Based on the approach laid out in the 1950s by Nobel laureate Nikolaas Tinbergen, this book looks at animal communication from the four perspectives of mechanisms, ontogeny, function, and phylogeny.

How can we explain the peacock's beautiful tail decorations, or the wonderful song of the nightingale? Why are some smells nice and others nasty? How do animals signal their intentions and qualities to potential partners? How do offspring tell parents about their needs? Are signals tuned to the environment, and to the mental abilities of receivers? Essential for understanding how animals cope with their ecological and social environment, the study of animal signals is one of the most active research areas in evolutionary biology. Understanding the signalling systems of nature has wide-ranging relevance including biological conservation and human communication. Written by international scientists, this is a comprehensive overview of the fascinating diversity of animal signals and signalling functions. Combining reviews and research, the book is aimed at both students and professional scientists.

This book explores the strikingly similar ways in which information is encoded in nonverbal man-made signals (e.g., traffic lights and tornado sirens) and animal-evolved signals (e.g., color patterns and vocalizations). The book also considers some coding principles for reducing certain unwanted redundancies and explains how desirable redundancies enhance communication reliability. Jack Hailman believes this work pioneers several aspects of analyzing human and animal communication. The book is the first to survey man-made signals as a class. It is also the first to compare such human-devised systems with signaling in animals by showing the highly similar ways in which the two encode information. A third innovation is generalizing principles of quantitative information theory to apply to a broad range of signaling systems. Finally, another first is distinguishing among types of redundancy and their separation into unwanted and desirable categories. This remarkably novel book will be of interest to a wide readership. Appealing not only to specialists in semiotics, animal behavior, psychology, and allied fields but also to general readers, it serves as an introduction to animal signaling and to an important class of human communication.

In creatures as different as crickets and scorpions, mole rats and elephants, there exists an overlooked channel of communication: signals transmitted as vibrations through a solid substrate. Peggy Hill summarizes a generation of groundbreaking work by scientists around the world on this long understudied form of animal communication. Beginning in the 1970s, Hill explains, powerful computers and listening devices allowed scientists to record and interpret vibrational signals. Whether the medium is the sunbaked savannah or the stem of a plant, vibrations can be passed along from an animal to a potential mate, or intercepted by a predator on the prowl. Vibration appears to be an ancient means of communication, widespread in both invertebrate and vertebrate taxa. Hill synthesizes in this book a flowering of research, field studies documenting vibrational signals in the wild, and the laboratory experiments that answered such questions as what adaptations allowed animals to send and receive signals, how they use signals in different contexts, and how vibration as a channel might have evolved. Vibrational Communication in Animals promises to become a foundational text for the next generation of researchers putting an ear to the ground.

In this book, W. John Smith enlarges ethology's perspective on communication and takes it in new directions. Traditionally, ethological analysis has focused on the motivational states of displaying animals: What makes the bird sing, the cat lash its tail, the bee dance? The Behavior of Communicating emphasizes messages. It seeks to answer questions about the information shared by animals through their displays: What information is made available to a bird by its neighbor's song, to a cat by its opponent's gesture, to a bee by its hivemate's dancing? What information is extracted from sources contextual to these displays? How are the responses to displays adaptive for recipients and senders? What evolutionary processes and constraints underlie observed patterns of animal communication? Smith's approach is deeply rooted in the ethological tradition of naturalistic observations. Detailed analysis of observed displays and display repertoires illuminates the theoretical discussion that forms the core of the book. A taxonomy and interpretative analysis of messages made available through formalized display behavior are also developed. Smith shows that virtually all subhuman animal displays may be interpreted as transmitting messages about the communicator--not the environment--and, more specifically, that messages indicate the kinds of behavior the displaying animal may choose to perform. The most widespread behavioral messages are surprisingly general, even banal, in character; yet they make public information that is not readily available from other sources and that would otherwise be essentially private to the communicator. Taken along with information from sources contextual to the displays, the messages made available may permit responses that are markedly specific. By taking advantage of contextual specificity, a species expands the capacity of its display behavior to be functional in numerous and diverse circumstances. After developing the concept of messages and discussing their forms, the responses made to them, and the functions engendered, Smith turns to the evolution of display behavior--the ways in which acts become specialized for communication and the nature of the evolutionary constraints affecting the ultimate forms of displays. He revises the traditional ethological concept of displays, and in a final chapter develops the further concept of formalized interactions. Here he extends the discussion to formal patterns of behavior that, unlike displays, are beyond the capabilities of individual performers. Human nonverbal communication, which is considered from time to time throughout the book, provides the richest examples of communication flexibly structured at this level of complexity.
