In an extraordinary display of maternal instinct, scientists in Canada have recently observed a female polar bear engaging in the rare behavior of adopting another cub. This fascinating occurrence not only sheds light on the intricate social dynamics of these apex Arctic predators but also emphasizes the deep nurturing qualities inherent in polar bear mothers.
Polar Bears International, a dedicated non-profit organization focused on polar bear conservation, reported on Wednesday the remarkable findings stemming from their research. Initially, when researchers fitted a GPS collar on a female polar bear during the spring season, she was seen caring for one young cub. However, a month later, observers were surprised to see her with two cubs that appeared to be nearly the same age, leading them to conclude that they had just witnessed a rare instance of adoption.
Evan Richardson, a research scientist with Environment and Climate Change Canada, remarked, "Female polar bears are really excellent mothers, and they are naturally inclined to nurture their offspring. If they encounter a little cub that is crying on the coast, having lost its mother, these females often feel compelled to adopt and care for it. This behavior is quite intriguing and highlights a unique facet of polar bear life."
The mother, identified by scientists as bear X33991, belongs to the Western Hudson Bay polar bear subpopulation, which is one of the most extensively studied groups globally. Researchers have been documenting their feeding habits and movements for nearly fifty years. Out of approximately 4,600 polar bears examined throughout this period, this adoption marks only the thirteenth instance recorded in this population.
Alysa McCall from Polar Bears International expressed her awe at this phenomenon, stating, "Polar bear adoptions are exceedingly rare and strikingly unusual, and we still don’t fully understand why they occur." Witnessing such a sight is indeed considered "amazing."
The two adopted cubs, estimated to be around ten to eleven months old, appear to be thriving and well-fed. They are expected to remain with their adoptive mother for an additional year and a half, during which time they will learn vital survival skills. Recent GPS tracking data indicates that the trio has already ventured onto the sea ice, where the cubs will depend on their mother for hunting seals. They will not only share the food she catches but will also be taught how to hunt for themselves in this harsh yet sometimes plentiful environment.
Life on the ice presents significant challenges, as polar bears endure long winters hunting for food and face several months of fasting during summer. Alarmingly, statistics show that about fifty percent of all born cubs do not survive to adulthood. Nonetheless, experts believe that being cared for by a mother significantly enhances the chances of survival for the adopted cub. Historically, among the thirteen documented adoption cases over the past forty-five years, only three cubs have made it to maturity.
Researchers are set to analyze genetic samples from the newly adopted cub to ascertain whether the mother is already known to them and whether she might still be alive. In some previous adoption instances, the biological mothers were found to be alive, suggesting a possible “switching of litters” rather than a scenario where the cub was left orphaned.
McCall reflected on the emotional complexity surrounding this adoption, stating, "We may never know what happened to the biological mother of this cub. Upon confirming the adoption, I felt a mix of emotions. But this situation serves as another reminder of the incredible nature of this species and their intriguing behaviors. It fills you with hope to realize that polar bears may indeed look out for one another."
