500 bird species face extinction within the next century - University of Reading

Climate change and habitat loss could cause more than 500 bird species to go extinct in the next 100 years, researchers from the University of Reading have found.

Their study, published today (Tuesday, 24 June) in Nature Ecology & Evolution, reveals this number is three times higher than all bird extinctions recorded since 1500 CE. The extinction of vulnerable birds such as the bare-necked umbrellabird, the helmeted hornbill, and the yellow-bellied sunbird-asity would greatly reduce the variety of bird shapes and sizes worldwide, harming ecosystems that depend on unique birds like these for vital functions.

The scientists found that even with complete protection from human-caused threats like habitat loss, hunting and climate change, about 250 bird species could still die out.

Kerry Stewart, lead author of the research from the University of Reading, said: “Many birds are already so threatened that reducing human impacts alone won't save them. These species need special recovery programmes, like breeding projects and habitat restoration, to survive. We face a bird extinction crisis unprecedented in modern times. We need immediate action to reduce human threats across habitats and targeted rescue programmes for the most unique and endangered species."
