a man who threw rocks at them led them to throw back fistfuls of grass. All the encounters had the gorillas in the group observe the researchers and react to their presence with vocalizations then led to calm behavior in the parts of the gorillas and finally an approach by the male gorillas and the throwing of grass at the researcher. The researchers have stated that this throwing behavior might have arisen due to human contact in the field and farms surrounding the mountain and the ambivalent nature of the gorillas is due to the surrounding people not hunting the gorillas due to the folklore about the gorillas. Geographical distribution This subspecies is populated at the border between Nigeria and Cameroon, in both tropical and subtropical moist broadleaf forests which are also home to the Nigeria-Cameroon chimpanzee, another subspecies of great ape. The Cross River gorilla is the most western and northern form of gorilla, and is restricted to the forested hills and mountains of the Cameroon-Nigeria border region at the headwaters of the Cross River. It is separated by about from the nearest population of western lowland gorilla (Gorilla gorilla gorilla), and by around from the gorilla population in the Ebo Forest of Cameroon. Groups of these gorillas concentrate their activities in 11 localities across a range, though recent field surveys confirmed the presence of gorillas outside of their known localities suggesting a wider distribution within this range. This distribution is corroborated by genetic research, which has found evidence that many Cross River gorilla localities continue to maintain contact through the occasional dispersal of individuals. The occurrence of Cross River gorillas has been confirmed in the Mbe Mountains and the Forest Reserves of Afi River, Boshi Extension, and Okwanggo of Nigeria’s Cross River State, and in the Takamanda and Mone River Forest Reserves, and the Mbulu Forest, of the Cameroon’s South West Province. These locations cover a mostly continuous forest area of about from Afi Mountain to Kagwene Mountain according to the 2007 regional action plan for Cross River gorilla conservation. Researchers and conservationists also postulate that there is a possible outlying locality in the forests near Bechati in the southeast. Today it’s estimated that their total population area covers about . Cross River gorillas have been known to cling to the Afi-to-Kagwene landscape because of its rugged terrain and high altitude which keeps it secluded from human interference.
