Muntjac seasonal rut, and mating can take place at any time of year; this behaviour is retained by populations introduced to temperate countries. Males have short antlers, which can regrow, but they tend to fight for territory with their "tusks" (downward-pointing canine teeth). The presence of these "tusks" is otherwise unknown in native British wild deer and can be discriminatory when trying to differentiate a muntjac from an immature native deer, although water deer also have visible tusks; however, they are much less widespread. Muntjac are of great interest in evolutionary studies because of their dramatic chromosome variations and the recent
Indian muntjac the microhabitat of Indian Muntjac in Hainan Island was conducted from 2001 to 2002 by tracking via 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 plot and deciduous monsoon forests. Food availability was higher at foraging sites than at bed sites but bed sites had taller and denser vegetation. There was not a significant difference in wet vs dry was found in food abundance so habitat selection seemed to be based upon maximum tree high and canopy diameters. "Ornithodoros indica" has
