Red-winged Blackbird About the Red-winged Blackbird Migration Study The return of the red-winged blackbird to cattail marshes all over North America is a welcome sign spring. Students can track redwing migration all over the continent, because in areas where redwings overwinter, they stay in fields, pastures, and agricultural areas until they shift into spring behavior and return to marshes. How to Participate Let us know when YOUR redwings first return. This year we want your first redwing sightings, and are also interested in a lot of other redwing behavior sightings.
