The mystery of how migrating animals find their way over unfamiliar terrain has intrigued people for centuries, and has been the focus of productive research in the biological sci ences for several decades. Whether or not the earth's magnetic field had anything to do with their navigational abilities has sufaced and been dismissed several times, beginning at least in the mid to late 1800s. This topic generally remained out of the mainstream of scientific research for two reasons: (1) The apparent irreproducibility of many of the be havioral experiments which were supposed to demonstrate the existence of the magnetic sense; and (2) Perceived theoretical difficulties which were encountered when biophysi cists tried to understand how such a sensory system might operate. However, during the mid to late 1960s as the science of ethology (animal behavior) grew, it became clear from studies on bees and birds that the geomagnetic field is used under a variety of conditions. As more and more organisms were found to have similar abilities, the problem shifted back to the question as to the basis of this perception. Of the various schemes for trans ducing the geomagnetic field to the nervous system which have been proposed, the hy pothesis of magnetite-based magnetoreception discussed at length in this volume has per haps the best potential for explaining a wide range of these effects, even though this link is as yet clear only in the case of magnetotactic bacteria.

The alarm calls of birds make them difficult for predators to locate, while the howl of wolves and the croak of bullfrogs are designed to carry across long distances. From an engineer's perspective, how do such specialized adaptations among living things really work? And how does physics constrain evolution, channeling it in particular directions? Writing with wit and a richly informed sense of wonder, Denny and McFadzean offer an expert look at animals as works of engineering, each exquisitely adapted to a specific manner of survival, whether that means spinning webs or flying across continents or hunting in the dark-or writing books. This particular book, containing more than a hundred illustrations, conveys clearly, for engineers and nonengineers alike, the physical principles underlying animal structure and behavior. Pigeons, for instance-when understood as marvels of engineering-are flying remote sensors: they have wideband acoustical receivers, hi-res optics, magnetic sensing, and celestial navigation. Albatrosses expend little energy while traveling across vast southern oceans, by exploiting a technique known to glider pilots as dynamic soaring. Among insects, one species of fly can locate the source of a sound precisely, even though the fly itself is much smaller than the wavelength of the sound it hears. And that big-brained, upright Great Ape? Evolution has equipped us to figure out an important fact about the natural world: that there is more to life than engineering, but no life at all without it.

“Just astonishing . . . Our natural navigational capacities are no match for those of the supernavigators in this eye-opening book.”—Frans de Waal, The New York Times Book Review Publisher's note: Supernavigators was published in the UK under the title Incredible Journeys. Animals plainly know where they’re going, but how they know has remained a stubborn mystery—until now. Supernavigators is a globe-trotting voyage of discovery alongside astounding animals of every stripe: dung beetles that steer by the Milky Way, box jellyfish that can see above the water (with a few of their twenty-four eyes), sea turtles that sense Earth’s magnetic field, and many more. David Barrie consults animal behaviorists and Nobel Prize–winning scientists to catch us up on the cutting edge of animal intelligence—revealing these wonders in a whole new light.

Elephants are able to sense an earthquake before it happens. How are they able to do this? They can feel the seismic vibrations in the earth through their trunk and their feet. Readers learn how elephants use these vibrations to communicate with each other and sense danger. Fun, memorable facts presented throughout the text address elephants and other animals with similar sensory adaptations, including snakes and spiders. Informative text and a detailed graphic organizer introduce readers to important science curriculum concepts, such as animal adaptations and seismic waves. Vibrant photographs of a variety of animals keep readers engaged as they learn.

Biological effects of magnetic fields have been studied in many animals and plants. The magnetic fields were of a wide intensity range and, as alternating fields, of a wide frequency range and of a variety of impulse shapes. Effects on the cellular level, on bio chemical processes, growth and development, interactions with physiology, sensory input, reflexes and rhythm control, to name just a few, have been reported. Numerous magnetically induced changes in behavior have also been described. Recently, the amount of literature covering biological effects of magnetic fields has been rapidly increasing. By now it has grown to such an extent that it can no longer be covered in one volume. Most reviews specialize and focus on particular aspects and/or types of fields or effects. For example, the book edited by MARET et al. (1986) gives an overview on biological effects of steady magnetic fields, MISAKIAN et al. (1993) reviewed those of extremely low frequency magnetic fields, focusing on in vitro effects. BERN HARD (1992) reported on 'electromagnetic smog' in view of pos sible effects on human health and well-being, and a series of papers edited by AMEMIYA (1994) summarizes Japanese research on effects of electromagnetic fields ranging from extern ely low to ultra-high frequencies. TENFORDE (1979) and ADEY (1981) sum marized and discussed tissue interactions, REITER (1993a) neu roendocrine and neurochemical changes associated with various kinds of electromagnetic fields.

Meet the ladies: a flock of smart, affectionate, highly individualistic chickens who visit their favorite neighbors, devise different ways to hide from foxes, and mob the author like she's a rock star. In these pages you'll also meet Maya and Zuni, two orphaned baby hummingbirds who hatched from eggs the size of navy beans, and who are little more than air bubbles fringed with feathers. Their lives hang precariously in the balance-but with human help, they may one day conquer the sky. Snowball is a cockatoo whose dance video went viral on YouTube and who's now teaching schoolchildren how to dance. You'll meet Harris's hawks named Fire and Smoke. And you'll come to know and love a host of other avian characters who will change your mind forever about who birds really are. Each of these birds shows a different and utterly surprising aspect of what makes a bird a bird-and these are the lessons of Birdology: that birds are far stranger, more wondrous, and at the same time more like us than we might have dared to imagine. In Birdology, beloved author of The Good Good Pig Sy Montgomery explores the essence of the otherworldly creatures we see every day. By way of her adventures with seven birds-wild, tame, exotic, and common-she weaves new scientific insights and narrative to reveal seven kernels of bird wisdom. The first lesson of Birdology is that, no matter how common they are, Birds Are Individuals, as each of Montgomery's distinctive Ladies clearly shows. In the leech-infested rain forest of Queensland, you'll come face to face with a cassowary-a 150-pound, man-tall, flightless bird with a helmet of bone on its head and a slashing razor-like toenail with which it (occasionally) eviscerates people-proof that Birds Are Dinosaurs. You'll learn from hawks that Birds Are Fierce; from pigeons, how Birds Find Their Way Home; from parrots, what it means that Birds Can Talk; and from 50,000 crows who moved into a small city's downtown, that Birds Are Everywhere. They are the winged aliens who surround us. Birdology explains just how very "other" birds are: Their hearts look like those of crocodiles. They are covered with modified scales, which are called feathers. Their bones are hollow. Their bodies are permeated with extensive air sacs. They have no hands. They give birth to eggs. Yet despite birds' and humans' disparate evolutionary paths, we share emotional and intellectual abilities that allow us to communicate and even form deep bonds. When we begin to comprehend who birds really are, we deepen our capacity to approach, understand, and love these otherworldly creatures. And this, ultimately, is the priceless lesson of Birdology: it communicates a heartfelt fascination and awe for birds and restores our connection to these complex, mysterious fellow creatures
