Nearly six years ago, an orca mother drew international attention when she carried her dead calf<\/a> for 17 consecutive days. Now, sadly, the whale seems to be repeating what researchers say is a show of grief with another newborn that has died. <\/p>\n\n\n\n

The mother whale, known as J35 and also as Tahlequah, was first spotted with a new calf\u2002<\/a>on Dec. 20. But on Wednesday, researchers from the National Oceanic and Atmospheric Administration photographed her off West Seattle with the baby whale\u2019s carcass on her head. <\/p>\n\n\n\n

\u201cWe were able to confirm J31 had lost the calf and she was pushing it around on her head,\u201d Brad Hanson, a research scientist with the NOAA Fisheries Northwest Fisheries Science Center, said at a news conference Thursday. <\/p>\n\n\n\n

He added that when the calf appears to sink, \u201cit looks like she\u2019ll do a high arch dive to go down and recover the calf, and whether or not she\u2019s pushing it at that point or grabbing it, we\u2019re not real sure.\u201d<\/p>\n\n\n\n

Scientists said they think Tahlequah is most likely carrying the deceased calf as an expression of grief. Joe Gaydos, the science director of the SeaDoc Society, a marine research organization, said at the news conference that whales have hardwiring similar to that of humans and other large, social mammals that live for a long time.<\/p>\n\n\n\n

\u201cWe have the same neurotransmitters that they have. We have the same hormones that they have. Why shouldn\u2019t we also have the same emotions that they have? We don\u2019t have the market cornered on emotions. And so I think it\u2019s fair to say that she is grieving or mourning,\u201d Gaydos said, adding that similar behavior has been observed in dolphins and nonhuman primates. <\/p>\n\n\n\n

J35 is part of a critically endangered subpopulation of whales known as southern resident killer whales. With the death of Tahlequah\u2019s calf and the recent birth of a different orca, the group\u2019s number is at just 73. <\/p>\n\n\n\n

Over the years, Tahlequah has had two calves that survived, both males, one of them born in 2020.<\/p>\n\n\n\n

The southern residents are given tracking numbers by the Center for Whale Research and are closely observed by researchers, photographers and whale watchers \u2014 particularly when they\u2019re near communities along Puget Sound, like Seattle.<\/p>\n\n\n\n

Scientists have been following the deceased calf\u2019s story for several weeks. Hanson said that after citizen scientists first noticed the female calf, called J61, NOAA researchers spotted her themselves on Dec. 23. They were concerned about the calf\u2019s health at that time, he said, because it appeared to be struggling and surfacing abnormally. <\/p>\n\n\n\n

It\u2019s not uncommon for killer whale calves to die shortly after birth. Michael Weiss, the research director at the Center for Whale Research, said the first year of life is the biggest hurdle for survival. <\/p>\n\n\n\n

About 70% to 80% of calves that researchers are able to document and give identifying numbers survive their first years. <\/p>\n\n\n\n

\u201cWe don\u2019t know exactly what the survival rate is, because so many calves are probably being born and dying before they\u2019re ever photographed and documented,\u201d Weiss said. \u201cIt\u2019s likely closer to, you know, 50% of calves are born that make it through that first year.\u201d<\/p>\n\n\n\n

NOAA researchers said they are now concerned about Tahlequah\u2019s own health, because pushing the calf creates a lot of drag in the water and requires a lot of energy. <\/p>\n\n\n\n

\u201cOne of the things that she\u2019s probably not having time to do is forage,\u201d Hanson said. \u201cIt is a concern that she\u2019s expending a lot of energy to try to take care of this calf that she has lost.\u201d <\/p>\n\n\n\n

This is the typical calving season for southern resident whales. Hanson said the researchers were encouraged by the birth of the other orca, called J62, which was first spotted by observers on Dec. 30 and confirmed by the Center for Whale Research on New Year\u2019s Day.<\/p>\n\n\n\n

\u201cIt would appear to be very robust,\u201d Hanson said. <\/p>\n\n\n\n

Southern resident killer whales have been a target of conservation efforts for decades. They are protected under the Marine Mammal Protection Act and were listed as critically endangered in 2005.<\/p>\n\n\n\n

The whales typically spend several months each year along Washington\u2019s coastline in Puget Sound. They live in three pods \u2014 called J, K and L \u2014 and have evolved to eat mostly fish, including prized Chinook salmon.<\/p>\n\n\n\n

Beginning in the 1960s, many southern resident killer whales were killed or captured, with some survivors put on display at marine parks. By 1974, surveys found just 71 left in the wild. The population fluctuated after that \u2014 it reached a high of 95 in 1995 but has since been declining.<\/p>\n\n\n\n

The whales are struggling primarily because the quality and quantity of their prey have diminished and because of pollution from industrial chemicals like polychlorinated biphenyls (PCBs), which contaminate their prey and accumulate in their bodies. In addition, noisy vessels can disrupt the whales and hamper communication.<\/p>\n\n\n\n

Research suggests the southern residents are on a path toward extinction unless more aggressive action is taken. Already, Washington state and federal agencies have invested more than $1 billion in programs to reduce the threats to the whales. But the bottom line remains: The southern residents simply don\u2019t have enough food. <\/p>\n\n\n\n

Key streams that once produced ample salmon \u2014 including the lower Snake River \u2014 are dammed, which restricts access to and survival of the fish. <\/p>\n\n\n\n

\u201cWe are not doing enough on Chinook recovery and salmon recovery,\u201d Gaydos said. <\/p>\n\n\n\n

For the struggling southern residents, the loss of a female calf is a devastating blow not only to her mother but also to the trajectory of the entire subspecies. <\/p>\n\n\n\n

\u201cThe real limitation is the number of reproductive-age females and how capable they are of actually successfully rearing the calf. So we definitely want to see more females in the population,\u201d Weiss said. <\/p>\n\n\n\n
