In a poignant reminder of the struggles faced by endangered Pacific Northwest orcas, Tahlequah, also known as J35, has been observed carrying her deceased calf once again. This behavior, noted by researchers, marks a recurrence of her actions in 2018 when she gained worldwide attention for carrying her dead calf for an extended period. This incident underscores the ongoing challenges and emotional bonds within orca populations.
In 2018, the world was captivated by the sight of Tahlequah carrying her deceased calf for 17 days, covering more than 1,000 miles. The mother orca, part of the southern resident killer whale population, demonstrated profound grief by keeping her calf afloat, supported by her pod. This display of mourning reflects similarities to behaviors observed in other socially complex animals like primates and dolphins.
Recently, the Center for Whale Research confirmed that Tahlequah is again carrying a dead calf, a female that lived only a few days. Researchers, including Brad Hanson from NOAA, witnessed Tahlequah balancing the calf on her snout or head and diving after it when it sank. Joe Gaydos of SeaDoc Society interprets this as a manifestation of grief, a behavior not uncommon among orcas but rarely witnessed to this extreme.
The tragic loss of another calf is significant given the critical status of the southern resident orca population, which numbers just 73 individuals. These orcas face numerous threats, including a scarcity of Chinook salmon, pollution, and vessel noise, all of which threaten their survival. Calf mortality is notably high, with only about 1 in 5 pregnancies surviving the first year, according to Michael Weiss from the Center for Whale Research.
Despite this grim scenario, there is a glimmer of hope. Another new calf, J62, has been observed alive by scientists, offering a potential boost to the dwindling population. The importance of each birth cannot be overstated, as each whale plays a crucial role in the survival and potential recovery of the species.
The southern resident killer whales are distinctive, primarily because of their diet of salmon rather than marine mammals. Identified by unique physical markings, these orcas are known to travel in family groups, often seen in the Puget Sound area. Their continued survival hangs in the balance, as they confront ongoing environmental challenges.
Tahlequah’s behavior highlights the profound emotional connections and the plight of endangered orcas. Efforts to support and protect these magnificent creatures must continue to prevent their extinction. Each loss is a stark reminder of the urgent need for conservation measures.
