Areas like the one Martin has posted tend to be favoured by muntjac, scrub land with blackthorn and thick hedges with good rough ground. We always found them to use the hedges as go betweens, we used to stalk one piece of ground and you would guarantee to see one up each hedgerow, and this was on headlands of large arable fields, some up to 100 acres in size.
Quite often see them in the middle of fields, but not huge fields, the biggest one being maybe 40 acres in size, just grass fields after being cut for hay/silage. Normally in these circumstances though the density of animals is quite high, could take you to a field now where there are 3 young bucks coming out each evening into the middle to feed.
What time do you want me there? Thanks for all the replies folks, keep em coming, very interesting
