Grieving Orca Mother Carries Dead Calf for 'Heartbreaking' 8th Day
Researchers scanned the waters all day before the mother orca and her deceased newborn turned up near British Columbia's Southern Gulf Islands.
"I am relieved we see her, that she is healthy and swimming strongly, and that she is with her family," Taylor Shedd of Soundwatch, which has been monitoring the pod, told the publication. "But it is so emotional that she is so caring. It boggles my mind. To carry it is hard for her physically and mentally. It is just heartbreaking."
The baby whale was born near Victoria, British Columbia on July 24. The newborn was seen alive and swimming with its mother, Tahlequah, and other members of its pod near Clover Point on the Victoria shoreline in the mid-morning but died a short time after, according to the Washington-based Center for Whale Research.
"The baby's carcass was sinking and being repeatedly retrieved by the mother who was supporting it on her forehead and pushing it in choppy seas toward San Juan Island, USA," the center said in a press release. "The mother continued supporting and pushing the dead baby whale throughout the day until at least sunset."
It's not unusual for orcas to carry their dead offspring for about a day or so, researchers told NPR. However, Jenny Atkinson, executive director of The Whale Museum on San Juan Island, noted this is the longest period researchers have observed.
Researchers are also concerned about Tahlequah's health.
"I am so terrified for her well-being," Deborah Giles, a research scientist for University of Washington Center for Conservation Biology and research director for nonprofit Wild Orca, told The Seattle Times. "She is a 20-year-old breeding-age female, and we need her."
The story of the "grieving" orca mother has captured international attention as the population of southern resident killer whales fights to survive.
In June, the Center for Whale Research reported that a 23-year-old male orca was missing and presumed dead, leaving the community of orcas with just 75 individuals remaining.
The population grew 48 percent to a high of 98 in 1995, but has since fallen to their lowest number in 30 years.
Experts say their decline is due to pollution, underwater noise and disturbances from boat traffic, and lack of their favored prey, Chinook salmon. Recent deaths, particularly among calves, mothers and pregnant whales, appear to be driven by food scarcity, according to the Center for Whale Research.
"The larger environmental question reflected in the J35 story is that both the USA and Canada MUST redouble efforts to restore wild salmon (particularly Chinook) throughout Washington State and British Columbia for a food supply for the SRKW in this region," the center tweeted last week, citing a statement from founder and senior scientist Ken Balcomb.
"The diets of southern resident orcas consist largely of Chinook salmon, but the Chinook are listed on federal and state endangered species lists," Inslee's office stated. "If the Chinook population continues to decline, the southern resident orca population will follow."

Oil rigs around the world keep pulling crude oil out of the ground, but the global pandemic has sent shockwaves into the market. The supply is up, but demand has plummeted now that industry has ground to a halt, highways are empty, and airplanes are parked in hangars.
Under an agreement negotiated by community groups — represented by NRDC and the Pennsylvania Utility Law Project — the Pittsburgh Water and Sewer Authority (PWSA) will remove thousands of lead water pipes by 2026 in order to address the chronically high lead levels in the city's drinking water and protect residents' health.

So, they finally went and did it — the Trump administration just finalized a rule to undo requirements on manufacturers to improve fuel economy and reduce greenhouse gas emissions from new passenger cars and trucks. Even with the economy at the brink of a recession, they went forward with a policy they know is bad for consumers — their own analysis shows that American drivers are going to spend hundreds of dollars more in fuel as a result of this stupid policy — but they went ahead and did it anyway.

A blood test that screens for more than 50 types of cancer could help doctors treat patients at an earlier stage than previously possible, a new study shows. The method was used to screen for more than 50 types of cancer — including particularly deadly variants such as pancreatic, ovarian, bowel and brain.
Preliminary data from the Centers for Disease Control showed a larger number of young people coming down with COVID-19 than first expected, with patients under the age of 45 comprising more than a third of all cases, and one in five of those patients requiring hospitalization. That also tends to be the group most likely to use e-cigarettes.
