They've flown

I saw them go. I took photos of the 5 of them, testing the patience of poor Cholmeley, and had started walking back when I heard them. They flew in formation, low to the water, and the noise was very loud. 
I think they've gone gone.
The 2 parent swans have not shown any interest in them for weeks.
So I've put a few extra photos in. It feels a little sad.
