Download and read online Sibling Alliances in Juvenile Feral Pigeons in PDF and EPUB "This thesis examines whether juvenile feral pigeons, Columba livia, form sibling alliances when competing for access to a defensible food source. When tested as a flock at a non-depletable column feeder, with room for either one or two birds to feed, siblings associated with each other more often than expected by chance. Frequency of aggression between siblings at these feeders tended to be lower than expected on the basis of their association. Removal experiments showed that sibling presence had a positive effect on relative feeding success at the single column feeder: a juvenile who lost to another juvenile on a one-to-one basis tended, in the presence of its sibling, to lose less badly to, or even beat, that same juvenile. In contrast, presence of the winner's sibling tended not to affect the relative feeding success of competitors. These results support the hypothesis that pigeon siblings form aggressive alliances when competing for food that is defensible." --

Download and read online Feral Cities in PDF and EPUB "[An] entertaining jaunt through city wildlife." —Kirkus Reviews We tend to think of cities as a realm apart, somehow separate from nature, but nothing could be further from the truth. In Feral Cities, Tristan Donovan digs below the urban gloss to uncover the wild creatures that we share our streets and homes with, and profiles the brave and fascinating people who try to manage them. Along the way readers will meet the wall-eating snails that are invading Miami, the boars that roam Berlin, and the monkey gangs of Cape Town. From feral chickens and carpet-roaming bugs to coyotes hanging out in sandwich shops and birds crashing into skyscrapers, Feral Cities takes readers on a journey through streets and neighborhoods that are far more alive than we often realize, shows how animals are adjusting to urban living, and asks what messages the wildlife in our metropolises have for us. Tristan Donovan is the author of two widely praised books, Replay: The History of Video Games and Fizz: How Soda Shook Up the World. His journalism has appeared in many major newspapers, magazines, and web sites. He has a degree in ecology.

Download and read online The Peregrine Falcon in PDF and EPUB The first edition of The Peregrine Falcon was widely recognised as a classic of its kind, documenting not only the species' biology but also the sad tale of its decline due to the impact of pesticides. This extensively revised and enlarged second edition takes full account of important new developments in the story of this bird during the intervening 12 years. It reports one of the few notable successes in wildlife conservation: the full restoration of British and Irish Peregrine populations, and their appreciable recovery in other countries where numbers had also been greatly reduced by the impact of organochlorine pesticides. The pattern of increase in Britain has been extremely varied, from districts where numbers are now far higher than at any time in recorded history, to others where the bird is now at its lowest ebb. The examination of the reasons for these differences helps us to understand the most recent developments in the Peregrine saga. Particular attention has been paid to the recent major advances in our knowledge of Peregrine biology, such as its movements, population turnover, food and nesting habits. Many of the tables and figures have been revised and brought up to date so that this volume, like its predecessor, is once again by far the most detailed and readable reference on this most evocative of birds. Donald Watson's colour paintings, monochrome washes and line drawings, and the original photographs, illustrate the book as before. Cover illustration by Donald Watson
Download and read online Urban Peregrines in PDF and EPUB The Peregrine, the fastest bird in the world, has made a remarkable recovery over the past 30 years. As the species re-establishes itself around the world it is becoming a familiar sight in towns and cities. This beautifully illustrated book is the first in-depth focus on the lives of Peregrines in towns and cities. In words and stunning photographs, Ed Drewitt reveals the latest information on Peregrine behaviour including how they are adapting to, and taking advantage of, the urban environment. The book is also a how-to-guide, with information on finding peregrines, studying their diet, ringing individuals for research, putting up nest boxes and enabling people to learn more about them through public viewing points or web cameras. Ed also discusses what makes a Peregrine urban, their contemporary relationship with people, and helps dispel some myths and reveal some truths about this agile predator.

Download and read online Principles of Ecotoxicology Second Edition in PDF and EPUB Over the past decade ecotoxicology has emerged as a distinct subject of interdisciplinary character. Courses in ecotoxicology reflect this and are taught by specialists in chemistry and biochemistry through to population genetics and ecology. As the first textbook to incorporate all relevant aspects of chemistry, biochemistry, toxicology, physiology, population ecology and population genetics, the first edition of this book proved to be well received across several industries. Featuring fully revised text and new illustrations, Principles of Ecotoxicology identifies the major classes of organic and inorganic pollutants, their properties, release and environmental fate, and transport in air, water and along food chains, before considering the effects that they might have upon individual organisms and ultimately whole ecosystems. This timely second edition of Principles of Ecotoxicology incorporates data collected since the first edition on subjects of current research and media interest such as organochloride pesticides, endocrine disruptors, aquatic toxicity, industrial waste and ecotoxicity testing.
