I borrowed a Nikon D500 w/200-500mm f5.6, didn't realize it was set on Jpeg, this is what came out.

I love white-throated sparrows.
Very nice pose- parallel to the sensor with a nice head turn.
Perch is OK and BG just OK. I would clone out the little circle just above the bird's back.
The main issue I have with this image is that the eye/bill area are not tack sharp and the whites are blown on the forehead and rump.
Looks like critical focus was on the shoulder.
I once shot for a morning on JPEG setting and I was so upset. A hard lesson worth learning and now I always check my camera now before I fire a single shot when starting my morning/afternoon.
