Mammal Center (TMMC) is a private, non-profit U.S. organization that was established in 1975 for the purpose of rescuing, rehabilitating and releasing marine mammals who are injured, ill or abandoned. It was founded in Sausalito, California, by Lloyd Smalley, Pat Arrigoni and Paul Maxwell. Since 1975, TMMC has rescued over 23,000 marine mammals. It also serves as a center for environmental research and education regarding marine mammals, namely cetaceans, pinnipeds, otters and sirenians. Marine mammal abandonment refers to maternal separation; pups that have been separated from their mother before weaning. At the center, they receive specialized veterinary care: they are diagnosed, treated, rehabilitated and ideally, released back into the wild. Animals in need of assistance are usually identified by a member of the public who has contacted the center. These animals represent the following major species: California sea lions, northern elephant seals, Pacific harbor seals, northern fur seals and southern sea otters. On a few occasions, TMMC has taken in Guadalupe fur seals, Steller sea lions and bottlenose/Pacific white-sided dolphins. The only non-mammals that TMMC takes in are sea turtles.

Ferries of San Francisco Bay

San Francisco Bay in California has been served by ferries of all types for over 150 years. John Reed established a sailboat ferry service in 1826. Although the construction of the Golden Gate Bridge and the San Francisco–Oakland Bay Bridge led to the decline in the importance of most ferries, some are still in use today for both commuters and tourists.

Mori Point

Mori Point is a 110-acre (0.4 km2) park located in Pacifica, California that is part of the Golden Gate National Recreation Area (GGNRA). Mori Point itself is a bluff next to the Pacific Ocean that provides scenic views of the peninsula coastline. In addition to the bluff and ridge, Mori Point contains a few small ponds and wetlands. Trails, many newly built, connect the ridgeline to the entrances to the park and to Sharp Park beach. A portion of the California Coastal Trail will run through Mori Point.

Delta and Dawn

Delta and Dawn, also known as the Delta whales, were two humpback whales, a mother and her calf, which entered San Francisco Bay in early May 2007. They swam up the Sacramento River approximately 90 nautical miles (170 km) upstream from the Golden Gate, about 20 miles (32 km) further inland than Humphrey the Whale had gone two decades earlier. Under the Endangered Species Act, California state officials were required to rescue the animals. Their journey was thought to be the longest freshwater incursion by humpback whales.
