This was our first ever garden weasel - I was alerted to its presence by the most awful (ie something being killed) noise down by the shed. I investigated and saw some movement, then a weasel popped up on top of a pile of paving slabs, looked at me for a few seconds, then disappeared. I waited to see if it would re-appear and amazingly it did - back up on to the paving slabs, only about 4 feet away, and it looked straight through me at something very interesting behind me. I kept quite still and it jumped down off the slabs, ran straight between my legs and under some big sheets of blue plastic behind me. What a sighting - brilliant! No camera to hand, of course.
Perhaps the presence of weasels explains why our rat population seems to have diminished and rabbits never seem to get a foothold?
