Fulvous whistling duck (Dendrocygna bicolor) at St James's Park, England

I spotted this nice tropical duck in the St James's Park somewhere around Christmas. It is called Fulvous whistling duck (Dendrocygna bicolor) and is normally seen in Africa, South America or India and I guess it felt a bit cold in the chilly England winter.

To make sure it is not its cousin the Lesser whistling duck take note of the black strip on the back of its neck and the light creamy feather above the tail (the Lesser one has them in reddish chestnut colour)
