I only got to spend a short amount of time with this particular bird. It was fun watching him jump off the ice and disappear into the moving water and a short while later leap out of the water with what appeared to be small green caddisfly larvae pulled from their sandy cases. They were eaten quickly and the bird returned to the ice edge for another round of foraging.
This stretch of the Lamar River has a pretty high density of American Dippers and they appear to each occupy about a 10 meter portion of open water. There was also a small flock of Barrow's Goldeneyes near where I was, but I didn't get a chance to get any photos of them. Next year!
I did find time to take a few shots of this Bighorn ram too. He must have been pretty active earlier this fall - both sides of his horns were broomed pretty good.
