Bird migration is ramping up in Michigan: Map shows how many are flying

Bird migration is ramping up in Michigan, indicating the changing seasons and giving birders a chance to see hundreds of species before winter.

Millions of birds are winging their way south across the U.S. en route to their winter homes in the tropics. Live migration maps on the website BirdCast provide a real-time look.

Michigan is unique in that it sits at the intersection of the Mississippi and Atlantic “flyways” — common migration routes followed by scores of birds. More than 380 bird species fly through Michigan each year during fall migration, which spans several months and includes species from songbirds and shorebirds to waterfowl and raptors.

The migration is just getting started but Michigan is already seeing superhighway-level overnight migration, BirdCast shows .
