Audubon research shows that most North American birds are climate-threatened, with the beloved Scarlet Tanager and 388 other species at increasing risk of going extinct. This potential loss isn’t a distant danger but rather one that’s already in progress: Three billion birds have vanished in less than a single human lifetime.

Unless urgent climate action is taken soon, the world could become uninhabitable for many bird species. But with the generous support of people like you, we can build a more sustainable future for birds and people alike. Please, provide for birds’ defense with an annual gift that automatically renews today. Until midnight, your first gift will be matched up to $20,000, thanks to a group of generous donors.
