Get your first annual gift matched for birds like the Golden-cheeked warbler.
Right now, more than half of U.S. bird species are in decline. For climate-vulnerable birds like the Allen’s Hummingbird, what matters most is what people like you—people who love birds and are ready to help—do next. We must act immediately to prevent future extinctions and help declining populations recover.
The Allen’s Hummingbird is a species in a worrying decline. Their populations have plummeted by a staggering 88% since 1970—and without immediate climate action, they could lose up to 90% of their breeding range by the end of the century. And sadly, they’re far from alone: Two in three North American bird species are at increasing risk of climate extinction. We must flock together for their protection—before it’s too late.
More than half of U.S. bird species are in decline, with plummeting populations across nearly all habitats.
Most North American birds are under threat, with 389 species at increasing risk of going extinct.
Three billion birds have vanished in less than a single human lifetime.
With more than a century of protecting birds under our wing, we are delivering hands-on conservation efforts that are locally focused and guided by region- and bird-specific expertise. And with thorough research, we’ve demonstrated the positive impact of stewardship and powerful advocacy on birds like the Allen’s Hummingbird and the Golden-cheeked Warbler. Efforts like these help create a blueprint for protecting vulnerable birds across the range of habitats where we work.
