When hunting in black duck country, a thermos full of coffee is mandatory—not for the caffeine or warmth but to keep your spirits up. On the marshes where black ducks live, they make up the bulk of every bird you see. The problem is, they want nothing to do with you. Of the over two dozen duck species that migrate along the Atlantic Flyway, the black duck is the only one rumored to be able to count. Too many decoys, and a black duck won’t commit. Too few decoys, and they’ll keep buzzing. The lucky number? Seven, according to old-timers from Long Island Sound. Even-numbered decoy spreads, they insist, indicate a duck hunter. Now, I can’t attest to the black duck’s ability to count, but I do know they’re tough suckers to hunt. They’re brutally wary. They shy away from most natural-looking decoy spreads, almost always avoid a duck call, and fly in such small numbers that one shot is usually all you get. To avoid heartbreak and frustration, hunters must ditch the usual duck hunting playbook and adopt strategies honed over generations of being outwitted.
