Swan family on the moat

The cygnet has survived! First time in three years I think - previously all the babies have disappeared - this year there were four to start with - one disappeared quickly (there are Pike in the moat) - two suddenly died a couple of weeks later - but this one has grown up and is now able to do a 'bottom up' (see extra). Notice how clear the water is - see other extra for close up of the parent swans and see how clear their necks and heads appear under the water.
