Thanks for that. I Googled the bat group and it does look intersting. I watched the BBC programme with Iolo going into the caves to look for bats the other day, oh boy did the claustrophobia kick in, but they were beautiful when he eventually got there. I'm glad I can sit at then of my garden with a glass of wine and enjoy them.
I'm not sure what size they were, I'll check that out next time.
