Dark Eyed Junco birds, a genus of small grayish American sparrows. are very popular in the Clingmans Dome area. Adults generally have gray heads, necks, and breasts, gray or brown backs and wings, and a white belly, but show a confusing amount of variation in plumage details. The white outer tail feathers flash distinctively in flight and while hopping on the ground. The bill is usually pale pinkish.
