Dusky Leaf Monkey (Trachypithecus obscurus)

The dusky leaf-monkey lives in the countries of Burma, Malaysia and Thailand (Curtin, 1976, 1980; MacKinnon and MacKinnon, 1978; McClure, 1964; Aggimarangsee, 2002; Anonymous, 1993/1994). This species may also occur in the Gaoligongshan Region of Yunnan, China (Ma et al., 1995). This species prefers to live in closed primary forests, but is also found in old-growth secondary forests and urban forests (MacKinnon and MacKinnon, 1978, 1980; Curtin, 1980; Southwick and Cadigan, 1972). The dusky leaf-monkey spends most of its time in the upper canopy levels of the forest (MacKinnon and MacKinnon, 1978, 1980; Fleagle, 1978).

The dusky leaf-monkey is a folivorous species, but it will also consume fruit and flowers. Young leaves constitute a high proportion (52%) of the diet for this species (Aldrich-Blake, 1978). Fruit consumed tends to be unripe (MacKinnon and MacKinnon, 1980). Dusky leaf-monkeys are able to take advantage of unripe fruit, which have chemical defenses, by the same means that they breakdown toxins in plant leaves, the bacteria found in their digestive system (MacKinnon and MacKinnon, 1980).
