On the East Coast, harbor seals are found from the Canadian Arctic to the Mid-Atlantic. 6 Best Places to See Elephant Seals in California Southern California Harbor Seals. Date Released Harbor seals are within the Order Carnivora, which means that they primarily eat meat. This is a great place to see sea lions and seals due to its location and status as a reserve. California Sea Lion | NOAA Fisheries This hunting program ended in 1960. In Alaska, there are the Aleutian Islands, Pribilof Islands, Bristol Bay, North Kodiak, South Kodiak, Prince William Sound, Cook Inlet/Shelikof Strait, Glacier Bay/Icy Strait, Lynn Canal/Stephens Passage, Sitka/Chatham Strait, Dixon/Cape Decision, and Clarence Strait stocks. EF: You do it too early, you disrupt the moms and the pups, which is a really critical time for the seals. Point Reyes has been using the harbor seal as one of the indicators of the condition of the area's marine systems. Once entangled, seals may drown if they cannot reach the surface to breathe, or they may drag attached gear for long distances as they swim, ultimately resulting in fatigue, compromised feeding ability, or serious injury, all of which may lead to reduced reproductive success and even death. This project was designed to gather and synthesize informationabout the ecology of the seals withinIliamnaLake through a combination of aerial surveys, biological sampling, and ethnographic research. Shortly after the pups are weaned, the seals begin their annual molt of their sea worn fur. Today, there are over 150,000 seals (close to the original level), with the majority living off the coast of California. This number will initially be answered by an automated attendant, from which one can opt to access a name directory, listen to recorded information about the park (i.e., directions to the park; visitor center hours of operation; fire danger information; wildlife updates; ranger-led programs; seasonal events; etc. The Bristol Bay stock in Alaska includes a small population of, freshwater harbor seals that live in Iliamna lake. Twelve of these stocks are in Alaska, and the other 4 are the California, Oregon-Washington coastal, Washington inland waters, and the western North Atlantic stocks. No one is sure yet what they are used for but it is believed that they are used to ease hunger pains during their mating and fasting periods. Based. Sometimes a harbor seal may have a reddish colored head or body, which is due to iron oxide deposits on the hair shafts. So the viewing elephant seals is effectively permitted from dawn to dusk. The mother is probably in the water nearby feeding. Our work includes: Learn aboutSeal Ecology and Assessment Research in the Northwest Atlantic. Learn who you should contact when you encounter a stranded or injured marine animal. Never approach or try to save an injured or entangled animal yourselfit can be dangerous to both the animal and you. Harbor seals are one of the most common marine mammals along the U.S. West and East Coasts. Mother harbor seals sometimes raise their pups in nurseriesgroups of mothers and their youngthat help protect the seals from predators. Tomales Point is a harbor seal pupping area, but is not closed. As a species, they've done fairly well in most places, managing to adapt to living in undisturbed areas near humans. Taking a closer look, these are some of the general differences to tell these animals, such as on the harbor seal (left) and California sea lion (right) pictured above. . The California sea lion is the well-known performing "seal" of zoos, circuses, and oceanaria. Adult females forage during lactation. Male California sea lions reach lengths of almost 8 feet in length, and weights of more than 600 pounds. Pups weigh about 24 pounds at birth and are ready to swim within minutes. January is when most of the pups are born. If this is not possible, the second-best option is for vessels to follow voluntary approach guidelines. The population in Mexico occupies both side of the Baja California Peninsula: the west coast has an estimated population of 75,000 87,000, whereas the Gulf of California population is near 30,000. Males do not establish their territories until after the females give birthThe animals tend to be more physically aggressive during this time. Harbor seals can usually be distinguished from elephant seals by size alone. The US stock breeds mainly in the Channel Islands, although some breeding sites may be established in northern California, and females are now commonly found there. At night or in cool weather, they travel farther inland or higher up along the coast. Meet the NOAA Alaska Regions Stranding Response Team! Drakes Estero and the mouth to Drakes Estero are closed to boating, canoeing, and kayaking. The crest begins to emerge at sexual maturity and, although highly variable, is most prominent in full-grown males. Although the cause often remains unknown, scientists can sometimes attribute strandings to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise. Oil spills and energy exploration, During the breeding season, male seals hold territories in the waters adjacent to where females haul out on shore, called maritory. The distribution range has not changed since the exploitation era but population numbers have increased mainly in California where the population estimate is around 238,000. Seal Viewing Seasons - California State Parks Harassment, including repeated exposure to vessel traffic and other disturbance, can degrade important nursery, molting, and haul out areas for harbor seals. Adult females feed between 6.2 to 62 miles from shore, but males may forage as far as 280 miles from shore.5, Reproduction Harbor seals haul out (rest) on rocks, reefs, beaches, and drifting glacial ice when they are not traveling and/or foraging at sea. Chemical contaminants, Harbor seals are at risk of harm in the event of an oil spill. Bull elephant seals average about 1,360 to 2,500 kg (3,000 to 5,500 pounds), while females range in weight from 360 to 545 kg (800 to 1200 pounds). Oil and gas development, commercial and recreational development (including resort development), and increased vessel traffic may displace seals or their prey that would normally use those areas. The most effective way to reduce vessel disturbance is for vessels to stay away from seals. Targeted management actions taken to secure protections for these seals include: Our research projects have discovered new aspects of harbor seal biology, behavior, and ecology and have helped us better understand the challenges that all harbor seals face. California's Channel Islands are an important location in their habitat, where many Harbor Seals live. Baby Seal, California At this state natural reserve, the sound of barking sea lions carries over rocky headlands and echoes in secluded inlets. World map providing approximate representation of the harbor seal range. Is that a seal or a sea lion? Harbor seals can become entangled in fishing gear and other types of marine debris, either swimming off with the gear attached or becoming anchored. Volunteers monitor the population of harbor seals in spring and summer. 415-464-5100 Males are slightly larger than females, and seals in Alaska and the Pacific Ocean are generally larger than those found in the Atlantic Ocean. On a foggy morning, Jim Harvey, a scientist at Moss Landing Marine Laboratories, gives instructions to the biologists, veterinarians, and volunteers who have come to lend a hand. Geo-coordinates: 38.0276, -122.9618. Harbor seals and elephant seals are in the Family Phocidae (the earless seals) so unlike sea lions and fur seals, they do not have external ear flaps on the head, just a small hole where their ear is. The trained "seals" in zoos and aquariums are usually California sea lions. The trained "seals" in zoos and aquariums are usually California sea lions. To understand the health of marine mammal populations, scientists study unusual mortality events. They spend much time sleeping and playing. Her larger study on human-induced effects on seal is still ongoing, however, so she doesn't have her final results yet. The molt period begins around mid-June and extends through July. 5, Habitat Illegal feeding and harassment, However, if a mother is repeatedly disturbed on a site with her pup, she may decide to abandon her pup for the safety of the water, so please be sure to stay well away from any seals you see. We work with volunteer networks in all coastal states to respond to marine mammal strandings including all pinnipeds. In the long run, these contaminants have the potential to do a lot of damage to harbor seals and to other species, like us. Erin Flynn: Theyre doing the work-up right now. In between winter rains, it is often sunny, calm, and cool. Harbor seals are found all along the West Coast of North America, from Baja California, Mexico to the Bering Sea. The actual Elephant Seal Overlook Trail is mostly flat and about 4 feet wide (1.2 meters wide) with a crushed rock surface. Infiltrating the miniscule droplets of oil found in single-celled marine plants called phytoplankton, these particles work their way up the food ladder, first through the organisms that graze on phytoplankton, then to the carnivores. Incidental Take Authorization: Attentive Energy LLC Marine Site Characterization Surveys off New Jersey and New York (2023), Incidental Take Authorization: Chevron Products Company Long Wharf Maintenance and Efficiency Program in San Francisco Bay, CA, Incidental Take Authorization: Atlantic Shores Offshore Wind, LLC's Site Characterization Surveys off New Jersey and New York (2023), Incidental Take Authorization: Bureau of Land Management Stabilization of the Punta Gorda Lighthouse Project in Humboldt County, California (Phase 2). In the United States, NOAA Fisheries has identified 16 stocks of harbor seals. Pups weigh around 11 kg (25 lbs) at birth but when they are weaned they may weigh as much as 22 kg (50 lbs). If you see the seals raise their heads in a startle response, immediately back away so that they do not feel threatened. Where to See Sea Lions in California - American Oceans Inadvertent vessel collisions can injure or kill harbor seals. They are commonly seen resting on rocks and beaches along the coast and on floating ice in glacial fjords with their head and rear flippers elevated in a banana-like position. Seals and sea lions rely heavily on the Channel Islands as their primary home along the California coast. Gregg predicts that the Tomales Bay seals will show lower contaminant levels than those in San Francisco Bay. Harbor seals are vulnerable to vessel collisions throughout their range, but the risk is much higher in some coastal areas with heavy vessel traffic. The stocks of the Gulf of California live in the shallow waters of the north (Northern stock), the tidal islands near the center (Central stock), and the mouth of the bay (Southern stock). Illegal feeding of harbor seals can lead to many problems including habituation, aggression, negative impacts to fisheries, entanglement, injury, and death. Disease, Alaska, If there are large numbers of elephant seals on the beach, the beach . Most spring days are windy. According to the National Park Service, the Channel Islands are home to four different kinds of seals and sea lions: harbor seals, northern elephant seals, northern fur seals, and California sea lions. Most pups are weaned at 12 months of age. NOAA Fisheries is committed to the protection of harbor seals. Jim Harvey: The net boat then does an arc in front of the haul-out site. March through July, the pupping and molting seasons, is an especially vulnerable time for harbor seals. Please use care not to disturb the animals at these places and keep a distance of 90 m (300 feet) away. In 33 days, the pups are weaned, at which time the females mate and then head out to sea to hunt for food and replenish the stores of fat and muscle lost while on the beach. Each stock has experienced different population trends over the past 30 years. Significant breeding rookeries for this species are found on the California Channel Islands.1. Along the West Coast, stocks are stable or unknown and the population in New England appears to be stable. Harbor seals, like all marine mammals, are protected under the Marine Mammal Protection Act. Learn more about the Alaska harbor seal approach guidelines in glacial fjords (PDF, 2 pages). According to the IUCN Red List of Threatened Species, the California sea lion should remain classified as species of Least Concern due to its large and increasing population size.Exploitation during the 19th and 20th centuries caused population reductions. Seal and Sea Lion Viewing - U.S. National Park Service By 1988/1989, about 2,000 elephant seals came ashore at Ao Nuevo, and the number of seals breeding and giving birth on the mainland is still increasing. Seal & Sea Lion Week is March 20-24, 2023. The driveway is composed of asphalt, which has degraded and has become potholed in places. And the more we know about the animals we share our planet with, the better we can take care of all the creatures that call it home. California sea lions breed gregariously between May and August, when they arrive at their breeding rookeries. 93001, Download the official NPS app before your next visit. From 2006 to 2009, Pacific Coast Science and Learning Center (PCSLC) communication interns assisted scientists conducting research through the PCSLC and the San Francisco Bay Area Inventory & Monitoring Network to produce a series of Resource Project Summaries, three of which were about harbor seals. Vessel collisions, Blubber doesn't have many nerve endings, so rotund seals make excellent research subjects because scientists can easily take small samples for contaminant analysis without causing too much trouble for the animal. Non-breeding individuals may gather at marinas, wharves, or even navigational buoys. Harbor seal pelvic bones are fused, preventing them from moving their hind flippers under their pelvis to walk on land like sea lions. She will compare here findings at the two sites to see if differences in seal health exist. They nurse for at least five to six months and sometimes over a year. Please take care NOT to make your presence knowneither visually or audiblywhen you come across an individual or a group of harbor seals when you are on land or on the water. All ages and sexes have contrasting black flippers, naked except for a short stubble of dark fur partially covering the upper surface. On warm days, they lie closer to the water. January is when most of the pups are born. What color is the seal? Pets are prohibited year-round on the Elephant Seal Overlook Trail and on Drakes Beach. It can be a little unsettling for the seal, like being poked and prodded at the doctors office. Stay informed of all the latest regional news around NOAA Fisheries. . They occur on the U.S. East and West coasts. California sea lions breed gregariously between May and August, when they arrive at their breeding rookeries. Become a Harbor Seal Monitoring Docent at Point Reyes National Seashore. Gordon Shetler was our on-scene reporter for this podcast. During this time, seals will spend more time resting onshore because it is energetically taxing. The Great Seal, or the Great Seal of the State of California as it is officially called, is the impression made on "all commissions, pardons and other public instruments to which the signature of the Governor is required" with the attestation of the Secretary of State; the impression, with or without "wafer," is made by a master die and counter . Harbor seals weigh up to 285 pounds and measure up to 6 feet in length. Report a sick, injured, entangled, stranded, or dead animal to make sure professional responders and scientists know about it and can take appropriate action. The distribution range has not changed since the exploitation era but population numbers have increased mainly in California where the population estimate is around 238,000. This research builds on studies since 2002 on ice-associated harbor seals in Disenchantment Bay which have focused on proximate effects such as when, where, and at what distances vessels were causing a disturbance. Scientists observe harbor seals to record their numbers and distribution. The California sea lion is the well-known performing "seal" of zoos, circuses, and oceanaria. They can sleep underwater and come up for air once every 30 minutes. Discover more about the elephant seals by visiting the park'sElephant Sealsand Viewing Elephant Sealspages. The round, mottled bodies and whiskered snouts of harbor seals are a common sight on beaches around Point Reyes and San Francisco Bay. Point Lobos is a state park located on the coast of California in between Los Angeles and San Francisco. The stomach of an average California sea lion may contain as many as 100 pieces of gravel sized rocks. Male California sea lions reach lengths of almost 8 feet in length, and weights of more than 600 pounds. 1, 6, Conservation Status The Marine Mammal Protection Act of 1972 provides federal protection not only to harbor seals, but also to northern elephant seals, California and Steller sea lions, whales, porpoises, sea otters and other marine mammals. The Western Baja California stock mainly breeds near Punta Eugenia and at Isla Santa Margarita. Where are there seals in California? The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere.The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic and North seas. Like adults, seal pups haul out to rest and regulate their body temperature. Then, blood and blubber samples are taken using an anesthetic medication to numb the area, similar to having a mole removed. Check out the San Francisco Bay Area Inventory & Monitoring Network's Harbor Seal Seasonal Monitoring Updates to learn the latest news. Their habit of hauling onto land to rest, give birth and nurse their young, and warm themselves in the sun provides nature enthusiasts a chance for an excellent wildlife sighting, but also makes the harbor seal vulnerable to disturbance. JC: The net has small floats on top and weights on the bottom to help it stink to the seafloor. To learn more about the seals in Tomales Bay, Gregg and a team of researchers from all over North America round up young seals that have just been weaned. This makes sub adult and juvenile males very difficult to distinguish from females. Females are receptive to mating around when the pups are weaned and mating occurs in the water. Expect cool temperatures in March. If you see a lone pup, do not touch, move or otherwise disturb it. Send California 30 days of rain, and there's not much they can do. When dry, the coat of most adult males is dark brown. These seals also haul out in groups to avoid predators and spend less time being watchful for predators than those that haul out alone. In the early 1900's, the seals were hunted almost to the point of extinction, leaving fewer than 100 remaining in the waters off the coast of Baja California. Sea lions have external ear flaps. A male sea lion usually keeps his territory for around 27 days. Harbor seal - Wikipedia JC: The wetsuit-clad crew jumps into the water at the prescribed time to secure the net. The Trillion-Gallon Question: What if California's Dams Fail? But if you do it too late, all the weaned pups go off to exotic places, like Monterey Bay. When they aren't on the beaches of Point Reyes, elephant seals migrate 12,000 to 14,000 miles over the course of a yearin search of food! At night or in cool weather, they travel farther inland or higher up along the coast. 94956. Staggering populations of over 70,000 California sea lions, 5,000 northern fur seals, 50,000 northern elephant seals and 1,100 harbor seals breed and pup on the island each year. While young elephant seals are a uniform gray, harbor seals are typically silver, white or gray, with black spots, although some harbor seals also are black or brown with white spots. By comparing numbers collected over multiple years, scientists can look for trendsi.e., whether the population is increasing, decreasing, or remaining stable during a given period. When stranded animals are found alive, NOAA Fisheries and our partners assess the animals health and determine the best course of action. To reach the Elephant Seal Overlook, park in the Chimney Rock Trailhead parking lot and follow the path/driveway from the parking lot northeast toward the bay as it descends about 50 feet (15 meters) over a distance of about 500 feet (150 meters). Maintain a minimum distance of 90 m (300 feet) from any marine mammal in the water or on the shore to prevent a disturbance. The meat they eat is fish in the nearshore waters of the park, such as herring, anchovies, sardines, hake, flounder, sole, salmon and sculpin. NOAA Fisheries conducts various research activities on the biology, behavior, and ecology of harbor seals. Under the Marine Mammal Protection Act, an unusual mortality event (UME) is defined as "a stranding that is unexpected; involves a significant die-off of any marine mammal population; and demands immediate response." The guidelines suggest that all vessels (from kayaks to cruise ships) should: Alaska Harbor Seal Approach Guidelines in Glacial Fjords brochure, Frequent Questions: Alaska Harbor Seal Approach Guidelines in Glacial Fjords. Females lack a pronounced crest and have a thinner head that slopes more gently to the end of the muzzle. ), or speak with a ranger. Some seals also migrate annually up to 800 km (500 miles) during the winter months to other foraging areas, and then return to Point Reyes to breed and molt their fur. In the fall the juveniles return for a pre-breeding season haul out. This number will initially be answered by an automated attendant, from which one can opt to access a name directory, listen to recorded information about the park (i.e., directions to the park; visitor center hours of operation; fire danger information; wildlife updates; ranger-led programs; seasonal events; etc. Even a temporary disruption stresses the animal by cutting into its time to warm up, rest, and nurture young. New England/Mid-Atlantic, This location even has a trail called "Sea Lion Point Trail." On this trail, you may see sea otters, harbor seals, and sea lions! Breeding takes place a few weeks after birth. When in water, harbor seals propel themselves with their hind flippers in a sculling motion, and steer with their front flippers, whereas sea lions and fur seals propel themselves with their fore-flippers, like wings. Each year the elephant seal population continues to grow. Image. The population has grown and stabilized over the past decade and females give birth to pups around every year. Pups also learn to recognize the smell and vocalizations of their mothers. Come prepared for rain and drizzle to possibly last for several days. Because glaciers in Alaska are experiencing unprecedented rates of ice loss, harbor seals are already coping with reduced ice cover at some tidewater glaciers, which makes them more sensitive to other impacts. So, they're interesting in their own right. In both sexes, the muzzle is dog-like and long, slightly tapering to a moderately blunt end. Introduction These K-rails may block one's view of the elephant seals if one is seated in a wheelchair. 1, 7, Range Individual breeding and molting colonies can number in the thousands in some of these areas. Harbor seals mate in the water. Even on a leash, dogs may threaten seals by barking, so please refrain from taking your pets to areas where seals may be present. The seal gets a mild sedative, making the process a little less stressful. Please note that if you are calling between 4:30 pm and 10 am, park staff may not be available to answer your call.
