On Golden Pond

I am having fun with my 400mm telephoto lens on my afternoon walks!  Of course, this was not on golden pond, this was Hempstead Harbor.  It was perfect light with the sun near the horizon, which gave this golden color to the light reflecting on the water.  As some Mallards were swimming by, I followed them as they swam into the light, which was actually a narrow band of reflection.  So I followed them along as they trailed diamonds in the water, until I got this shot.
