One of my previously held theories for successful Muntjac calling was that it needs a decent strength of wind so that the trees etc. movement and noise will help to disguise my attempts at deception. However this morning I was out at first light to a very soggy fenland wood. After a good two hours of seeing no deer, I thought that I would try calling. So I positioned myself looking into dense cover at about sixty yards distance with less dense cover closer to me. There was not a breath of breeze.
After the second set of calls, a Muntjac buck appeared from the dense cover into the less dense bit, clearly coming to investigate the call. I was able to get a shot in and bagged him. I had my Labrador bitch 'Ruby' with me and we had to walk around a water filled ditch for several hundred yards to recover the carcass. I am very pleased to say that Ruby found him for me in no time at all and saved me much searching.
So a good result, but this particular Muntjac (15.5 kgs whole, with a full set of teeth) was called in still-air conditions. I think that was my last theory on calling Muntjac, so still none the wiser.
