Can you tell from the picture? My recollection is that I didn't notice it being any larger than the house finches which are our most common winter visitor. It looks like the chipping sparrows we see in summer, but I read that they are unusual here (Iowa) in winter. I've looked at more than one guide, but can't tell.
CLOSED: Chipping sparrow or American Tree Sparrow?
American Tree - note the grey eyebrow, and the orangey shoulder patch. Also Chipping would still be in winter plumage (brown, not orange, crown) at this time of year.
There's also the bi-colored bill of the American Tree Sparrow.
Resin, I'd not ever paid attention to the shoulder patch before. Another marking to help with the ID. :) Last year we saw our first Chippings the end of March, so it won't be long now.
Thanks for the quick response, Resin. I especially appreciate your telling me what to look for,
