Book Description
Among birds, shorebirds provide some of the more unique opportunities to examine basic problems in behavior, ecology, and evolution. This is in large measure due to the diversity, both behaviorally and ecologically, of a group closely related taxonomically and distributed throughout the world. The overall aim of these two volumes is to provide a representative selection of current research being conducted on shorebird behavior and ecology. Traditionally, marine birds have included those species that breed in large colonies on offshore islands along coasts (see Volume 4 of this series). Although shorebirds have generally not been considered within this group, the fact that almost 40% of the species breed along coasts and more than 60% often or always spend the nonbreeding season in coastal habitats more than justifies their inclusion as marine birds (at least those species that totally or partially depend upon the marine environment). Their inclusion markedly increases species diversity in marine birds since shorebirds add about 217 species to the 280 that are traditionally thought of as marine.

Book Description
The Extended Specimen highlights the research potential for ornithological specimens, and is meant to encourage ornithologists poised to initiate a renaissance in collections-based ornithological research. Contributors illustrate how collections and specimens are used in novel ways by adopting emerging new technologies and analytical techniques. Case studies use museum specimens and emerging and non-traditional types of specimens, which are developing new methods for making biological collections more accessible and "usable" for ornithological researchers. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series documents the power of ornithological collections to address key research questions of global importance.

Book Description
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.
