Straight White Proso Millet. Loved by sparrows, doves, dark-eye juncos, and indigo buntings. We don’t recommend this as your main birdseed as many desirable birds do not like it very much (cardinals, bluejays, chickadees to name a few). But tossing a little on the ground or putting some in a hanging or ground feeder can be a good way to get juncos and indigo buntings when they are in our area.
