Hedgehogs can also change behaviours. When one of the females had young hoglets in the nest, she was very bold, wandering around in the daytime, didn’t mind people etc. I think she was just so focused on food and water she was oblivious to everything else. Once the young were raised and had gone their own way, she came back occasionally on visits, but was much shyer and more nervous.
That said, I have though ‘oh that might be such and such because she’s behaving in that way’. It’s probably not terribly accurate but I wouldn’t have a clue otherwise, there’s not enough light to see the specific markings as Nic describes, and I’ve noticed that very often I can’t even reliably judge the size of the hog in the low light.
