Today, 1,200 bird species face extinction and there are 190 classified as Critically Endangered. If we don’t act now, we could lose them within 10 years. Birds are now facing a wider range of threats than ever before, almost entirely as a result of human activity. Being widespread, well studied, and highly responsive to environmental change, birds are very valuable indicators of the health of the natural world. They tell us what is happening to everything else. If birds go extinct so will many other species.
