Willow Ptarmigan -- feeding on willow, no less (first photo).
Males were in their courtship plumage, red-brown head and white body.
Females had fully molted into their summer brown.
Returning in the snow from a successful (but photoless) trek
to find a Bristle-thighed Curlew, we found this American Golden-Plover
who must have had a nest nearby considering how it stood its ground.
You can see how effective its camouflage would be if it put its head down.
This Surfbird was far from any surf.
American Dipper. Note that when it blinks, it shows its white eyelid.
