Tahlequah, a famous orca known for carrying the body of her dead calf for 17 days in 2018, has lost another calf and is again displaying the behavior.
A mother orca who famously carried the body of her dead newborn for 17 days in 2018 has lost another calf, and researchers say she is again carrying the body in an apparent act of grief. The Center for Whale Research said in a New Year's Day post on social media that the mother known as Tahlequah, or J35, has now lost two of her four documented calves. The centre had announced on Dec.
21 that the new female calf was travelling with J pod in the Puget Sound area, on the northwest coast of Washington state. The pod also frequents British Columbia waters. But the organization expressed concern about the calf's health, and on Wednesday said it had confirmed the calf had died, although a second newborn was also observed with the pod. Brad Hanson, a research scientist with the National Oceanic and Atmospheric Administration's Northwest Fisheries Science Center, told a news conference Thursday that researchers are not yet sure why the calf died, but a necropsy likely won't be possible. 'Given that J35 is very attached to it, the likelihood of us being able to recover the calf is fairly low,' he said. Hanson said researchers are concerned about Tahlequah's welfare as she continues to carry the calf's body, draped over the top of her head. 'That essentially results in a lot more drag, and so her energy expenditure is going to be fairly significant,' he said, noting it may also make foraging difficult during a time of year when fish availability is more limited. 'It is a concern that she was spending a lot of energy to try to take care of this calf that she has lost.' But, he said, she is not lagging behind her pod. 'She's still integrated as part of the group.' The Center for Whale Research, based in Washington state, says the death of any calf among the endangered southern resident killer whale population is'a tremendous loss,' but the latest is'particularly devastating' because she was a female and because of J35's histor
