Junco

a bird of the finch or sparrow family. The common junco is a slate-colored bird with light under parts and a light bill. It may be known by two white outside tail feathers displayed in flight. The junco breeds in the evergreen belt of Canada and the eastern United States. In winter these little "gray-robed monks and nuns" go southward as far as the heavy snows go. The junco is one of the most popular and well known of the snowbirds.
