Tiny, surprisingly hardy birds, greenwings offer sporty shooting throughout the season until shallow marshes freeze. This year, there should be lots to go around wherever there is enough water to float a duck. Teal love mudflats, which should be in abundant supply this year. When you find teal, build a rough blind on the mudflat, throw out a dozen decoys and a spinner and forget about looking up--they'll come in a few feet off the water. You can shoot teal all day, but often the first half hour of shooting light is the best.
