Observed a few days ago in Chicago, Illinois in the middle of the city among a group of house sparrows.
Pictures are a little blurry. Slightly more upright than house sparrows; hopping on the grass. A light brown streak visible above and below the eye. Black spots on the upper chest. I thought it could be a harris sparrow, but not sure. I don't see black on top of the head. Not familiar with midwest birds, so any input would be appreciated!
Thanks!
