The sky-blue upperparts of the male Cerulean Warbler are difficult to observe in summer. During that season, the birds stay high in the tops of leafy trees in the eastern United States and extreme southern Canada. The species itself has become harder to observe in recent decades, as its numbers have decreased in parts of its range. And if climate change continues unchecked, 98% of this beloved bird’s current breeding range could be lost.

If ever there was a time when birds needed the support of passionate people like you—it’s right now. And there’s no better opportunity to help bring birds back than today, ahead of Giving Tuesday. We’re counting on 50 committed bird lovers to start a monthly gift before midnight to power our best efforts on behalf of birds. Thanks to a group of generous donors, your first gift will be matched, up to $50,000, for birds in need.
