I was wondering if anyone could help with this. Today we were exploring in some woods and we heard a very strange animal noise. It sounded a bit like a door that needed some grease putting on the hinges. It occured regularly, sometimes every couple of minutes, sometimes five or ten minutes apart. Despite being very close to whatever was making the sound we didn't see a thing, it was very well camouflaged. This wasn't anywhere near the Deer I saw yesterday by the side of the road. That was a tiny area near a busy junction. This today was amongst thick woodland. At the time I thought it could have been a young animal calling for the parents but I'm sure I would have spotted something. It's left me feeling very puzzled.
