This is a diurnal and arboreal species (Saiful and Nordin 2004), descending only occasionally to ground to forage (Han pers. comm.). This species can tolerate secondary forest, and often enters fruit orchards (Han pers. comm.). 

This species is found in the dense rainforests of the southern Thai peninsula, eating mostly fruit, but also some arthropods, and is considered a pest of oil palm and coconut plantations (Lekagul and McNeely 1988, Meijaard and Sheil 2007).

This species is widespread in the southern part of Thailand, throughout Malaysia, Sumatra and Borneo, and on many smaller islands of Southeast Asia and Peninsular Malaysia (Corbett and Hill 1992, Oshida et al. 2001). It also has been found in northern Sulawesi where it has been introduced (Musser 1987).

It occurs in many protected areas. Saiful and Nordin (2004) state the need for further comparative study on this species' abundance, density and distribution and its relationship to forest structure or habitat quality, spatially and temporally, in hill dipterocarp forest of Malaysia.
