Judging by the infant’s size and the last recorded sighting of UP, the team estimated that the albino newborn was about 2- to 2-and-a-half weeks old. At the time of the young chimp’s birth in summer 2018, the chimp community consisted of about 75 individuals.Ī 19-year-old female chimp, which the researchers referred to as “UP,” was known to be pregnant in January 2018, and on July 15 of that same year, she was seen carrying a “white” infant, later confirmed to be a male. The albino chimp was spotted among a population of eastern chimpanzees (Pan troglodytes schweinfurthii) in Uganda’s Budongo Central Forest Reserve. Now, the new study provides a unique glimpse into the brief life of an albino ape in the wild. Because Pinkie was collected from the wild at just a few weeks old, scientists didn’t have the opportunity to observe her interactions with wild chimps. The only albino chimp ever reported was a western chimpanzee (Pan troglodytes verus) named Pinkie, who was found as an infant and sheltered in the Tacugama Chimpanzee Sanctuary in Sierra Leone until her unexpected death at age 9. These included a few toque macaques (Macaca sinica), bonnet macaques (Macaca radiata) and spider monkeys (Ateles geoffroyi), and among the great apes, an albino western lowland gorilla (Gorilla gorilla gorilla) was once captured in the wild as an infant and then kept in captivity until its death in adulthood. ![]() In conclusion, this observation represents an extremely rare opportunity to investigate chimpanzees behaviour under equally extremely rare social circumstances.The scientists noted that only a handful of nonhuman primates with albinism have been spotted in the wild in the past. Caroline Asiimwe & John Walter Akankwasa, the vet and vet assistant in BCFS, confirmed no other apparent health condition affected the infant. We could also confirm that these differences were solely due to the coloration of the baby chimp, as an autopsy performed by Dr. This, in addition to the initial fearful reaction, led us to believe that the chimpanzees perceived this infant as one of them, but with unusual appearance. Indeed, while some of the behaviours displayed corresponded to the behaviour usually displayed towards dead infants, chimpanzees spent a considerable time inspecting the body, touching the white hair of the infant and smelling the carcass, probably trying to get more information about this chimpanzee. It is the reaction towards the corpse of the infant with albinism from other chimpanzees in the community that was, to some extent, different from the reaction they would usually have. However, it is important to note that infanticides in the Sonso community are regularly observed, and this baby could have been a victim of infanticide despite its appearance. Indeed, the chimpanzees later came out of the dense thickets and had killed the baby chimpanzee with albinism. The mother fled with her baby to avoid aggression and was not seen after that this day.įour days later on the 19th of July, Bosco Chandia and Maël Leroux, another Field Assistant and a Researcher working at BCFS, heard screams coming from thick vegetations, indicating an aggression was taking place between chimpanzees. Most made alarm calls and waa-barks when seeing the infant for the first time, both vocalizations are known to be produced in dangerous situations such as when encountering a snake. They observed several adult individuals interacting with the baby and its mother. The baby chimpanzee with albinism was first spotted on 15 July by Monday Gideon and Pawel Fedurek, a Field Assistant and a Researcher working at Budongo Conservation Field Station (BCFS). While other cases of chimpanzees with albinism might have occured in the wild, it was not documented, and our observation hence represents an unprecedented opportunity to describe how chimpanzees react to the presence of another chimpanzee with an unusual appearance. Before this observation, only one other chimpanzee has been seen with a similar condition: Pinkie, held in captivity upon first sighting and until she died. Individuals with albinism are extremely rare in animals: even in humans, only 1 out of 17,000-20,000 person has albinism. The baby chimpanzee was born a couple of weeks before observation, his hair completely white and his eyes pink. Albino infant chimpanzee sighted in Sonsoįor the first time, a chimpanzee with albinism was observed within the Sonso community, in the Budongo Forest Reserve.
