From the cave walls at Lascaux to the last painting by Van Gogh, from the works of Shakespeare to those of Mark Twain, there is clear evidence that crows and ravens influence human culture. Yet this influence is not unidirectional, say the authors of this fascinating book: people profoundly influence crow culture, ecology, and evolution as well. John Marzluff and Tony Angell examine the often surprising ways that crows and humans interact. The authors contend that those interactions reflect a process of "cultural coevolution."

New research indicates that crows are among the brightest animals in the world. And professor of Wildlife Science at the University of Washington John Marzluff has done some of the most extraordinary research on crows, which has been featured in the New York Times, National Geographic, and the Chicago Tribune, as well as on NPR and PBS. Now he teams up with artist and fellow naturalist Tony Angell to offer an in-depth look at these incredible creatures - in a book that is brimming with surprises.

With predictions of a human population of more than nine billion by the middle of this century and 11 billion by 2100, we stand at a crossroads in our agricultural evolution. In this clear and engaging book, wildlife biologist John M. Marzluff takes a personal approach to sustainable agriculture. He travels to farms and ranches across North and Central America, including a Nebraska corn and soybean farm, California vineyards, cattle ranches in Montana, and small sustainable farms in Costa Rica, to understand the unique challenges and solutions to sustainable food production.
