On the Wing

As I've noted, I'm not a birder, but I caught this gull soaring about 50 feet over the Hudson River.  This is one of those "lucky" shots.  The bird was flying in my direction.  I shot this with one with my Canon 24-70mm and cropped it way down. 

The bird's body is dark, as the sun was above and to the left, but I just like the detail in the feathers.
