Walking on the tundra today I heard a whistling noise and stopped, thinking it was perhaps a young Yellow-bellied Marmot. I scanned the rock outcrops 30 yards away and then looked again at some closer rock piles, but could not find anything despite continuing the hear the calls. I thought; “those sound very close” and looked down and saw that I was standing 4 feet away from this mama White-tailed Ptarmigan. She ignored me and watched her chicks as they ran around, frequently coming back to Mom to snuggle under her.
