The bird is a yellow-rumped warbler. They are incredibly common across much of North America, especially in spring and fall migration. You likely know that there are two races, Myrtle's with the white throat, and Audubon's with the yellow throat. Myrtle's mostly eastern and Audubon's dominate in western U.S. In fall they can be really drab and I.D. tougher. They all have the "yellow rump", and eye ring, most have a yellowish flank area and some degree of streaking on the flanks.
Re the man-made features, I say get the best and most interesting shots that you can get, and screw rules about details.
Good birding. Steem on!
