Finally, however, on a blustery January morning, we paddled across the first of six filtration-marsh projects that waterfowlers hope will relieve the crowding and intense pressure typical of most public duck-hunting opportunities in southern Florida. We spread two dozen decoys across a wind-sheltered hydrilla patch and then concealed ourselves in the fringing cattails. Come sunrise, the ducks must have been cold and hungry. Late-season ducks this far south along the eastern flyway typically cast at least one wary eye over decoys first, but these birds poured into the food-rich lee. Within an hour, 11 species lay in the canoe, including a blue-winged teal, a green-winged teal, a pair of Florida mottled ducks, a drake wigeon, a gadwall hen, a shoveler, a Fulvous whistling duck, a drake redhead, a ringbill (ringneck) and a bluebill (scaup).
