If you are so inclined, here are two photos, both from behind the bird, which flew away as I was trying to come around the front for a photo.

When it flew in and I saw it in the corner of my eye I was thinking American Kestrel (have those on the brain lately) but as I got closer it appeared bigger than that. The coloring wasn't right either. I can't really figure this one out. The yellow eyes must be a decent clue but I can't think of a bird with yellow eyes in the 10-14 inch size range.

Anyone?
