“Great news!!! A new calf was documented today in J pod! The calf, designated J53, was seen traveling with J17. This is the third calf in J pod this year! More information will be coming soon . . . .” The Center for Whale Research
The Center for Whale Research reports that J50 was born in December (so she is a 2014 calf). J51, J52 and now J53 are all 2015 calves. L121, and L122 are also 2015 calves.
Southern Resident killer whales are the only known resident population to occur in the U.S. Southern residents are comprised of three pods: J, K, and L pods. The Southern Residentsare considered one “stock” under the Marine Mammal Protection Act (MMPA) and one “distinct population segment” (therefore, “species”) under the Endangered Species Act (ESA).
The Southern Resident Killer Whale population is currently estimated at about 80 whales, a decline from its estimated historical level of about 200 during the late 1800s.
Beginning in the late 1960s, the live-capture fishery for oceanarium display removed an estimated 47 whales and caused an immediate decline in Southern Resident numbers. The population fell an estimated 30% to about 67 whales by 1971. By 2003, the population increased to 83 whales. Due to its small population size, we listed this segment of the population as endangered under the Endangered Species Act (ESA) in 2005 and designated critical habitat in 2006.
Their range during the spring, summer, and fall includes the inland waterways of Washington state and the transboundary waters between the United States and Canada. Relatively little is known about the winter movements and range of the Southern Resident stock. However, in recent years, they have been regularly spotted as far south as central California during the winter months and as far north as Southeast Alaska, through our Northwest Fisheries Science Center’s satellite tagging work.
