A devasted orca mother carries her dead calf with her for almost three weeks – showing how maternal bonds exist across species. Orcas, often known as killer whales, are not just magnificent in their physical prowess. They are also profound in their emotional capacity. This story of an orca mother, Tahlequah, serves as a testament to the depths of orca emotions and maternal bonds.
From the mourning journey of a bereaved orca mother to the eventual happy ending, the birth of a new calf, this story is one of resilience and survival. This article provides an overview of Tahlequah’s journey, but we will also delve into the critical conservation status of the Southern Resident Killer Whales.
Orca Mother Carries Dead Calf: Her Emotional Journey
In 2018, an orca named Tahlequah, or J35, from the Southern Resident Killer Whale population, made headlines worldwide when she displayed an unusual display of grief. She gave birth to a calf that tragically died just half an hour after birth. Then, Tahlequah embarked on what scientists refer to as a “tour of grief”. The mourning orca mother was spotted carrying her dead calf for 17 days across 1,000 miles. Such extended period of grief had rarely been seen in orcas. As a result, it captured the attention of researchers and the public alike.
Tour of Grief and Sorrow
Tahlequah would balance the calf on her forehead, occasionally diving to retrieve it whenever it slipped off. This remarkable demonstration of sorrow and maternal bond continued unabated until the day the orca finally let go of her deceased offspring, a poignant symbol of her heartbreaking loss. Her mourning journey stretched across the vast expanses of the Pacific Northwest. It started near Victoria, British Columbia, where the calf was born. 1000 miles later, she let go of her calf somewhere in the Salish Sea.
What this Indicates about Orca’s Emotional Intelligence
The profound grief expressed by Tahlequah in response to her calf’s death underscores the deep emotional bonds and intelligence prevalent in orcas. Many marine biologists consider these reactions as indicative of high emotional intelligence, even comparable to those of humans. In orca societies, mother-offspring bonds are exceptionally strong and long-lasting, often persisting throughout the animals’ lives. The loss of a calf, especially given the low birth rate in this species, can thus evoke a profound grief response.
The heartbroken orca mother carried her dead calf for almost three weeks. This intensity and duration of Tahlequah’s mourning also underscore orcas’ capacity for long-term memory and emotional depth. It suggests that orcas are capable of experiencing a range of emotions. It likewise illustrates that they have a considerable capacity for empathy and compassion.
Conservation Status of Tahlequah’s Pod
Tahlequah is a member of the J pod, one of three pods (J, K, and L) that comprise the Southern Resident Killer Whales (SRKW) population. The SRKW population is critically endangered, 74 individuals remain according to the last count in July 2023. This includes about 23 orcas in the J pod, of which Tahlequah is a member. It also includes additional members in the K and L pods. This population decline from historic numbers, which were believed to have been around 200, illustrates the dire predicament of these creatures.
An Involuntary Diet: Orcas are Getting Skinnier and Skinnier
The SRKW population faces a severe food crisis. Their primary food source, the Chinook salmon, is in decline. This is due to factors such as overfishing, habitat destruction, and climate change. As these salmon comprise up to 80% of the SRKW diet, their scarcity is leading to nutritional stress among the orcas. This, in turn, is leading to their diminished health and reproductive capabilities – which might be the reason why Tahlequah’s calf passed away. This situation is intensified by the orcas’ specific preference for Chinook salmon due to its high fat content and year-round availability, making their survival closely tied to the fate of the Chinook salmon population.
High Fatality of Newborns
Beyond the food shortage, orca calves face additional challenges from pollutants and noise pollution. The orcas’ fat tissues store toxic substances, including PCBs, that are accumulated from their diet over their lifetimes. During gestation and lactation, these toxins are transferred from the mother to the calf. This toxin transfer weakens the calves’ immune systems and makes them more susceptible to diseases, leading to a high mortality rate among newborns.
A Happy Ending: Tahlequah Gives Birth Again
In September 2020, the sighting of Tahlequah, or J35, with her new calf, J57, brought worldwide joy and relief, symbolizing hope for the endangered Southern Resident Killer Whale population facing potential extinction. Believed to have been born on September 4, 2020, J57 was observed swimming energetically beside his mother, with visible fetal folds indicating a recent birth. This event not only marked a significant addition to the population but also highlighted the importance of ongoing conservation efforts aimed at supporting the recovery of these remarkable whales and their habitat.
Orca Mother Carries Dead Calf: Conclusion
The saga of Tahlequah highlights the existential struggles of the entire Southern Resident Killer Whale population, embodying themes of grief and loss while showcasing their deep emotional intelligence, akin to that of humans. Amid this sorrow, the birth of J57 symbolizes a hopeful step toward the recovery of this endangered species. Tahlequah’s journey underscores the vital connection between orcas and their environment, stressing the urgent need for conservation efforts. As we celebrate J57’s arrival, we are reminded of our shared responsibility to protect the habitats and food sources crucial for the survival of these remarkable whales, necessitating immediate and significant action.
