The aim of Advances in the Study of Behavior remains as it has been since the series began: to serve the increasing number of scientists who are engaged in the study of animal behavior by presenting their theoretical ideas and research to their colleagues and to those in neighboring fields. We hope that the series will continue its "contribution to the development of the field," as its intended role was phrased in the Preface to the first volume in 1965. Since that time, traditional areas of animal behavior have achieved new vigor by the links they have formed with related fields and by the closer relationship that now exists between those studying animal and human subjects.
Advances in the Study of Behavior, Volume 31 continues to serve scientists across a wide spectrum of disciplines. Focusing on new theories and research developments with respect to behavioral ecology, evolutionary biology, and comparative psychology, these volumes foster cooperation and communications in these dense fields.

The aim of Advances in the Study of Behavior is to serve scientists engaged in the study of animal behavior, including psychologists, neuroscientists, biologists, ethologists, pharmacologists, endocrinologists, ecologists, and geneticists. Articles in the series present critical reviews of significant research programs with theoretical syntheses, reformulation of persistent problems, and/or highlighting new and exciting research concepts. Volume 34 is purely eclectic and illustrates the breadth of behavior research. Contents include sexual conflict among insects, the evolution of sexual cannibalism, odor processing and activity patterns in honeybees, hormone secretion in vertebrates, bird song organization, food transfer in primates, game theory approaches to mutualism, as well as neural mechanisms of learning and memory and how these change during infant development.

For at least 30 years, there have been close parallels between studies of birdsong development and those of the development of human language. Both song and language require species-specific stimulation at a sensitive period in development and subsequent practice through subsong and plastic song in birds and babbling in infant humans leading to the development of characteristic vocalisations for each species. This book illustrates how social interactions during development can shape vocal learning and extend the sensitive period beyond infancy and how social companions can induce flexibility even into adulthood. Social companions in a wide range of species including birds and humans but also cetaceans and nonhuman primates play important roles in shaping vocal production as well as the comprehension and appropriate usage of vocal communication. This book will be required reading for students and researchers interested in animal and human communication and its development.
