White-crowned sparrows?

Leaving for work this morning, rustling sounds in the frost-bitten swamp sunflowers caught my attention. I'd seen some goldfinches foraging for seeds there last weekend. They're dull in color now, nothing like their spring and summer colors. But these birds were foraging on the ground, poking around in the leaf litter. There were probably 5 or 6 of them in a small area, joined by a Eastern Towhee kicking the leaf litter.

They scuffled around a bit like the towhee, kicking the litter, bringing up seeds to eat. Their distinctive striped heads seemed to fit white-crowned sparrows, but I didn't have my binoculars with me as I left the house!
