I agree. I put thistle seed and black oil sunflower seed in the hanging feeders. Quite a lot ends up on the ground, but the ground-feeding birds and the squirrels clean it up quite well.
I toss red millet mixed with a little white millet around on the ground, because I have a mixed flock of sparrows that I like to have around. The flock is made up mostly of gold-crowned and white-crowned sparrows, along with a couple of other species ... and of course, a few house sparrows. I was surprised that there weren't more house sparrows. There are only about a dozen house sparrows in the entire flock, which is quite large. They all really love red millet, though. Lazuli buntings seem to like millet, too, as do juncos. I especially love to see the Lazuli buntings!
I toss some cracked corn on the ground along under the hedge for the Rufous-sided towhees.
Ants are drawn to the seed on the ground, and flickers come to eat the ants. There's always a lot of activity out there.
I think the birds come just as much for the water, though. I must be the only person who offers water, because when the temperatures are below freezing, my birdbaths are very busy places, just as they are during the heat of the summer.
