You might just see the dusty coloured cygnets cruising close by their hardworking parent.
When I walked back again the babies had got back into the nearer nest - work finished for the day, obviously.
Sadly I'm not a good enough photographer to actually show you the island birds, busy carrying twigs and branchlets from the newly fallen trees, over to their island - I guess for their nests.
Some nests needed no repair work.
And some were so relaxed by the first warm sun for a week or so that they just hung around the paths and couldn't be bothered moving for anyone.
I love the way swans are able to fold themselves into intricate knots when they take a nap.
But why do they find it relaxing to rest on one leg? All around the lake stood one-legged swans, basking in the sun.
