Yesterday (21 July) I spotted Eddy the swan (who lost her partner Prince in May this year) leading her 5 cygnets up the canal. It was almost mid-morning and sunny. The cygnets, who are still very young and fluffy, wanted to keep their heads under their wings when I saw them later closer by, but she was encouraging them to imitate her in drinking canal water and presumably feeding on whatever they find in there!
