How many frogs?
I don't usually get frogs in my garden, but whenever I've gone out in the evening or night over the last few months, there's a frog. It's usually in one corner of the garden, though occasionally I see it in another spot. If I disturb things in the corner where I assume it lives, I can hear it jump around. I've never seen or heard more than one frog.
So, is this likely to be the same frog or am I only just spotting one at a time? I'm sure it's the same one because it's always the same size and usually lurking in the same corner of the garden, but I would have expected garden frogs to live in groups.
