Three moods of the Cattle Egret in early spring: Grumpy, Eeek!, and Hungry.
A lone Cattle Egret, by all appearances not terribly amused at the notion of unusually late springtime sleet and snow. This specimen exhibits the yellow / orange highlights of breeding plumage - so it's possible that the apparent surly attitude is a case of "all dressed up, and no place to go."
Or maybe it's about as thrilled at the idea of one last outburst of winter on the first weekend of May as the rest of us...
