I say simply a Sparrow but the Chipping Sparrow (Spizella passerina) is one of my favourite North American Sparrow species. But they never seem to want to cooperate with me if I’m behind a camera.
This particular Chipping Sparrow appeared in the yard, messed about hiding behind feeder poles and blades of grass before flying up onto the roof. After mocking me from the roof for a while it flew down and posed for a couple of photos before starting to avoid me again.
