Taken a week ago, this is a juvenile Chipping Sparrow in the yard. It must have been a very late brood, the adults had been feeding three young a few days before this photo was taken.
This juvenile is already looking after itself as it searches for something to eat in the grass. They will soon be heading south for the winter.
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.
