Wildlife biologist Sophie Osborn has spent a career working with birds that have been a feather’s breadth from extinction in the US. Her new book, Feather Trails: A journey of discovery among endangered birds, focuses on the Hawaiian crow, the California condor and the peregrine falcon (also found globally). We have pushed them to the brink, and Osborn describes in painstaking detail the Herculean work to pull them back.
