As I walked through the woods at RSPB, I heard the wrens twittering and managed to get a shot of mummy wren but on the way back from the hide, I saw something on a branch but didn't really know what it was. However I'm glad I took the shot as it proved to be 2 baby wrens. I think that is why there was so much twittering.
How sweet Rosie I am always thrilled when I see a wren in my garden -- but have never been able to photograph one as they are so shy and swift in movement !
