@fiveoaksresearch: I can already hear those decrying corn, but those who have spent enough time chasing ducks in the woods know better. These mallards are diving to feed on acorns that fell from a Delta post oak overhanging this slough. A boom acorn crop can mean the difference between having a few ducks in the woods and seeing hordes of them. Acorns are an important, energy-rich food for wintering mallards and one of the many reasons healthy bottomland hardwood forests remain such an important part of the Arkansas landscape.
