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 birds. 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 CD.
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.

A retired biology professor at the University of Massachusetts, Donald Kroodsma's work on bird song is legendary. His book The Singing Life of Birds won the 2006 John Burroughs Medal Award and the American Birding Association's Robert Ridgway Distinguished Service Award for excellence in publications pertaining to field ornithology. In 2003 the American Ornithologits' Union called him the "reigning authority on the biology of avian vocal behavior." Kroodsma received his Ph.D. at Oregon State University and has traveled all over North and South America researching bird song. He is a Fellow of the American Ornithologists' Union and the Animal Behavior Society and has published hundreds of academic and popular articles.Excerpt. © Reprinted by permission.

SOMEWHERE, ALWAYS, the sun is rising, and somewhere, always, the birds are singing. As spring and summer oscillate between the Northern and Southern Hemispheres, so, too, does this singing planet pour forth song, like a giant player piano, in the north, then the south, and back again, as it has now for the 150 million years since the first birds appeared.
Ten thousand species strong, their voices and styles are as diverse as they are delightful. Some species learn their songs, just as we humans learn to speak, but others seem to leave nothing to chance, encoding the details of songs in nucleotide sequences in the DNA. Of those that learn, some do so only early in life, some throughout life; some from fathers, some from eventual neighbors after leaving home; some only from their own kind, some mimicking other species as well. Some species sing in dialects, others not. It is mostly he who sings, but she sometimes does, too. Some songs are proclaimed from the treetops, others whispered in the bushes; some ramble for minutes on end, others are offered in just a split second. Some birds have thousands of different songs, some only one, and some even none. Some sing all day, some all night. Some are pleasing to our ears, and some not.
It is this diversity that I celebrate. How the sounds of these species differ from each other is the first step to appreciating them, of course, but those questions quickly give way to “why” questions. Why do some learn and others not? Why do dialects occur in some species and not others? Why is it mainly the male who sings? It is these and similar “why” questions that so intrigue us biologists as we try to understand the individual voices that contribute to the avian chorus.
In writing about our singing planet, I can focus on only a few of its voices. The thirty stories told here are personal journeys, ones that I have traveled over the past thirty years in my quest to understand the singing bird.
Many are based on my own research and are years in the making. Others are based on just several days’ experience, or even less, as I seek out birds that illustrate the research of friends and colleagues who share my passions. No matter the source, each story is based on listening and on learning how to hear an individual bird use its sounds, and each story illustrates some of the fundamentals of the science called “avian bioacoustics.” Together, I hope these stories and their sounds reveal how to listen, the meaning in the music, and why we should care.
