    Yet this influence is not unidirectional, say the authors  of this fascinating book: people profoundly influence crow culture, ecology, and evolution as well. Examining the often surprising ways that crows and humans interact, John Marzluff and Tony Angell contend that those interactions reflect a process of “cultural coevolution.” They offer a challenging new view of the human-crow dynamic—a view that may change our thinking not only about crows but also about ourselves. Featuring more than 100 original drawings, the book takes a close look at the influences people have had on the lives of crows throughout history and at the significant ways crows have altered human lives. In the Company of Crows and Ravens illuminates the entwined histories of crows and people and concludes with an intriguing discussion of the crow-human relationship and how our attitudes toward crows may affect our cultural trajectory. As the authors state in their preface: “Crows and people share similar traits and social strategies. To a surprising extent, to know the crow is to know ourselves."

    What is going on inside the head of a nightingale as it sings, and how does its brain improvise? How do desert birds detect rain hundreds of kilometers away? How do birds navigate by using an innate magnetic compass?Tracing the history of how our knowledge about birds has grown, particularly through advances in technology over the past fifty years, Bird Sense tells captivating stories about how birds interact with one another and their environment. More advanced testing methods have debunked previously held beliefs, such as female starlings selecting mates based on how symmetrical the male's plumage markings are.

Allen Award from the Cornell Laboratory of Ornithology. He also started the first birding camps for young people, which he considers one of his greatest achievements.In One More Warbler, Emanuel recalls a lifetime of birding adventures—from his childhood sighting of a male Cardinal that ignited his passion for birds to a once-in-a-lifetime journey to Asia to observe all eight species of cranes of that continent.

Emanuel writes about the sighting of an Eskimo Curlew, thought to be extinct, on Galveston Island; setting an all-time national record during the annual Audubon Christmas Bird Count; attempting to see the Imperial Woodpecker in northwestern Mexico; and birding on the far-flung island of Attu on the Aleutian chain.

    They attracted followers ranging from Thomas Jefferson, who laid out mastodon bones on the White House floor, to twentieth-century doctors who used their knowledge of new species to conquer epidemic diseases. Acclaimed science writer Richard Conniff brings these daredevil "species seekers" to vivid life. Alongside their globe-spanning tales of adventure, he recounts some of the most dramatic shifts in the history of human thought. At the start, everyone accepted that the Earth had been created for our benefit. We weren't sure where vegetable ended and animal began, we couldn't classify species, and we didn't understand the causes of disease. But all that changed as the species seekers introduced us to the pantheon of life on Earth—and our place within it.
