I believe this is the first Common Merganser I have seen. It was very wary and difficult to get a photograph of. The day was overcast and not very bright, which contributed to the overall effect if this image. Still, I felt rewarded for visiting Delta Ponds again.

Some information about the Common Merganser:

"The Common Merganser is the largest merganser in North America. It has a hooked upper bill with sharp saw-like edges to help hold onto slippery fish. The male has greenish-black head, a long thin neck, white breast, and gray rump, black back, and red feet. In flight, you might be able to see a white patch on the upper surface of the entire wing. In eclipse the male resembles the female but still has his white wing patch. The female Common Merganser has a gray body and sides, crested reddish-brown head, white throat and chest, and a large white wing patch. Her bill and feet are also red. The young male resembles the female." - http://www.birdinginformation.com/birds/ducks/common-merganser/
