On the southern side of the dam, I first saw a single European Red Fox at the base of a large tree. I thought the fox saw me and fled to the south. I then realised it had not gone far. Very soon afterwards, up to three more foxes from the east headed towards where I presumed the first fox had gone. I heard the noise of what sounded like wood hitting wood, although I could not see anything. A short time later I saw three or four foxes heading towards the north-west at a trot before I lost sight of them in the undergrowth. When I went to the area where I thought the wood hitting wood sound had occurred I saw a large, old, fallen tree with broken branches surrounding it. The tree had been lying there for a very long time, probably years. I could not see any signs of activity there so I am not sure what the wooden sound was.
