Stealth Bird Week .2 / by Dave Hileman

Another bird found in Denali National Park, the Willow Ptarmigan. This is summer coloration but in the winter it is almost entirely white. Occasionally called the Willow Grouse it is one of the strangest calls of any bird I have heard. I was thrilled to see this new species for me several times in Alaska. I would like to see one in the winter, unfortunately that would mean that it is also cold.
