Thanks Jason,Janet,Gordon and Dawn. What is it about me? Even if I genuinely post a SERIOUS wildlife question,the thread ends up as a comedy show, this time without any help AT ALL from me, but I bet I'll get the BLAME HeyHo, maybe I should change my username to 'BroadShoulders.', 'cos I'm gonna need them, I can see it coming.
****** Actually on rereading thread from the start I can see that it had already evolved into a comedy, before I appeared so SORRY everyone for taking 'credit' that wasn't mine. I'm obviously getting too sensitive ! !
