La emocionante aventura de las aves migratorias y lo que esta revela de nuestro presente y de nuestro futuro. «Un apasionante viaje junto a estos nómadas alados y las personas que los estudian. Un espectáculo». The New York Times La migración de las aves es sin duda uno de los fenómenos más asombrosos y cautivadores que existen en la naturaleza. Hoy conocemos en detalle las proezas fisiológicas que permiten a todo tipo de aves cruzar inmensos océanos y continentes, sobrevolar montañas y mantenerse en vuelo ininterrumpido durante meses. Un libro tanto para especialistas como para observadores de prismáticos y patio trasero, A vista de pájaro pone al alcance de todo el misterio de las migraciones de las aves y por qué es tan importante para entender nuestro lugar en el mundo. Algunas migratorias adormecen la mitad de su cerebro en el vuelo, alternando los hemisferios, para no detenerse en el camino; un minúsculo colibrí es capaz de cruzar todo el golfo de México en un solo vuelo sin escalas; los zarapitos aprovechan las furiosas tormentas estacionales para impulsarse de Canadá a Brasil, y el correlimos, del tamaño de un gorrión, vuela sin parar de Canadá a Venezuela --el equivalente a correr 126 maratones consecutives-- orientándose gracias al campo magnético de la Tierra mediante una forma de entrelazamiento cuántico que sorprendería al propio Einstein. Las últimas décadas de investigaciones científicas han dado lugar a una revolución en nuestra comprensión de las pautas migratorias. Scott Weidensaul, finalista del Premio Pulitzer, transmite con pasión todos estos descubrimientos y curiosidades. En un mundo amenazado por los efectos del cambio climático, el relato de estos milagros ecológicos proporciona una guía inestimable hacia un futuro más sostenible. Este libro es un emocionante homenaje a los millones de aves que, pese a los numerosos obstáculos, siguen dirigiéndose con esperanza hacia el lejano horizonte. ENGLISH DESCRIPTION New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we've learned of these key migrations―how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis―is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela―the equivalent of running 126 consecutive marathons without food, water, or rest―avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth's magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides―and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.

With poetic language and lush oil paintings, children will cheer on the tiny but mighty yellow warbler as she makes her perilous migration journey from the tropics of Central America to the Canadian tundra.

"A thoughtful examination of the machinery of extinction . . . By turns harrowing and elegiac, thrilling and informative." -Michiko Kakutani, The New York TimesThree or four times an hour, eighty or more times a day, a unique species of plant or animal vanishes forever. And yet, every so often one of these lost species resurfaces. "Having adventures most of us can only dream about" (The Times-Picayune), Scott Weidensaul pursues stories of loss and recovery, of endurance against the odds, and of surprising resurrections.

Part natural history, part poetry, Mountains of the Heart is full of hidden gems and less traveled parts of the Appalachian Mountains Stretching almost unbroken from Alabama to Belle Isle, Newfoundland, the Appalachians are one of the oldest mountain ranges in the world. In Mountains of the Heart , renowned author and avid naturalist Scott Weidensaul shows how geology, ecology, climate, evolution, and 500 million years of history have shaped one of the continent's greatest landscapes into an ecosystem of unmatched beauty. This edition celebrates the book's 20th anniversary of publication and includes a new foreword from the author.
