Lead author Mike Ford, director of the conservation biology division at the National Oceanic and Atmospheric Administration’s Northwest Fisheries Science Center, found that L41 and J1 between them fathered 37 babies in all three of the southern resident pods. He and J1, who died in 2010, are responsible for fathering more than half of the southern residents born in the past three decades, according to a paternity study. The limited number of breeding whales among the southern residents puts the pods at greater risk of extinction than their numbers alone would indicate. The dwindling numbers have been dangerously low for a while now, due to an increase in marine traffic and pollution as well as a decrease in their primary food source, chinook salmon. Shari Tarantino, president of the Orca Conservancy, said L41's death would leave just 72 animals in the “southern resident” population of orcas that frequents the … A one-year symbolic orca adoption includes:. L41 fathered 21 orca babies with 11 different females, according to genetic research published in 2018 in the scientific journal Animal Conservation. “A decline across consecutive years was of some concern, but at that point he was still within the condition range we have measured him to be in over the years,” Durban wrote in an email. This translation has been automatically generated and has not been verified for accuracy. To survive, the population needs more females. Dr. Andrew Trites, director of the University of British Columbia’s marine mammal research unit, said that males will often separate from their pods, so L41 could just be further away from his group. That indicates there is genetic interchange between the pods, but that males also mate with females in their own pods. Welcome to The Globe and Mail’s comment community. The whales live in a matriarchy. “It’s pretty extreme, you have a couple of males producing a lot of offspring,” Ford said in an interview.

There’s been a problem of inbreeding among the southern resident families. The number of breeding whales in the population has ranged from 12 to 53 over the past 40 years, the analysis found. "Given his age and that he looked a little thin in our January 2019 encounter, we fear he may be gone and consider him missing unless he shows up unexpectedly in an upcoming encounter," scientists with CWR said. L41’s age means he probably wasn’t really contributing to his pod in terms of hunting for food, but that doesn’t mean he won’t be missed. Another southern resident orca, L41, is feared dead, according to the Center for Whale Research. A very few other males have contributed one or two offspring in this population.

My first acquaintance with the Southern Resident killer whale (SRKW) we designated L41 was in 1977, the year after we began the annual Orca Survey of this population that continues to this day. The Center for Whale Research, a non-profit organization in Washington State that has been monitoring the whales for over four decades, said in a report last week that the disappearance is concerning. Members of the L pod seen in Haro Strait on January 24, 2020. Orca Recovery Day 2019 consists of over 70 events across the region where people can work on projects to help our orca population survive.

In 2019, the southern resident killer whale population dropped to 73 members — a number that included L41. But it’s still sad news, “as any of us can relate to [like with] family members, no matter how old they are, they all die too soon.”. The research documented instances of close inbreeding in the population, between parent and offspring, and between siblings. They tend to choose larger and older males, and after J1’s death, L41 was the oldest and biggest of all the southern resident males.
