This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Cooperative breeding in birds occurs when more than two individuals provide care for a single nest. In many species, the additional adults present are offspring from a previous year who have delayed dispersal, and provision young who are non-descendant kin. Delaying dispersal and age of first breeding can influence the demography and fitness of individuals, but the fitness and demographic consequences of helping behavior are poorly understood. Using long-term data (1972-2004), I examined the demographic and fitness consequences of helping behavior in acorn woodpeckers Melanerpes formicivorus. Using a multi-state capture-mark-recapture framework, I found that the apparent survival of breeders was higher than helpers, and the survival of males was higher than females. Juveniles were much more likely to become helpers rather than breeders following fledging, and helpers were more likely to remain helpers rather than becoming a breeder. Both survival and transition rates varied annually and were positively influenced by the acorn crop. For fitness estimation, I focused only on reproductive females who were banded as juveniles. Although helpers began reproduction significantly later and lived significantly longer than breeders, there was no significant difference in lifetime reproductive success or individual fitness between the two groups. However, birds that successfully bred at age 1 without helping had a significantly higher fitness than those who helped and successfully bred at age 2 or older. My results suggest that delayed dispersal and reproduction in the acorn woodpecker lead to a loss of fitness when conditions are favorable for successful reproduction. However, if constraints in the environment prevent an individual from breeding at age 1, helping is a viable option until reproduction is possible.

This book was released on 2020-03-31 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the acorn woodpecker was observed and described by Spanish explorers, its behavior--particularly the unique habit of caching acorns in specialized storage trees or granaries--has impressed observers. Acorn woodpeckers are also one of the few temperate zone species in which young are reared communally in family groups. This demographic study investigates the complexities of acorn storage and group living in acorn woodpeckers at Hastings Reservation in central coastal California. It is one of the most thorough studies of any avian social system to date.

Available in PDF, EPUB and Kindle. Book excerpt: Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

Available in PDF, EPUB and Kindle. Book excerpt: Darwin famously described special difficulties in explaining social evolution in insects. More than a century later, the evolution of sociality - defined broadly as cooperative group living - remains one of the most intriguing problems in biology. Providing a unique perspective on the study of social evolution, this volume synthesizes the features of animal social life across the principle taxonomic groups in which sociality has evolved. The chapters explore sociality in a range of species, from ants to primates, highlighting key natural and life history data and providing a comparative view across animal societies. In establishing a single framework for a common, trait-based approach towards social synthesis, this volume will enable graduate students and investigators new to the field to systematically compare taxonomic groups and reinvigorate comparative approaches to studying animal social evolution.
