There are four major flyways in North America, paths birds follow in spring / fall migration. They are shown on this map. Minnesota is outlined for easier viewing. The symbols represent waterfowl, but flyways accommodate bird migrants of all species. You can see that we are on the western edge of the Mississippi flyway, birds following the Mississippi River to our southern border, some coming north, others branching east as they head north along both sides of Hudson's Bay, most going west.
