I like a fat late season mallard or Canada as much as the next guy but until those northern birds arrive, greenwings are too much fun to hunt. They are plentiful, fast, tasty, nice to look at, and not particularly bright - all good qualities in a duck. Greenwings congregate in very shallow water to feed, often in large numbers. My favorite way to hunt them is to sleep in (all my favorite ways to hunt involve sleeping in), then find a concentration of teal, flush them, and throw out a few decoys. Usually I don't have to wait long until they start coming back, first in two and threes, then by the flock. More often than not, the first ducks reappear before I'm finished setting up. Then it's just a question of hiding in the weeds, shooting straight, and hoping I brought enough shells.
