I am guessing it stands for North Stafford for north Stafford county where the picture was taken. Stafford county is refered to as north and south because of school districts and rivalries.
These little Chickadees move so fast and hardly ever sit still for very long, so it's been really hard to get a decent picture. I finally got a "keeper".
Great shot very focused. I just love these little guys and Junco's too.
No unfortunately it's a fixed lens camera. It does have alot of ISO settings & white balance settings and a powerfull 36X (864 MM) zoom lens which I had full out for the humming bird. I was actually about 25 feet away sitting on my pic-nic table with a mini tripod.
