Common Mergansers on the Brandywine

Though not quite as stunning as their cousins, the Hooded Mergansers.  I enjoy watching the Common Mergansers and other ducks that spend some time on the Brandywine this time of the year.  The males are the two in the front with the green heads and the fairly white bodies.  The female is tailing behind with the brownish head and the body with more of a greyish tint.  They were hanging out with the geese this morning!
