In a remarkable incident witnessed at the Serengeti National Park in Tanzania, researchers have discovered a lioness that has seemingly adopted a newborn leopard.
This extraordinary event echoes a similar occurrence at India’s Gir National Park, where a lioness nursed a young male cub, caring for it alongside her own offspring.
The act of inter-species fostering, described as “bizarre” in the journal Ecosphere, has puzzled researchers. From an evolutionary standpoint, it seems illogical for an animal to invest time, energy, and resources into caring for the offspring of another species.
Typically, the primary goal of parenting and providing for young ones is to ensure the propagation of one’s own genes.
While instances of animals raising non-biological progeny do occur, such actions are usually undertaken to enhance the reproductive success of the caregiver, as highlighted by the study’s authors.
For instance, female cheetahs often adopt orphaned male cubs, establishing wide-ranging alliances with their mothers’ progeny when they reach adulthood.
While inter-species adoptions are rare, instances of cross-species fostering between competing animals are exceptionally uncommon.
In this particular case, a lioness named Nosikitok stumbled upon a solitary leopard cub near her own den.
Strikingly, the cub was approximately the same age as her own cubs, which had not been seen for a considerable period.
In the wild, lions are known to prey on each other’s cubs, and encounters between adults and tiger cubs from different feline species often end in fatal outcomes. Thus, this inter-species adoption is an exceedingly rare occurrence.
The lioness has taken the orphaned cub under her wing, providing it with protection akin to that offered to her biological offspring.
While it remains uncertain if the lioness has fully adopted the newborn leopard, it is heartening to witness her care and commitment to the cub’s well-being until it reaches maturity.
Dr. Sarah Durant from the Zoological Society of London speculates that the lioness likely encountered the leopard cub before her parental hormones ceased their effect.
However, it is unknown how Nosikitok’s pride will react to the presence of the newcomer, making the ideal outcome the cub’s eventual reunion with its biological mother.
Dr. Luke Hunter, president and director of conservation, describes this unique occurrence as fascinating and eagerly anticipates the results that will unfold from this extraordinary interspecies interaction.
