It's bufflehead season. No, I don't shoot them, I like to watch them on the river. They fly down from Canada and winter here in Astoria and in much of the U.S. The male has the unusual white patch on his head like a quarter of a cream pie, and the brilliant white lower half. The female has a white splash on either side of her head. I usually see them not in pairs, but in groups. Sometimes the group is all females, and sometimes it's predominantly female. Their name is a contraction of "buffalo head," which, to me, is just another reason to like these critters.
Our bufflehead ducks are not very tame, and although you can see them on the river often, they keep out of range, and take off when I try to get a good close-up.
