The waterfowl survey information presented here is the sum, in most cases, of several areas in the vicinity of the primary survey site depicted on the attached graphic. The timing, magnitude, and duration of the waterfowl migration in Iowa depends not only on the weather and habitat conditions in Iowa, but on weather and habitat conditions in Minnesota and the Dakotas as well.
