Book Description
In the early years of this century a Scottish doctor speculated on the evolutionary origin of human tears. It seemed to him that with the increase in brain size and cognitive powers of our early ancestors many events in the struggle for existence would be just too distressing to observe. How comforting then, for the mother, distraught by the sight of her child being devoured by a lion, to cloud her vision with a flood of tears! Just so, though if the good doctor had pondered further, the following picture might have occurred to him, comfortable in his speculative armchair, and given him some pause for thought. ' ~ . . . . ~ . . ~ ~ . . •. . u" . . , ~- . ' _ . . . . . . . vii viii SERIES EDITOR'S FOREWORD These stories do not, of course, get us very far in understanding the evolution of tears or anything else, but they do remind us how far the study of behavioural adaptation has come this century. This is, in fact, an exciting time for students of behaviour. The last twenty years have seen a great advance in the theoretical armoury for tackling questions of behavioural evolution and adaptation, and a parallel expansion in empirical studies, particularly in the field. The concepts of inclusive fitness and the evolutionarily stable strategy, for example, have helped to explain major features of social behaviour and have generated entirely new questions and predictions for the field worker to examine.

Book Description
Short listed for the Green Earth book award In early April, as Owen and his sister search the hickories, oaks, and dogwoods for returning birds, a huge group of birds leaves the misty mountain slopes of the Yucatan peninsula for the 600-mile flight across the Gulf of Mexico to their summer nesting grounds. One of them is a Cerulean warbler. He will lose more than half his body weight even if the journey goes well. Aloft over the vast ocean, the birds encourage each other with squeaky chirps that say, “We are still alive. We can do this.” Owen’s family watches televised reports of a great storm over the Gulf of Mexico, fearing what it may mean for migrating songbirds. In alternating spreads, we wait and hope with Owen, then struggle through the storm with the warbler. This moving story with its hopeful ending appeals to us to preserve the things we love. The backmatter includes a North American bird migration map, birding information for kids, and guidance for how native plantings can transform yards into bird and wildlife habitat.

Book Description
This volume is a synopsis of the diversity of all birds. It distills the voluminous detail of the 17-volume Handbook of Birds of the World into a single book. Based on the latest systematic research and summarizing what is known about the life history and biology of each group, this volume is the best single-volume entry to avian diversity available.

Book Description
When many birders go out looking at shorebirds, they see a distant mud flat full of grayish brown birds in various shapes and sizes and have no idea where to begin the identification process. When advanced birders look at that same flock of shorebirds, they can identify the vast majority of birds with a quick binocular scan. Experts use the simplest, most easily observed characteristics--size, structure, behavior, and general color patterns--almost subconsciously, and can identify most birds even before looking carefully at plumage details. Now birders of all levels can learn how to identify these wildly popular birds quickly and with much less effort. This guide provides more than 870 stunning color photographs, sequenced to give a general impression of a species first and progressing to a more detailed image of the bird throughout its life cycle. Captions list characteristics in order of importance, reflecting the thought process that experts use to identify birds.

Book Description
Changes in seasonal movements and population dynamics of migratory birds in response to ongoing changes resulting from global climate changes are a topic of great interest to conservation scientists and birdwatchers around the world. Because of their dependence on specific habitats and resources in different geographic regions at different phases of their annual cycle, migratory species are especially vulnerable to the impacts of climate change. In Bird Migration and Global Change, eminent ecologist George W. Cox brings his extensive experience as a scientist and bird enthusiast to bear in evaluating the capacity of migratory birds to adapt to the challenges of a changing climate. Cox reviews, synthesizes, and interprets recent and emerging science on the subject, beginning with a discussion of climate change and its effect on habitat, and followed by eleven chapters that examine responses of bird types across all regions of the globe. The final four chapters address the evolutionary capacity of birds, and consider how best to shape conservation strategies to protect migratory species in coming decades. The rate of climate change is faster now than at any other moment in recent geological history. How best to manage migratory birds to deal with this challenge is a major conservation issue, and Bird Migration and Global Change is a unique and timely contribution to the literature.

Book Description
Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces) and a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically grounded book that will serve as source both for scientists and for anyone interested in the natural history of the Georgia coast.
