I was fortunate to watch this Eastern Towhee (Pipilo erythrophthalmus) for quite a bit of time the other day. The common name is onomatopoeic, based on one of the common calls. The species name is Greek for red eye (distinctive on birds that live in the northern part of the east coast but lacking on southern residents, like this one).
They spend most of their time on the ground, very busily shuffling through leaf litter looking for seeds and insects. This quick hopping and scratching behavior made it difficult to capture a decent photo. Many of them turned out like the one below.
