Cuckoos, Cowbirds and Other Cheats available in PDF, EPUB and Kindle. In this fascinating new book, Nick Davies describes the natural histories of these brood parasites and examines many of the exciting questions they raise about the evolution of cheating and the arms race between parasites and their prey. Brood parasites fill their armory with adaptations including exquisite egg mimicry, rapid laying, ejection of host eggs, murder of host young, chick mimicry and manipulative begging behavior: ploys shown by recent research to have evolved in response to host defense behavior or through competition among the parasites themselves. While many host species appear defenseless, accepting parasite eggs quite unlike their own, many are more discriminating against odd-looking eggs and some have evolved the ability to discriminate against odd-looking chicks as well. How is this arms race conducted? Will defenseless hosts develop defenses in time, or are there constraints which limit the evolution and perfection of host defenses? And why are so few species obliged only to lay eggs in host nests? Have host defenses limited the success of brood parasitism, or is it in fact much more common than we suspect, but occurring mainly when birds parasitize the nest of their own kind? All of these puzzles are examined in descriptions of the natural history of each of the groups of parasites in turn.Here is a book with wide appeal, both to amateur naturalists fascinated by this most singular and macabre of behaviors and by ornithologists and ecologists interested in the evolution of ecology and behavior. The story takes us from the classic field work earlier this century by pioneer ornithologists such as Edgar Chance, Stuart Baker, Herbert Friedmann and others, through to the recent experimental field work and molecular techniques of today's leading scientists. We visit brood parasites in Europe, Asia, Japan, Africa, Australasia, and North and South America, to look at some of the worlds most interesting birds and some of biology's most interesting questions, many of which still beg answers from ornithologists in the future.Brilliant illustrations by David Quinn illuminate the species discussed, showing many behaviors never before illustrated and conveying the thrill of watching these astonishing birds in the wild.

This book was released on 2015-04-07. Cuckoo available in PDF, EPUB and Kindle. 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.

This book was released on 2015-01-01. Cuckoo available in PDF, EPUB and Kindle. Beloved as the herald of spring, cuckoos have held a place in our affections for centuries. The oldest song in English celebrates the cuckoo's arrival, telling us that 'Sumer is icumen in'. But for many other birds the cuckoo is a signal of doom, for it is Nature's most notorious cheat. Cuckoos across the world have evolved extraordinary tricks to manipulate other species into raising their young. How do they get away with it?In this enormously engaging book, naturalist and scientist Nick Davies reveals how cuckoos trick their hosts. Using shrewd detective skills and field experiments, he uncovers an evolutionary arms race, in which hosts evolve better defences against cuckoos and cuckoos, in turn, evolve novel forms of trickery. This is a fascinating corner of Darwin's 'entangled bank', where creatures are continually evolving to keep up with changes in their rivals.Lively field drawings by James McCallum, and remarkable photographs, show cuckoos in action: from the female cuckoo laying her beautifully disguised egg, to the cuckoo chick ejecting the host's eggs and young from the nest to ensure it gets the full attention of its foster parents.Cuckoo offers a new insight not only into the secret lives of these extraordinary birds, but also into how cheating evolves and thrives in the natural world.

Download and read online ebook Cheats and Deceits write by Martin Stevens. This book was released on 2016-02-04. Cheats and Deceits available in PDF, EPUB and Kindle. In nature, trickery and deception are widespread. Animals and plants mimic other objects or species in the environment for protection, trick other species into rearing their young, lure prey to their death, and deceive potential mates for reproduction. Cuckoos lay eggs carefully matched to their host's own clutch. Harmless butterflies mimic the wing patterning of a poisonous butterfly to avoid being eaten. The deep-sea angler fish hangs a glowing, fleshy lure in front of its mouth to draw the attention of potential prey, while some male fish alter their appearance to look like females in order to sneak past rivals in mating. Some orchids develop the smell of female insects in order to attract pollinators, while carnivorous plants lure insects to their death with colourful displays. In this book, Martin Stevens describes the remarkable range of such adaptations in nature, and considers how they have evolved, and become increasingly perfected as part of an arms race between predator and prey or host and parasite. He explores the work of naturalists and biologists from Alfred Russel Wallace to current research, showing how scientists find ways of testing the impact of particular behaviours and colourings on the animals it is meant to fool, as opposed to our human perceptions. Drawing on a wide range of examples, Stevens considers what deception tells us about the process of evolution and adaptation.
