. The British Deer Society coordinated a survey of wild deer in the UK between 2005 and 2007, and they reported that Muntjac deer had noticeably expanded their range since the previous census in 2000. It is anticipated that Muntjac may soon become the most numerous species of deer in England and may have also crossed the border into Scotland with a couple of specimens appearing in Northern Ireland in 2009; they have been spotted in the republic of Ireland in 2010, almost certainly having reached there with some human assistance.

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 Chinese Water Deer also have visible tusks (downward-pointing canine teeth); however, they are much less widespread.
