Canvasback Ducks at DeKorte

We went to the DeKorte Park's Lyndhurst Nature Reserve today. We didn't see the northern shrike that has been reported there, but we did see quite a few canvasback ducks. Most were resting with their heads on their backs, but we found a male (top photo) and a female (second photo) that were awake. The male's head looks brilliant when the sun catches it.
