Hello again, I wrote to you on the 31st of March about a Mute Swan Cygnet being aggressive to it's mother. Well the Cygnet is still here, we have a new brood of four cygnets and the last year's Cygnet is part of this family chasing off ducks etc and gaurding the new brood just like the parents. Strange ? Last year's Cygnet is the farthest away swan. Henry.
