Bird Population Monitoring

Bird Banding

Bird banding is our primary research tool. We band at least five mornings a week during fall migration (mid-August to November) and less frequently during the spring migration. We have banded over 31,000 birds of 139 species.  Read more and view banding results here.


Winter Bird Population Survey

This annual survey helps to determine the effects of weather on survival, winter territories, and winter site fidelity. Begun on campus in 1993, it runs from 20 December to 20 February. Read more and view past results here.


Christmas Bird Count

The Detroit River Michigan and Ontario Christmas Bird Count, held annually on January 1st, includes Dearborn and adds to the winter survey data. RRBO coordinates the Dearborn team. Read more and view past results here.


Migration surveys

Daily spring migration counts and help monitor the species and numbers of migrating birds throughout the campus and nearby areas. For information on the latest species seen on our surveys, visit our Latest sightings page.
