An Introduction to Behavioural Ecology


Cuckoo: Cheating by Nature

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 br br 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 br br 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 i Cuckoo i is a lyrical and scientifically satisfying exploration of one of nature s most astonishing and beautiful adaptations


Cuckoos, Cowbirds and Other Cheats

br 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 br 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 br 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 br

Dunnock Behaviour and Social Evolution

At first sight just a small brown bird the dunnock s unobtrusive appearance belies its extraordinary behavior and mating patterns This book gives a full account of the mating systems of the dunnock or hedge sparrow Prunella modularis which include pairs a male with two females two males with one female and several males with several females Detailed observations elegant field experiments and DNA fingerprinting are combined to show how this variable social organization arises from selfish individuals competing to maximize their own reproductive success Further experiments reveal how the cuckoo may thwart the dunnock s parental efforts David Quinn s exquisite drawings provide a visual summary of the bird s behavior All students of ecology evolution and animal behavior will want to be familiar with this work which addresses the wider issues of the influence of ecology on mating systems and the evolutionary significance of conflict within and between species This is the third volume in the Oxford Series in Ecology and Evolution and the first in this series to address behavioral ecology br


Behavioural Ecology: An Evolutionary Approach

Intended for graduate and upper level undergraduate courses in behavioural ecology where students are already familiar with the basic ideas this book continues to define the subject A completely new set of contributions has been brought together once more to take account of the many exciting new developments in the field Each chapter presents a balanced view of the subject integrating a clear exposition of the theory with a critical discussion of how predictions have been tested by experiments and comparative studies In addition the book points to unreconciled issues and possible future developments Edited by two of the most highly regarded experts in the field this new volume contains contributions from an international authorship and continues the tradition of clarity and accessibility established by the three previous editions br br The latest edition of a classic in behavioural ecology br br Divided into three sections Mechanisms and Individual Behaviour From Individual Behaviour to Social Systems and Life Histories Phylogenies and Populations br br Contributions from the world s leading researchers
