The black headed gulls are all down at the sluice with their fledged young getting to know the joys of bobbing up and down in the water. All except these two who seem to have decided that water is not for them. Dad tried to encourage them and in the ensuing squabble one of the twins fell in. It wasn't staying wet for long and soon managed to get back up. In the end dad gives up in disgust. They may well still be there tomorrow.
