An American Wigeon calmly swims through first ringlets of raindrops from a coming storm. The feathers of ducks are better than Goretex because they preen themselves with an oil produced by a gland near their rump. This causes water to bead up and roll off. Combined with the downy feathers underneath, ducks are perfectly warm in inclement weather as well.
