This eyeshine was captured during a night-time investigation of Cuthbright Wood, Sherwood Forest, Nottinghamshire, by British Bigfoot Research founders Adam and Paul Bird. A couple of interesting things were heard during the investigation. First of all, a possible single wood knock was heard, and this was before Adam and Paul did any knocking themselves, so whether this was a warning, nobody can say. After that it was silent for an hour. It was then that they heard what can only described as a chattering sound, like someone muttering under their breath. The source of the chattering sound was never found.
Nothing was seen at the time but one of the photographs showed what looks to be eyeshine (See pictures in comments below)
