Where: Mississippi River basin states.

What: More than a dozen maps have been produced to illustrate the parks, overlooks, and other spots where birders can search out wildlife along both sides of the 1,366-mile Upper Mississippi River in Minnesota, Wisconsin, Iowa, Illinois, and Missouri. Sites are now being selected in the five Lower Mississippi River valley states to connect the trail to the Gulf of Mexico.

Look for: Tundra swan
