A couple of days ago I was waiting for voles and a stoat appeared, slinking through the grass. It's been a week and a half since I had a good photo of a water vole, and it struck me that perhaps they'd changed their patterns to be more nocturnal and avoid the predator. There were still plenty of field signs about. I stuck the trail cam down and yes, it looks as if that's the case.
Which leads me to another question: when do water shrews ever sleep?
