Return of the clowns

The buffleheads have returned to the marsh from their breeding grounds farther north. (I call them clowns because of their playful antics.) A few have been here for a couple of weeks, but were mainly on the sewage lagoon. I caught these two this morning on the marsh proper. Its difficult to tell if these two are adult females or first winter males, as the young ones of both sexes resemble adult females. They'll be seen bobbing around the marsh until it freezes over, at which time some may move to the river and remain through the winter while the remainder may move farther down the coast.
