I was a little worried last night because I saw not a sign of any hedgehog activity, and was wondering what must have happened to them. However, I left the infrared motion-detector camera out and sure enough there were lots of comings and goings later on. This would have been in the early hours of Saturday morning.
I have to confess that I'm a little jealous of those who have early evening hedgehog visitors. I'd love to be able to watch them in better light. Unfortunately "my" hogs seem to be getting later and later as the weeks go by.
