I saw this lonely Greater Scaup at Boat Meadow the other day. It was swimming and diving all alone. I had never seen one before so I clicked a few photographs to try to identify it.

And then when I was at Herring Cove in Provincetown I saw a flock of about 15-20 of them out in the water.

Greater Scaup about 18″ with the male having a gray back and sides of white with a dark green head. Females are a dark brown with a distinct white face.

Have you ever sen a Greater Scaup?
