James,

In the last image the Coyote was watching it's mate who was out on the ice. The mate was much more concerned by my presence and did not want to come in close.

One other note, the first two images were of a lone coyote while the last image is one of a pair. The pair seemed to have wintered better than the loan coyote as their coats where much better and they seemed to be a good bit "fatter".
