Compositionally, the second shot really works for me. There is equivalence between the bird and the open area he landed on – the black shoulder spot is matched by the dark water of the open area, and the grey of his/her body corresponds to the grey opening of ice in the snow. I’m thinking you did some post-processing to blur out the horizon as the reflections in the water seem to imply some detailed background, which I can’t see.
I’m thinking that the bird is getting hungry with the cold snap that you are experiencing – how does it look for its usual food when everything is frozen over?
