Why Warbler Watch?

    Spring and Fall Migration:
      Warblers are highly migratory. Most species spend the majority of the year in transit or wintering from the southern-most U.S. to South America. Birds return to their northerly breeding grounds just long enough to breed and raise young. Therefore, to better understand these birds, we need to map not only their summer distribution but their wintering and migration patterns as well. Migration routes vary among species; in fact, many species' migrations are different in the spring than they are in the fall. We know that Tennessee Warblers, for example, move up through the Mississippi and Ohio river valleys in the spring, while in the fall, they typically travel farther east. Blackpoll Warblers likewise take a more easterly path in the fall, with a large portion of these migrants heading out over the Atlantic Ocean north of Cape Hatteras, N.C., and continuing their migration as far south as the Peruvian Andes. Warbler Watch will map the migratory routes of all North American warbler species.

    North American Warbler Breeding Data:

      The warbler breeding data you submit will be used to create a breeding atlas of North American warblers. Many species, such as the Cerulean Warbler, are showing population declines. A few -- Kirtland's and Golden-cheeked -- are already endangered. The information you provide will make an important contribution to this long-term project. Your efforts will help protect endangered warbler species and ensure common warblers remain common. Find out more about each warbler species by visiting the Warbler I.D. guide, which will also take you directly to the Breeding Bird Survey.

Thousands of citizen scientists across North America participated in Warbler Watch last year.

Thanks to their efforts, you can view the amazing migrations warblers make across North America. The animated maps in the Warbler Watch Maproom illustrate the routes and the timing of these continent-wide bird movements.

Your interest and participation is appreciated.
Thanks for watching for warblers!
