As humanity steadily decimates the global bird population, scientists and scholars are discovering that birds may have played a greater role in shaping human evolution than primates. Our distant ancestors imitated birdsong to develop language and followed bird migration flyways around the world, consistently settling in prime bird habitat. Church of Birds is an eco-history of human evolution that’s supported by recent scientific discoveries, ancient myth, and sacred texts. Across dozens of cultures, migratory birds were seen as divine agents of a benevolent sun, delivering seeds to the landscape in spring and guiding souls to a heavenly paradise in the fall. These mythic roles were ultimately incorporated into Judaism, Christianity, and Islam.
