YOKEL, Department of Biological Sciences, University of California, Santa Barbara, Santa Barbara, California 93106 PREFACE If it is still true that more than 80% of the ornithologists in North America are primarily interested or engaged in ecological studies on birds (J. R. King and W. J. Bock, Final Report of the Workshop on a National Plan For Ornithology, 1978), then Volume 3 of Current Orni thology is preadapted for their consideration. All but one article in this volume are somehow concerned with the ecological aspects of the bi ology of birds. Variation in the scope of topical coverage is relatively broad, and includes conservation, reproduction, behavior, community structure, and evolutionary ecology. Three reviews concern the pervasive effects of man and industry on various bird populations of the world. Risebrough provides a de tailed description of the relationships between pesticides and bird pop ulations. Morrison ass es ses aspects of bird population numbers as in dicators of environmental change, and Temple outlines current research on endangered species. The broad spectrum of reproductive ecology of birds is variously treated in this volume. Jehl and Murray explore sexual selection and some of the resulting complexities in the evolution of sexual size di morphism, primarily in shorebirds. Lawton and Lawton are concerned with the relationships between social behavior and breeding systems in which variation is found in the age at which reproduction is first undertaken. Oring examines the wide-ranging variation in polyandrous breeding systems in birds, while Rohwer is concerned with adoption versus infanticide in birds, and their relationships to reproductive fit ness. vii viii PREFACE Payne examines the significance of bird song to certain aspects of avian systematics, and Rothstein, Yokel, and Fleischer provide detailed descriptions of several aspects of the behavioral ecology of Brown headed Cowbirds. Willson looks at some of the relationships between bird and plant communities to be found at temperate latitudes, and Greenberg examines the degrees of competition that may influence dis tribution and abundance of high-latitude migrants on their wintering grounds or in the nonbreeding season. The Editorial Board and I greatly appreciate suggestions and rec ommendations that have been received over the past four years from the ornithological community for topics and authors of current interest and significance; a number of them appear in this volume.
