Bird Migration

Bird migration is one of the most astonishing feats in the natural world. Millions of birds migrate, often over very large distances, to benefit from seasonal resource surpluses and to avoid predators and competitors. The aim of this study is to survey the phenomena.

Avian Migration

P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In M...

Seeking Refuge

Each fall and spring, millions of birds travel the Pacific Flyway, the westernmost of the four major North American bird migration routes. The landscapes they cross vary from wetlands to farmland to concrete, inhabited not only by wildlife but also by farmers, suburban families, and major cities. In the twentieth century, farmers used the wetlands to irrigate their crops, transforming the landscape and putting migratory birds at risk. The U.S. Fish and Wildlife Service responded by establishing a series of refuges that stretched from northern Washington to southern California. What emerged from these efforts was a hybrid environment, where the distinctions between irrigated farms and wildlif...

Animals and Humans

Exploring the relationship between animals and humans in Scandinavia from the Roman Iron Age to the Viking Period, this book interprets Old Norse mythology in which imaginary creatures with strong characters were invented and examines the importance of animals in the human world. According to Old Norse perceptions, real and fantasy animals in Midgard became mouthpieces for human characteristics and reflections of people's social position. With the aid of animals, humans could also show who they really were as well as control higher powers. Combining results from archaeology and Old Norse texts, this account discusses the functional, symbolic, and cognitive meanings of animals and the implications of animal rights.

Population Biology of Passerine Birds

Population Biology of Passerine Birds is an up-to-date synthesis of the most recent developments in its field, especially in the framework of modern life history theories. Major topics include quantitative genetics, ecological physiology, the study of social structures using individually marked birds in the wild, and finally biometry, which allows to quantify such important parameters as survival at different stages of life and to create a model of the overall demography of the populations.

Bird flight has always intrigued mankind. This book provides an up to date account of our existing knowledge on the subject, as well as offering new insights and challenging some established views. A brief history of the science of flight introduces the basic physical principles governing aerial locomotion. A treatment of flight-related functional morphology concentrates on the difference in shape of the arm and hand part of the wings, on the structure and function of tails, and on the shape of the body. The anatomy and mechanical properties of feathers receive special attention. Aerodynamic principles used by birds are explained in theory by simply applying Newton's laws, and in practice by...

Long Hops

In Long Hops, physicist Mark Denny explains, in a clear, conversational style, the science of bird migration—from the intricacies of bird aeronautics to the newly unraveled mysteries of their magnetic compasses. While providing wherever possible examples of indigenous Hawaiian species, the book surveys the migration phenomenon as a whole, showing that birds are breathtaking works of engineering with spectacular capabilities for long-distance flights. Each year thousands of these hardy migrants fly 2,500 miles nonstop from Alaska to Hawai‘i. How do they endure such marathon journeys, and how on earth do they know which direction to travel over featureless ocean? In fact, many migratory jo...

Ten Thousand Birds

A beautifully illustrated history of modern ornithology Ten Thousand Birds provides a thoroughly engaging and authoritative history of modern ornithology, tracing how the study of birds has been shaped by a succession of visionary and often-controversial personalities, and by the unique social and scientific contexts in which these extraordinary individuals worked. This beautifully illustrated book opens in the middle of the nineteenth century when ornithology was a museum-based discipline focused almost exclusively on the anatomy, taxonomy, and classification of dead birds. It describes how in the early 1900s pioneering individuals such as Erwin Stresemann, Ernst Mayr, and Julian Huxley rec...
