China’s growing army of amateur birdwatchers is a dedicated bunch—and that dedication could eventually pay off in better protection for their feathered friends. A new study uses more than 2 decades of bird sightings by China’s citizen scientists to map the ranges of nearly 1400 species, from the endangered red-crowned crane to the pied falconet. Spinning those maps forward to 2070, researchers have determined what their future ranges might be—and pinpointed 14 priority areas for new nature preserves.
