Three ptarmigans were secured on the summit of a round topped mountain They were all males and were still in the white winter plumage on May 31. They were evidently breeding or just going to. At this date the q was almost brown but still had a few white wing feathers. The males would fly out over the mountainside, hover a moment and then swoop down with great speed and alight on a rock. Their movements were accompanied at intervals by a rasping cry similar to the sound pro- duced by running a nail over a stiff comb. The bright orange comb over the eye was very prominent at this date and a few brown feathers were beginning to show on the head and necks of 2 individuals.
