The Biggest Week In American Birding is a 10-day festival in northwest Ohio, “The Warbler Capital of the World!” The festival is held in early May to coincide with the peak of songbird migration. Immerse yourself in spring songbird migration and experience some of the best birding North America has to offer. The festival has something to offer beginner and seasoned birders alike, with bird identification workshops, guided birding trips, daily guided field trips at the world famous Magee Marsh, American Woodcock field trips, keynote presentations, a Birders' Marketplace, and evening socials with free food and music. Come for a few days or stay for the whole 10-day celebration.
