Tomorrow is Earth Day, a day to honor and strengthen our resolve to preserve the precious planet we all share. But with one-third of U.S. birds—including the beloved Rufous Hummingbird—in need of urgent conservation action, we’re not waiting to act. Because birds have been telling us that we must take action on climate—and because we have listened—we’re already working to create a safer, more hopeful future for birds and for our planet.

Just how many birds we’re able to protect depends on the steadfast support from caring bird lovers like you. So please, make your monthly donation before midnight tomorrow while your first gift will be matched, up to $30,000, to go twice as far for birds and the places they need.
