Liquid Duck

This is one of those shots which I think you can never be sure of.
The Mallard was ducking and diving in celebration of a good meal I think?
I had gone to the Moat to feed them after a meeting with the Community Manager at our Local Asda store.Where it was agreed that they would provide suitable foodstuffs from their waste,throughout the severe Winter period!
Of course it means that I have volunteered myself to get to the store every other day and then go feed the Ducks! That should be a challenge in a foot of Snow or more? lol
Back to the photo! I took a series of shots,but this one stood out in that it is almost as though it is in a bubble?
The water has ''frozen ''in time so to speak! Quite a surreal effect I think?
Stopped the action quite well at 1/125 @ f7.1.ISO was 900,on what was another Grey day. With the Nikon D800 + Big Sig!
