Book excerpt: A gifted biologist's careful and beguiling study of why cuckoos have got away with tricking other birds into hatching and raising their young for thousands of years. The familiar call of the common cuckoo, “cuck-oo,” has been a harbinger of spring ever since our ancestors walked out of Africa many thousands of years ago. However, for naturalist and scientist Nick Davies, the call is an invitation to solve an enduring puzzle: how does the cuckoo get away with laying its eggs in the nests of other birds and tricking them into raising young cuckoos rather than their own offspring? Early observers who noticed a little warbler feeding a monstrously large cuckoo chick concluded the cuckoo's lack of parental care was the result of faulty design by the Creator, and that the hosts chose to help the poor cuckoo. These quaint views of bad design and benevolence were banished after Charles Darwin proposed that the cuckoo tricks the hosts in an evolutionary battle, where hosts evolve better defenses against cuckoos and cuckoos, in turn, evolve better trickery to outwit the hosts. For the last three decades, Davies has employed observation and field experiments to unravel the details of this evolutionary “arms race” between cuckoos and their hosts. Like a detective, Davies and his colleagues studied adult cuckoo behavior, cuckoo egg markings, and cuckoo chick begging calls to discover exactly how cuckoos trick their hosts. For birding and evolution aficionados, The Cuckoo is a lyrical and scientifically satisfying exploration of one of nature's most astonishing and beautiful adaptations.

Download or read book Diseases of Wild Waterfowl written by Gary A. Wobeser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of wild waterfowl has become increasingly intensive. Many birds now hatch in managed nesting cover or in artificial nesting structures, use man-made wetlands, and winter on crowded refuges while consuming a grain diet The water they use is often limited in supply and may contain residues from its many prior users. Unfortunately, intensified management often results in new problems, among which disease is important There are many similarities between the current form of management used for some waterfowl and that used in domestic animals. In both, the objective is to maintain a healthy, productive population. Dealing with health problems in waterfowl will benefit from combining the skills of veterinary medicine and wildlife ecology. Revisiting this book after 15 years allowed me to consider changes at the interface between the two disciplines. Veterinary medicine traditionally has been concerned with the individual and with treating sick animals, while the ecologist is concerned with populations and the manager has limited interest in treating sick birds. During this period there has been a marked increase in awareness among veterinarians that they have a responsibility in wildlife and conservation biology. Curricula of many veterinary colleges now include material on non-domestic animals and attempt to put disease in an ecological context. Also during this time, waterfowl managers have become more aware of disease as a factor in population biology and there are early attempts to put numbers to "disease" in models of continental waterfowl populations.

Download or read book The Narrow Edge written by Deborah Cramer and published by Yale University Press. This book was released on 2015-04-28 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thousands of ravenous tiny shorebirds race along the water’s edge of Delaware Bay, feasting on pin-sized horseshoe-crab eggs. Fueled by millions of eggs, the migrating red knots fly on. When they arrive at last in their arctic breeding grounds, they will have completed a near-miraculous 9,000-mile journey that began in Tierra del Fuego. Deborah Cramer followed these knots, whose numbers have declined by 75 percent, on their extraordinary odyssey from one end of the earth to the other—from an isolated beach at the tip of South America all the way to the icy tundra. In her firsthand account, she explores how diminishing a single stopover can compromise the birds' entire journey, and how the loss of horseshoe crabs—ancient animals that come ashore but once a year—threatens not only the survival of red knots but also human well-being: the unparalleled ability of horseshoe-crab blood to detect harmful bacteria in vaccines, medical devices, and intravenous drugs safeguards human health. Cramer offers unique insight into how, on an increasingly fragile and congested shore, the lives of red knots, horseshoe crabs, and humans are intertwined. She eloquently portrays the tenacity of small birds and the courage of many people who, bird by bird and beach by beach, keep red knots flying.

Available in PDF, EPUB and Kindle. Book excerpt: In the past half century, deadly disease outbreaks caused by novel viruses of animal origin - Nipah virus in Malaysia, Hendra virus in Australia, Hantavirus in the United States, Ebola virus in Africa, along with HIV (human immunodeficiency virus), several influenza subtypes, and the SARS (sudden acute respiratory syndrome) and MERS (Middle East respiratory syndrome) coronaviruses - have underscored the urgency of understanding factors influencing viral disease emergence and spread. Emerging Viral Diseases is the summary of a public workshop hosted in March 2014 to examine factors driving the appearance, establishment, and spread of emerging, re-emerging and novel viral diseases; the global health and economic impacts of recently emerging and novel viral diseases in humans; and the scientific and policy approaches to improving domestic and international capacity to detect and respond to global outbreaks of infectious disease. This report is a record of the presentations and discussion of the event.
