Ducklings again

I went back to Blackford Pond this afternoon to check if the cygnets had hatched, and it looked as if they hadn't - Mrs Swan was on the nest and Mr Swan was at the end of the pond again. I saw these two ducklings in a different part of the pond than last time, so I don't know if it's the same family who have lost one or a different family. Sadly I tripped on a tree root while I was watching a little grebe and damaged my new camera. I also damaged myself but I will heal up and my camera won't!
