UFOs are here ! K-18

Just found my old camera and a memory card in it. Of course, I checked whether there would be some pictures. Yes - there were a couple of real interesting pictures.
Last summer I was checking sparrow nests on a roof of neighbour house. I felt that someone is watching me. When turning around I saw somekind of flying object nearby. Fortunately I had my old camera with. There was not much time, but I could take one picture.
It would be nice to know what those tree humanoids were doing here. Maybe they were just interested in my lightning radar or other antennasystems.
