attack or become threatening. In 2005, Williams was paralysed in an accident, and her claims to the media ceased. She never mounted her planned expedition. By 2006, Hicks and colleagues had completed another long hunt for the chimpanzees during which they were able to observe the creatures a total of twenty hours. Hicks reported, "I see nothing gorilla about them. The females definitely have a chimp's sex swellings, they pant-hoot and tree-drum, and so on". DNA samples recovered from faeces also reaffirmed the classification of these apes in the chimpanzee subspecies P. t. schweinfurthii. When a report on Hicks' research on the New Scientist website was later confused with claims originating from Williams, Hicks wrote to claim the article misreported and misquoted him. In 2019, Hicks and others published a comprehensive on the chimpanzees of the wider 'Bili-Uéré region', as they termed the central part of the Uélé watershed. The old giant ape controversy was ignored entirely. Twenty chimpanzee groups were studied over twelve years. In the work, Hicks et al. classifies the chimpanzees of this area as a behavioural "realm", subdivided into many "regions", united by common preferences and techniques, defined by tool use, dietary preferences and such habits. Chimpanzees of Bili-Uéré, for example, do not eat termites of the Macrotermes genus, which are otherwise much loved by the apes, unless the termites are having a mating swarm. Despite early reports of super-long rods used to fish termites, Hicks et al. document that these chimpanzees do not use rods to fish for termites at all, but instead bash the mounds open against roots. Description Williams initially claimed the apes were bipedal (meaning they walk upright) and stand over six feet (almost two meters) tall, with the looks of a giant chimpanzee; making them look more like the extinct Australopithecine, Sahelanthropus or Toumaï. According to Williams, "They have a very flat face, a wide muzzle and their brow-ridge runs straight across and overhangs. They seem to turn grey very early in life, but instead of turning grey-black like a gorilla, they turn grey all over." They develop uniform grey fur independently of age and sex, which suggests that greying takes place early in life (whereas in all known gorilla species, only males gray as they age and graying is restricted to their backs). A single skull from Bili has the prominent brow ridge and a sagittal crest similar to that
