This little Snowy was fishing in a shallow fast-flowing stream, and it caught a nice one too as I watched, but in a spot I could not get a photo. The morning was fairly overcast, however, the Egret image showed two hot spots -- on the top of its head and its shoulder, both of which I recovered in LR3. (I had no more room at the top of the photo, by the way)
I'm going to agree with Gail, but I know it was not possible to go lower. Sometimes I just hope for the subject to come closer for portraits in a case like this. Neat to see the "golden slippers" through the water.
