Trish O’Kane never expected to be a birder. It was a lone red cardinal and a bumptious cast of house sparrows that changed everything for O’Kane after Hurricane Katrina shattered her life in New Orleans. Watching birds thrive throughout the devastated city became her salvation and set her on a new path. Soon O’Kane found herself pursuing an environmental science PhD in Wisconsin, where she became a full-on bird obsessive—logging hours and hours in a stunningly diverse urban park, filling field notebooks with observations of bird doings and dramas, and volunteering in a wildlife rehabilitation center bird nursery. But it wasn’t until that park, her bird-watching haven, was threatened with development that O’Kane became an environmental activist. Taking her cues from the birds, she mustered a mighty flock of fellow human park lovers to raise their voices and save the park.
