Were they perhaps buffleheads? They look black-and-white from a distance.

They looked honest to God like a bunch of Holstein ducks. I tried to take pictures, but due to the non-zoom nature of the camera, you'll have to open the images full size. They still look black-and-white to me:





I always think they look like something Coco Chanel would have designed, if she’d made ducks instead of clothes. Such chic waterfowl.

I like this idea.
