Upland squirrel

The upland squirrel (Sundasciurus tahan), also called the mountain slender squirrel, is a rodent in the family Sciuridae. It is native to Peninsular Malaysia and lives in montane and lower montane forests, including parts of the Titiwangsa Mountains and Gunung Tahan, the mountain that gives the species its scientific epithet. Published handbook notes recorded by the Global Biodiversity Information Facility give a head and body length of about 155 millimetres and a tail of about 104 millimetres, with a speckled brownish back marked by white-tipped guard hairs, a grey belly and a ringed tail. It resembles the slender squirrel, Sundasciurus tenuis, but is darker and larger. It is presumed to be active by day, although no specific information on its behaviour is available. It has not yet been assessed as a distinct species on the IUCN Red List.
