Mallard Migration Status

Every week, over 100 Ducks Unlimited biologists, wildlife managers and other experts rank the progress of mallard migration in their areas. They compile their data to bring you a map showing the status of the mallard migration.

Limitations
These rankings do not depict mallard abundance; they indicate the relative progression of the fall migration. Estimated peak numbers of mallards may be lower or higher than average numbers during previous years due to annual variations in local wetland and environmental conditions. As a result, a dark color does not necessarily mean that lots of mallards are present in that region.

These maps depict real time estimates of migration without the benefit of waiting until the completion of migration before providing assessments. Revised maps will be posted in February. Some variation in results may also occur depending on the number of experts reporting for a given week.
