This little duck was on my local little lake that i visit most days, and i have'nt seen him there before, he was diving and staying under quite a time feeding, and one time reappeared with this acorn!
I have no idea what it is, in my book (me and my book!) the closest it resembles is the tufted duck, but i didnt see any tuft on this little one.
Paulnj you might be able to help me here?
