I spotted the white duck last year when I was in Helsinki in winter. I am pleased to say that the duck is still in the water at Toolonlahti and doing well and fitting in with the others.
People leave food for the ducks to get them through the winter.
I saw a duck friend on my walk around Toolonlahti. The ducks ran to meet her and were happy with her offerings.
It seems a few ducks have learned that it OK to stay behind for the winter.
