If you pop down to Cosmeston Lakes Visitor Centre you will see a large screen showing the beginnings of new life in a nearby nestbox. A female blue tit busies herself with the task of lining the nest.
'This is great' I hear you say, 'but what has this got to do with the exploits of the Cardiff Ringers?'..
Well..she's got a ring on her leg, and it was me who put it there. Is that enough?
(The truth is that I dont get out much these days)
