I had seen this kind of deer a couple of times in Acres Wild but was not ready with a camera. the first time I mistook it for one of our goats. After getting it on camera I did a bit of research and realised that it is a barking deer, also known as Kakad or Muntjac.
Now I remember the instance when a family that works with us was staying here at the farm at night. They got scared by this barking sound and thought that it was some pranksters trying to scare them. It all makes sense now.
