It's still pitch black when I get up in the mornings, so I have to rely on Billy to let me know if any creatures are around outside.
Yesterday morning he let out a couple of very quiet barks, so I went back indoors and fetched both my torch, and my camera.
This was the first fully grown Hedgehog I've seen for years. He (or she) was rolled into a ball, and didn't move. I expect Billy frightened him. I don't suppose he liked my camera flash either.
I consider it a sign that Mother Nature is doing a good job, when I see Hedgehogs; all is well in the countryside.
