Crab-eating macaque durians such as "Durio graveolens" and "D. zibethinus", and are a major seed disperor for the latter species. Although the species is ecologically well-adapted and poses no threat to population stability of prey species in its native range, in areas where the crab-eating macaque is not native, it can pose a substantial threat to biodiversity. Some believe the crab-eating macaque is responsible for the extinction of forest birds by threatening critical breeding areas as well as eating the eggs and chicks of endangered forest birds. The crab-eating macaque can become a synanthrope, living off human resources. They are known to
