14/12/17: Today I was contacted by a lady researcher in Wales: I was at my home property in Wales tonight about 5 pm when I heard 3 loud unusual calls in the Carmarthen /Brecon Welsh boarder Towns. I was just at home, and there are woodlands at the back of the house, and the calls seemed to be coming from that direction, The house we live in backs onto the woodlands then there are mountains behind that, so there are no buildings or anything in that direction I can think of that the calls could of been. I jumped up but by the time I had made it outside the dogs everywhere in the town were going crazy and drowned out the noise. After a minute everything went quiet so I went back inside. Then about 20 mins later there was one long loud sound again (that I heard) and there may of been more as the dogs went crazy again.
