Listen to birds sing as you’ve never listened before, as the world-renowned birdsong expert Donald Kroodsma takes you on personal journeys of discovery and intrigue. Read stories of wrens and robins, thrushes and thrashers, warblers and whip-poor-wills, bluebirds and cardinals, and many more bird. Learn how each acquires its songs, how songs vary from bird to bird and place to place, how some birds' singing is especially beautiful or ceaseless or complex, how some do not sing at all, how the often quiet female has the last word, and why. Hear a baby wren and the author’s own daughter babble as each learns its local dialect. Listen to the mockingbird by night and by day and count how many different songs he can sing. Marvel at the exquisite harmony in the duet of a wood thrush as he uses his two voice boxes to accompany himself. Feel the extraordinary energy in the songs just before sunrise as dawn’s first light sweeps across this singing planet. Hear firsthand the unmistakable evidence that there are not one but two species of marsh wrens and two species of winter wrens in North America. Learn not only to hear but to see birds sing in the form of sonagrams, as these visual images dance across the pages while you listen to the accompanying audio. Using your trained ears and eyes, you can begin your own journeys of discovery. Listen anew to birds in your backyard and beyond, exploring the singing minds of birds as they tell all that they know. Join Kroodsma not only in identifying but in identifying with singing birds, connecting with nature’s musicians in a whole new way. Please note: this ebook includes embedded audio files.

An epic account of the rise and fall of the Silk Road empires The first complete history of Central Eurasia from ancient times to the present day, Empires of the Silk Road represents a fundamental rethinking of the origins, history, and significance of this major world region. Christopher Beckwith describes the rise and fall of the great Central Eurasian empires, including those of the Scythians, Attila the Hun, the Turks and Tibetans, and Genghis Khan and the Mongols. In addition, he explains why the heartland of Central Eurasia led the world economically, scientifically, and artistically for many centuries despite invasions by Persians, Greeks, Arabs, Chinese, and others. In retelling the story of the Old World from the perspective of Central Eurasia, Beckwith provides a new understanding of the internal and external dynamics of the Central Eurasian states and shows how their people repeatedly revolutionized Eurasian civilization. Beckwith recounts the Indo-Europeans' migration out of Central Eurasia, their mixture with local peoples, and the resulting development of the Graeco-Roman, Persian, Indian, and Chinese civilizations; he details the basis for the thriving economy of premodern Central Eurasia, the economy's disintegration following the region's partition by the Chinese and Russians in the eighteenth and nineteenth centuries, and the damaging of Central Eurasian culture by Modernism; and he discusses the significance for world history of the partial reemergence of Central Eurasian nations after the collapse of the Soviet Union. Empires of the Silk Road places Central Eurasia within a world historical framework and demonstrates why the region is central to understanding the history of civilization.
