Eventually, this could make trouble to an animal with specific habitat needs like Ohio'n pileated (红冠) woodpecker. Pileated woodpeckers have the nickname carpenter birds for their never-ending natural woodworking. They peck out holes in trees for their nests every year, creating lots of valuable homes for animals like fox squirrels and owls. “They make new nests every year. They won't reuse old ones，” Hu said. “Other animals depend on them.” Pileated woodpeckers are private birds that are more often heard than seen. Studying them can be especially difficult. So Hu turned to citizen science for help. To identify where woodpeckers have been seen, she used eight years of sightings collected by birders and logged into the website eBird, a free online tool and app that anyone can use to record their observations and locations. She overlaid these sightings with remote sensing data and found that corridors along rivers and creeks with abundant mature trees and deadwood helped the birds adjust to their increasingly fragmented urban landscape. “With fragmented forests, many habitats that were once suitable for wildlife are broken up，” Hu said. “Wildlife is unable to find habitat big enough to meet their survival needs. And even if there are suitable habitats, the distance between them can be too great. Wildlife corridors link up these habitat patches. Since wildlife can travel and migrate from one patch to another, the probability of finding food and shelter is higher.” “There are so many species in urban areas that we don't pay attention to, especially when they're not considered vulnerable，” Hu said. “With development chipping away at more forest in this crowded county, the tipping point (临界点) could come quickly and unexpectedly. You can't fix it overnight. It's not just
