Some ducks moving south in winter seek new places where they compete less for resources. When they stumble onto a new fertile land their cohorts inevitably come next in droves.

Because of variations in weather and wetland environment, waterfowl migration patterns may alter to some extent. With different sections producing needed food and resources, water fowl may discover better routes for their yearly migration. This movement in waterfowl migration design may affect waterfowl hunting success in some areas of the nation. With six years of record breaking autumn flights there is no promise that water fowlers will see a plentiful number of birds in front of their blinds.

This progress in wetland and waterfowl research may show the affect on conservation and water fowl hunting in the years to come. The wide open wetland restoration plans serve as habitat for waterfowl and a greater task for hunters. As nature's most fertile ecosystems, wetlands fosters a healthy contrast of plants and animals, including aquatic life. According to the National Wildlife Federation forty-three percent of the nation's threatened or endangered species are dependent upon wetlands during some stage of their life cycle.

Because of improved wetland habitats for the Blue-winged teal those banded in North America bird watchers observed these ducks as far away as Chile, England, Spain, and Morocco.
