The Allen’s Hummingbird is a species in a worrying decline. As a result of habitat loss and degradation, disturbance from people and pets, and climate change, their populations have plummeted by a staggering 88% since 1970. And this unique hummingbird is projected to lose up to 90% of its breeding range by the end of the century if no action is taken to slow climate change.
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.
Birds are already suffering from the effects of climate change—effects that will only intensify unless we change course. But there’s hope in action, and we have practical, effective solutions. Drawing on over a century of expertise, we’re defending key conservation laws like the Endangered Species Act and the Migratory Bird Treaty Act, protecting vital habitats, and pursuing science-based climate work to give birds on the brink their best hope for survival.
