"M. muntjac" is a terrestrial mammal. A close survey of its microhabitat on Hainan Island was conducted from 2001 to 2002 by tracking with radio collar the localities of three females and two males. Results showed a favoritism towards shrub grassland, thorny shrub land, and dry savanna over woods, cultivated grass plots, and deciduous monsoon forests. Food availability was higher at foraging sites than at bed sites, but bed sites had taller and denser vegetation. No significant difference in wet vs dry was found in food abundance, so habitat selection seemed to be based upon maximum tree height and canopy diameters.
