Black sunflower seeds are highly recommended for use in bird feeders because they attract a wide variety of birds, have a high ratio of meat to shell, and are high in fat content. Other common birdseeds include niger, a favorite of goldfinches, millet for sparrows and juncos, and safflower for cardinals, among others.
Commercial bird food
A wide variety of commercial bird food is available to bird owners. However, bags of mixed birdseed often combine attractive bird food like sunflower seeds with "filler" materials that birds enjoy less. Birds tend to pick out their favorite seeds and simply leave the rest uneaten.
