Available in PDF, EPUB and Kindle. Book excerpt: "This is an amazingly compact, up-to-date history of the politics and biological research of the California Condor. It will be invaluable for biology students who want to review a case study of an endangered species and for environmental planners considering the highly political nature of rare-species conservation."—Allen Fish, Director, Golden Gate Raptor Observatory "As one of the most visible, dramatic, and controversial examples of intensive conservation management in modern times, the California Condor makes a good story. The Snyders' work is exemplary. This is a solid introduction to the subject and an excellent contribution to the press's natural history series."—Walter Koenig, Hastings Natural History Reservation, University of California

Available in PDF, EPUB and Kindle. Book excerpt: Studies in numerous animal taxa demonstrate that early rearing experience has a profound influence on the development of later adaptive behavior. This has implications for endangered species management, particularly when animals are reared in captivity for reintroduction or in cases in which species managers play an active role in managing animals at the individual or population levels. The California condor (Gymnogyps californianus) is a critically endangered New World vulture that was subject to a period of extinction in the wild followed by ongoing reintroduction in portions of its native range. Though the reintroduced population in southern California is largely adapting well, several obstacles to viability remain that are primarily anthropogenic in nature. The purpose of this study was to quantitatively assess nesting behavior of free-flying California condors in the southern California population to determine whether differences in parental care and nestling behavior are attributable to parental rearing conditions and experience. Hierarchical generalized linear modeling was used to analyze parent and chick activity budget data. Differences among condors were not detected in attendance patterns across either the egg or chick phases of nesting. Variation was not detected among chicks in proportion of time spent active and inactive during the early nestling phase. Variations among older nestlings in the proportion of time spent inactive were observed, with associations detected between inactivity, pair, visibility and season. The proportion of time that parents interacted with nestlings varied from nest to nest, with associations detected between interaction, visibility and season. Finally, potential pair-level variation in the propensity to bring microtrash to the nest was observed. It is concluded that while visibility is often overlooked in behavioral analyses, it is methodologically important to account for this variable in analyses of condor nestling behavior. Further, while some pair-level variation in allocation of care to nestlings is apparent, this appears to be a function of factors not related to individual developmental differences.

Available in PDF, EPUB and Kindle. Book excerpt: The California condor is the largest bird in North America. Scientists have found condor fossils that are nearly 100,000 years old. As more people settled in the American west, however, condors lost much of their habitat to human development. By 1982, fewer than 25 California condors lived in the wild. Read this book to find out more about California condors, how they came close to extinction, and what people are doing do help make sure condors stay on the road to recovery.

Available in PDF, EPUB and Kindle. Book excerpt: A key way that behavioral ecologists develop general theories of animal behavior is by studying one species or a closely related group of species--''model systems''--over a long period. This book brings together some of the field's most respected researchers to describe why they chose their systems, how they integrate theoretical, conceptual, and empirical work, lessons for the practice of the discipline, and potential avenues of future research. Their model systems encompass a wide range of animals and behavioral issues, from dung flies to sticklebacks, dolphins to African wild dogs, from foraging to aggression, territoriality to reproductive suppression. Model Systems in Behavioral Ecology offers an unprecedented ''systems'' focus and revealing insights into the confluence of personal curiosity and scientific inquiry. It will be an invaluable text for behavioral ecology courses and a helpful overview--and a preview of coming developments--for advanced researchers. The twenty-five chapters are divided into four sections: insects and arachnids, amphibians and reptiles, birds, and mammals. In addition to the editor, the contributors include Geoff A. Parker, Thomas D. Seeley, Naomi Pierce, Kern Reeve, Gerald S. Wilkinson, Bert Hölldobler and Flavio Roces, George W. Uetz, Michael J. Ryan and Gil Rosenthal, Judy Stamps, H.
