Taken today in New Forest, the white one very pretty indeed.
The Goosander I have seen before do not seem to have this variety in colour, so maybe these are another species of diving ducks?
Slightly out of focus, but my camera is finally packing up on me, the AF no longer works... :O(
ATB.
Sorry Rich, these are not Goosanders. They all appear to be Mallard variants which are sometimes known as Manky Mallards. Basically, Mallards which have been selectively bred often for domestic purposes. You can check out the weird and wonderful variations HERE.

Hi Rich totally agree with the others, definitely Mallards (Manky variety). This is a shot I took the other week of some Gossanders, sorry not the best of pictures but they were along way a way and testing for my 135mm lens. As PB mentioned you can see the hook on the end of the beak.
