small tan bird with bright yellow tail markings
I live in SW Wisconsin. I have a new bird--about the size of a chipping sparrow, maybe even a little smaller, wren-like in posture with tail straight up. Very shy but hanging around my birdbath. It is mostly buff or light brown, with bright yellow along the side edges of the tail, which is tipped with black. Also has a black line through eyes. Not in any of my bird books or online ID. Thanks!
