Gripping narrative non-fiction with STEM and social justice themes that proves cities can be surprisingly wild places--and why understanding urban nature matters. What can city bees tell us about climate change? How are we changing coyote behavior? And what the heck is a science bike? Featuring the work of a diverse group of eleven scientists--herself included!--Dr. Cylita Guy shows how studying urban wildlife can help us make cities around the world healthier for all of their inhabitants. In the process, Guy reveals how social injustices like racism can affect not only how scientists study city wildlife, but also where urban critters are likelier to thrive. Sidebars include intriguing animal facts and the often-wacky tools used by urban ecologists, from a ratmobile to a bug vacuum. Cornelia Li's engaging illustrations bring the scientists' fieldwork adventures to life, while urban ecology challenges encourage readers to look for signs of wildlife in their own neighborhoods. *A Junior Library Guild Gold Standard Selection
