Miller's Grizzled Langur (Presbytis hosei canicrus) is part of the small primate genus Presbytis, found across Borneo, Sumatra, Java and the Thai-Malay Peninsula. In Borneo, P.h. canicrus is only found in a small corner of the county's north east and its habitat has suffered from fires, human encroachment and conversion of land for agriculture and mining.
The team's expedition took to them to Wehea Forest in East Kalimantan, Borneo, a large 38,000 ha area of mostly undisturbed rainforest. Wehea contains at least nine known species of non-human primate, including the Bornean orangutan and gibbon.
