Song sparrows still visiting many times/day, still the only real visitors

Other than the one goldfinch and one robin sighting in recent weeks, the song sparrow couple are the only birds I'm seeing visit the yard.  The song sparrows visit many times per day, mostly eating of the ground (I'm putting it on plates now) but occasionally out of the pole feeders, and they make great use of the bird baths, both the one attached to the feeder pole and the one on the ground.

Food test today on a plate:  crushed pumpkin seeds, crushed sunflower seeds (no hulls), and millet.  Millet was the clear winner -- it was all eaten whereas still lots of of the pumpkin and sunflower seeds left.
