Aerial surveys this November showed 20 times more ducks on Lake Chautauqua than during the same period last year. The Green-winged Teal made up the majority of those waterfowl, with conditions on the lake this year being favorable. INHS Waterfowl Biologist Randy Smith said, "Green-winged teal like it when the water is so shallow that they can stand up, just an inch or two deep with lots of vegetation." This year's surveys have found that Lake Chautauqua has more than one third of all the ducks at the 16 sites sampled in the Lower Mississippi River Valley.
