Download or read book Behavioral Ecology of Neotropical Birds written by Juan Carlos Reboreda and published by Springer. This book was released on 2019-04-24 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers central aspects of behavioral ecology, including sexual selection, social and genetic mating systems, cooperative breeding, brood parasitism, brood reduction, migration, personalities and communication. Over the past several years, Neotropical bird species from temperate to tropical latitudes of South America have been extensively studied, yielding valuable insights into the evolutionary mechanisms that drive their behavioral traits. In this book, international experts provide a general overview of main behavioral aspects. They also present the main findings of their work, including experimental approaches to testing the most accepted behavioral theory in their model systems. In closing, they propose new theoretical frameworks and future research directions. As such, the book provides a comprehensive and updated guide for all researchers, students and professionals whose work involves the study and management of birds across the Neotropical region.
Download or read book The Birds of South America written by Robert S. Ridgely and published by University of Texas Press. This book was released on 1989 with total page 956 pages. Available in PDF, EPUB and Kindle. Book excerpt: A land of incredible natural resources, the South American continent is rich in plant and animal species. Among birds alone, over 3,100 species are either resident or migrant. Birds are some of South America's treasures and also one of its most endangered resources. Hence the need for a descriptive record of South American birds that will serve both professional and amateur bird students and encourage conservation of these magnificent species. Although South American birds elicit much popular and scientific interest, they have never been completely or satisfactorily described and cataloged in a single, published source. The Birds of South America, projected to be a four-volume work, thus fills a critical void. Starting from a museum approach, the authors have examined specimens of each subspecies, comparing them visually and trying to discern the patterns in their plumage variation, both intra- and inter-specifically. They take a new look at bird systematics, reassessing relationships in light of new information. Perhaps most important, they combine this review and analysis with extensive field observations to give an accurate, incisive portrait of the birds in nature. At a time when rapid development is devastating millions of acres of tropical habitat in South America, this record of an endangered resource becomes crucial. If the birds and other plants and animals of South America are to be saved, they must first be known and appreciated. The Birds of South America is a major step in that direction. Volume II includes the Ovenbirds and Woodcreepers, Antbirds, Gnatcatchers, and Tapaculos; Tyrant Flycatchers; and Manakins and Cotingas. The remaining volumes of The Birds of South America will be: Volume III: The Nonpasserines (Landbirds) Volume IV: The Nonpasserines (Waterbirds) No release date has been set for the remaining volumes.

Download or read book A Guide to the Birds of Panama written by Robert S. Ridgely and published by Princeton University Press. This book was released on 1989 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first paperback version of the second edition of the popular A Guide to the Birds of Panama. In the second edition, published in 1989, the authors expanded information on the birds of Costa Rica, Nicaragua, and Honduras: approximately 200 new species were added to the material in the 1976 edition. Over 300 additional species, some of them Panamanian, were illustrated. Sixteen new plates were added, and three of the original plates were replaced by improved versions. Throughout the book changes were made to accommodate the explosion in knowledge of the birds of Panama and nearby areas and of neotropical birds in general. The basic sequence and systematics of the AOU 1983 Check-list were adopted. Also included in the revised edition was expanded and updated information on birdfinding in Panama, prepared with the assistance of two of Panama's best resident birders. The book also contains a special section outlining developments in Panama ornithology and conservation.

Download or read book Moult and Ageing of European Passerines written by Lukas Jenni and published by A&C Black. This book was released on 2011-11-21 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The moult strategies of birds are not only of importance in their impact on a species' ecology and energetics, but as a valuable tool for anyone studying the migration and population dynamics of bird species. A proper understanding of how feathers are replaced, and the precise differences in appearance of the various feather generations, can allow ringers, scientists and the keen birdwatcher to age first-year and adult birds and to detect the moult strategy of the bird in question. Lukas Jenni and Raffael Winkler have combined these themes and produced a book which will be valuable both to the professional ornithologist and the bird ringer. The first part gives an up to date summary of the moult strategies and moult sequences of European passerines and discusses the ecological consequences of moult. Throughout the book, the authors draw on the enormous amount of data on moult collected by them over 15 years of study which, combined with data from the literature, allow them to present a new synthesis of the subject. The second part of the book is of particular value to ringers. Following a general introduction to ageing, detailed moult profiles are given for 58 species of European passerines representing all the major moult strategies, backed up with useful summary statistics, schematic diagrams of the extent of moult and indications of the variation within each species. For the first time, the extent of partial and suspended moults is presented in detail. The crowning feature of this book is the 480 plus full colour photographs of extended wings which show the entire range of moult patterns and of plumage ageing criteria. An appendix gives supplementary information on ageing birds by the degree of pneumatization of the skull.

Download or read book The Avian Migrant written by John H. Rappole and published by Columbia University Press. This book was released on 2013-06-11 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of migration, regardless of the distance involved, is to exploit two or more environments suitable for survival or reproduction over time, usually on a seasonal basis. Yet individual organisms can practice the phenomenon differently, and birds deploy unique patterns of movement over particular segments of time. Incorporating the latest research on bird migration, this concise, critical assessment offers contemporary readers a firm grasp of what defines an avian migrant, how the organism came to be, what is known about its behavior, and how we can resolve its enduring mysteries. John H. Rappole's sophisticated survey of field data clarifies key ecological, biological, physiological, navigational, and evolutionary concerns. He begins with the very first migrants, who traded a home environment of greater stability for one of greater seasonality, and uses the structure of the annual cycle to examine the difference between migratory birds and their resident counterparts. He ultimately connects these differences to evolutionary milestones that have shaped a migrant lifestyle through natural selection. Rather than catalogue and describe various aspects of bird migration, Rappole considers how the avian migrant fits within a larger ecological frame, enabling a richer understanding of the phenomenon and its critical role in sustaining a hospitable and productive environment. Rappole concludes with a focus on population biology and conservation across time periods, considering the link between bird migration and the spread of disease among birds and humans, and the effects of global warming on migrant breeding ranges, reaction norms, and macroecology.
