List Of Northern Resident Orca Pods
Northern resident orcas, also known as northern resident killer whales (NRKW), are one of four separate, non-interbreeding communities of the exclusively fish-eating ecotype of orca in the northeast portion of the North Pacific Ocean. They live primarily off the coast of British Columbia (BC), Canada, and also travel to southeastern Alaska and northern Washington state in the United States. The northern resident population consists of three clans (A, G, R) that consists of several pods with one or more matrilines within each pod. The northern residents are genetically distinct from the southern resident orcas and their calls are also quite distinct. Social structure Like the Southern residents, the Northern residents live in groups of matrilines. A typical Northern resident matriline group consists of an elder female, her offspring, and the offspring of her daughters. Both males and female orcas remain within their natal matriline for life. Matrilines have a tendency to split ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecotype
Ecotypes are organisms which belong to the same species but possess different phenotypical features as a result of environmental factors such as elevation, climate and predation. Ecotypes can be seen in wide geographical distributions and may eventually lead to speciation. Definition In evolutionary ecology, an ecotype,Greek: ''οίκος'' = home and ''τύπος'' = type, coined by Göte Turesson in 1922 sometimes called ecospecies, describes a genetically distinct geographic variety, Population biology, population, or Race (biology), race within a species, which is genotypically Adaptation, adapted to specific environmental conditions. Typically, though ecotypes exhibit Phenotype, phenotypic differences (such as in Morphology (biology), morphology or physiology) stemming from environmental heterogeneity, they are capable of interbreeding with other geographically adjacent ecotypes without loss of fertility or vigor.''Ecology: From individuals to ecosystems'' by Begon, Townsen ...

Dixon Entrance
The Dixon Entrance () is a strait about long and wide in the Pacific Ocean at the Canada–United States border, between the U.S. state of Alaska and the province of British Columbia in Canada. The Dixon Entrance is part of the Inside Passage shipping route. It forms part of the maritime boundary between the U.S. and Canada, although the location of that boundary here is disputed. Etymology The strait was named by Joseph Banks for Captain George Dixon, a Royal Navy officer, maritime fur trader, and explorer, who surveyed the area in 1787. Geography The Dixon Entrance lies between Clarence Strait in the Alexander Archipelago in Alaska to the north, and Hecate Strait and the islands known as Haida Gwaii (the Queen Charlotte Islands) in British Columbia British Columbia is the westernmost Provinces and territories of Canada, province of Canada. Situated in the Pacific Northwest between the Pacific Ocean and the Rocky Mountains, the province has a diverse geography, with ru ...

Orcas
The orca (''Orcinus orca''), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. The only extant species in the genus '' Orcinus'', it is recognizable by its black-and-white-patterned body. A cosmopolitan species, it inhabits a wide range of marine environments, from Arctic to Antarctic regions to tropical seas. Orcas are apex predators with a diverse diet. Individual populations often specialize in particular types of prey, including fish, sharks, rays, and marine mammals such as seals, dolphins, and whales. They are highly social, with some populations forming stable matrilineal family groups (pods). Their sophisticated hunting techniques and vocal behaviors, often unique to specific groups and passed down from generation to generation, are considered to be manifestations of animal culture. The International Union for Conservation of Nature (IUCN) lists the orca's conservation status as data deficient as multiple orca types may ...

Namu (orca)
Namu (died July 9, 1966) was a male orca unintentionally captured in 1965 from the C1 Pod of the northern resident community. He was the first captive orca to perform with a human in the water. He was the subject of much media attention, including a starring role in the 1966 film '' Namu, the Killer Whale''. Namu's captivity introduced thousands of people to orcas, and soon aquariums all over the world sought to establish captive orcas in their parks. History In June 1965, William Lechkobit discovered a 22-foot (6.7m) male orca in his floating salmon net that had drifted close to shore near Namu, British Columbia. The orca was sold for $8,000 to Ted Griffin, owner of the Seattle Marine Aquarium; it ultimately cost Griffin much more to transport Namu south to Seattle. While in captivity, Namu ate 400 pounds of salmon a day. Namu was a popular attraction at the Seattle Marine Aquarium, and Griffin soon captured a female orca to be a companion for Namu. The female, named Shamu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corky (killer Whale)
Corky II (born ), often referred to as just Corky, is a female captive orca from the A5 Pod of northern resident orcas. At approximately the age of four, Corky was captured from Pender Harbour off the coast of British Columbia on 11 December 1969. She has lived at SeaWorld San Diego in San Diego, California since 21 January 1987. As of 2024, she is the oldest and longest kept captive orca. SeaWorld San Diego celebrates her birthday on January 1st every year. Early life Corky was born in 1965. Her mother, designated A23, nicknamed "Stripe", was born in 1948 and died in 2000. Corky, along with a young unnamed male and a young female later named Patches, were sold to Marineland of the Pacific, in Palos Verdes, California. Corky is the only surviving captive orca from the Pacific Northwest. As a member of the northern resident orca community, she has been given the alphanumeric code A16. Captivity Corky II received her name after the park's original orca, ''Corky I'' (1965 – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A5 Pod
A5 Pod is a name given to a group of orcas (''Orcinus orca'') found off the coast of British Columbia, Canada. It is part of the northern resident orcas population—a name given to the fish-eating orcas found in coastal waters ranging from mid-Vancouver Island in British Columbia up through Haida Gwaii and into the southeastern portions of Alaska. The orcas of the Northern Resident community are divided into vocally distinctive clans known as the A clan, the G clan, and the R clan. Members of the A5 Pod belong to the A clan. As of 2024, A5 Pod consisted of ~15 members.https://www.orcaconservancy.org/sightings-report/february-24-2024-a5-pod-bowen-island-bc Over time, studies showed that these congregations of orcas did not make up a complete, distinctive pod. Rather, they were matrilines—a mother and her offspring up to the fourth generation. However, matrilines within a pod frequently socialize with one another, more so than with orcas from another pod—thus still making up a ...

Springer (orca)
Springer (born ), officially named A73, is a wild orca from the List of northern resident killer whale pods, Northern Resident Community of orcas, which frequents the waters off the northern part of Vancouver Island every summer. In January 2002, Springer, then a calf developmentally equivalent to a human toddler, was discovered alone and emaciated some 250 miles from the territory of her family (called a "pod"). Experts identified Springer by her whale song, vocal calls that are specific to her pod, and by examining photographs of her eye patch. They were also able to determine where Springer's pod was currently located. After months of heated public debate, a decision was made by the United States National Marine Fisheries Service (NMFS) to capture the young orca and attempt to reintegrate her into her pod. On June 12, 2002, Springer was captured and moved to a seapen in Manchester, Washington. On July 13, after medical treatment and rehabilitation, Springer was transported to Jo ...

A4 Pod
A4 pod is a killer whale family in British Columbia. As of March 2013, it consists of three matrilines and 15 members and is the family of Springer, the first orca to be successfully reintroduced to the wild after being handled by humans. A4 pod is part of the northern resident orcas found in coastal waters ranging from mid-Vancouver Island to southeastern Alaska up through Haida Gwaii (formerly the Queen Charlotte Islands). The community is made up of three clans known as A, G and R clans, each possessing a distinctive dialect and consisting of several related pods. A4 pod belongs to the biggest clan, A clan. Early research and naming A4 pod was one of the first pods photo-identified by Michael Bigg and Graeme Ellis in 1972. At that time, it was called “The Six” and was first thought to be part of A pod. When it became clear to researchers that these whales spent a significant amount of time apart from the rest of the group and had just happened to be travelling together when ...

A30 Matriline
The A30 matriline is the name given to the most commonly seen orca matriline in British Columbia. The matriline is currently made of 3 generations, with a total of 12 individuals. It is one of the 3 matrilines in A1 pod, one of the 10 pods of the A-clan. The matriline was present in over 60% of all of the encounters in the Johnstone Strait region, making it one of the best known matrilines. The group's size has increased, from 6 in the mid-1970s to 10 as of 2013 then 12 in 2017. It is most frequently seen in Johnstone Strait from late spring to early fall, often traveling with other pods of the Northern Resident Community.
