The Nandi bear is a ferocious, heavily built animal reported from the highlands of western Kenya in the late nineteenth and early twentieth centuries. Witnesses described a beast more than four feet high at the shoulder, with a sloping back, shaggy reddish or brown hair and a terrible reputation: in Nandi tradition, the chemosit was said to attack people at night and eat their brains. No bear is known from modern Africa, and naturalists of the colonial era spent decades arguing over what the animal could be. Most concluded that the “Nandi bear” was not one animal at all, but a composite of several real ones, above all the spotted hyena.[1][2]

Colonial Kenya and the “bear”
The Nandi bear belongs to a particular time and place: the early years of British rule in what is now Kenya, when settlers, officials and railway engineers were moving into the highlands around the Nandi Hills and the Uasin Gishu plateau. Many of them heard the Nandi people’s stories of the chemosit, a nocturnal creature that killed people, and some believed they had seen something strange themselves. Because the most common description was of a large, shaggy, sloping-backed animal, Europeans called it a “bear,” even though no bear has lived in sub-Saharan Africa in recent times.[1][3]
The reports
- 1905, Uasin Gishu. Geoffrey Williams reported seeing a heavily built beast with a long, pointed head, but kept quiet about it for seven years.[3]
- 1905. The soldier and naturalist Richard Meinertzhagen speculated that the animal might be a little-known ape. He also claimed that Nandi informants identified a picture of a chimpanzee as the chemosit.[1][3]
- 1913. N. E. F. Corbett, the district commissioner at Eldoret, said he saw a large animal shamble into the bush beside the Sirigoi River while he was fishing. An engineer on the Magadi railway, G. W. Hickes, described a lion-sized beast with shaggy tawny hair.[3]
- 1913–1914. The administrator and naturalist Charles W. Hobley collected reports, including one of an animal killed at Ngao on the Tana River, and published a drawing of an alleged Nandi bear footprint.[1][3]
- 1925. After a young girl disappeared in the Uasin Gishu district, the colonial officer William Hichens, the same man who described the Agogwe, was sent to investigate and reported losing his hunting dog to the creature.[3]
- 1960. The last widely cited report came from Kipkabus, where a man named Angus McDonald said an animal chased him for several minutes.[3]
What the scientists said
Professional zoologists in Britain took the reports seriously enough to debate them. In 1923 the paleontologist Charles W. Andrews of the Natural History Museum suggested that the Nandi bear might be a surviving chalicothere, an extinct group of large, clawed, horse-related mammals whose fossils are known from Africa. The anthropologist Louis Leakey later revived the idea, although he noted that chalicotheres were plant-eaters, not the killers of the legends.[1]
In 1930, Reginald Innes Pocock, one of the leading authorities on mammals of his day, published “The Story of the Nandi Bear” and argued that most reports were simply spotted hyenas. In 1932 the Natural History Museum stated that many of the reports it had investigated “proved to have been nothing more than a spotted hyena.” Much later, the paleontologist George Gaylord Simpson suggested that many cases were large honey badgers, also known as ratels. In 2000 Louis L. Jacobs argued that a living chalicothere would surely have been found, and that some descriptions may have been garbled accounts of gorillas.[1]
Why the spotted hyena fits
The spotted hyena is the largest of the hyenas, standing up to about 80 to 90 cm at the shoulder, and its powerful forequarters and low hindquarters give it the distinctive sloping back that appears in so many Nandi bear descriptions. Its coat is shaggy and can look reddish-brown, especially on older animals whose spots have faded. Hyenas are mainly nocturnal, have enormously strong jaws that can crush bone, and have been known to attack people, especially sleeping people or children, and to scavenge human remains. A large hyena seen at night, at close range, could easily be described as a bear, and the chemosit’s reputation for eating the head matches the way hyenas feed.[1][5]
Other animals may account for some reports. Honey badgers are small but stocky, aggressive and fearless; baboons can stand upright and are strong and dangerous; and the aardvark, a large, odd-looking, nocturnal burrower, would be startling to anyone unfamiliar with it. Karl Shuker and Bernard Heuvelmans both concluded that the Nandi bear was “almost certainly” a composite created by combining sightings of several different animals.[2]
Fossil candidates
Cryptozoologists have proposed several extinct African animals as possible survivors: the giant short-faced hyena Pachycrocuta, the African bear Agriotherium, the giant baboon Dinopithecus, and chalicotheres. All lived in Africa during the Pleistocene or earlier, but none has a fossil record anywhere near the twentieth century. In 2019 paleontologists described Simbakubwa kutokaafrika, a giant meat-eating mammal known from 22-million-year-old fossils found near Kenya’s Nandi County, possibly as heavy as a polar bear, but it lived far too long ago to have anything to do with colonial-era sightings.[2][4]
Why did the sightings stop?
Reports became rare after the 1930s and seem to have ended around 1960. Shuker suggests that the clearing of the Nandi and Kakamega forests for farming may have driven away whatever animals lay behind the reports. Another explanation is simply that, as colonial settlers became familiar with Kenyan wildlife and the excitement of the early reports faded, there were fewer unexplained encounters to report.[2]
Our assessment
The Nandi bear is a classic case of an unfamiliar landscape, a frightening local tradition and real but poorly known animals combining into a “new” creature. The most likely explanation, supported by the experts who studied the reports at the time, is that it was mostly the spotted hyena, with honey badgers, baboons and other animals filling in the rest. The chemosit itself remains an important figure of Nandi folklore.
