Download or read book Field Guide to the Songbirds of South America written by Robert S. Ridgely and published by University of Texas Press. This book was released on 2009-06-01 with total page 761 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the publication of the landmark volumes The Birds of South America: The Oscine Passerines and The Birds of South America: The Suboscine Passerines, Robert S. Ridgely and Guy Tudor established themselves as the leading authorities on the songbirds of South America. Reviewers hailed the volumes as the essential reference works for professional ornithologists and avocational birders alike, and they remain the only volumes that provide full scientific coverage of the continent's passerines. Recognizing the need for a more compact guide that birders can take into the field, Ridgely and Tudor have now extracted and updated the essential identification information from The Birds of South America to create the Field Guide to the Songbirds of South America. This definitive guide is filled with indispensable features: 121 color plates that present Guy Tudor's magnificently detailed paintings of more than 1,500 species of songbirds, including more than 400 that were not illustrated in BOSA 160 additional color illustrations of subspecies and females Extensively updated color range maps for all of the species in the field guide, prepared by Robert S. Ridgely with technical assistance from Maria Allen and Terry Clarke, appear opposite the plates for each bird family Robert S. Ridgely's authoritative accounts of nearly 2,000 species that cover each bird's abundance, habitat, and range; elevational preference; taxonomic or nomenclatural changes; plumage description; general behavior and voice; and range beyond South America, if applicable

Download or read book On the Origin of Species Through Heteropatric Differentiation written by Kevin Winker and published by Univ of California Press. This book was released on 2010-11 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differentiation and speciation without extended isolation appear to be common among migratory animals. Historical oversight of this is probably due to temporal distortion in distribution maps and a tendency to consider that lineages had different historical traits, such as being sedentary or much less mobile. Mobility among cyclic migrants makes population isolation difficult, and diminished levels of intraspecific differentiation occur in avian migrants (I term this "Montgomery's rule"). Nevertheless, many lineages have differentiated despite increased mobility and a high propensity for gene flow, conditions that speciation theory has not addressed adequately. Populations of seasonal migrants usually occur in allopatry and sympatry during a migratory cycle, and this distributional pattern (heteropatry) is the focus of a model empirically developed to explain differentiation in migratory lineages. Divergence arises through disruptive selection from resource competition and heterogeneously distributed cyclic resources. Heteropatric speciation is a type of ecological speciation in which reproductive isolation increases between populations as a byproduct of adaptation to different environments that enhances breeding allopatry and allochrony despite degrees of sympatry that occur during the nonbreeding period in migration cycles. Mating or pair bonding in nonbreeding areas is rare. Patterns such as leapfrog migration and limited morphological divergence suggest that differentiation is driven by these ecological factors rather than by sexual selection or nontemporal changes in the resource base itself, although the additional presence of either of the latter would have additive divergent effects. Migratory lineages provide a largely neglected series of natural experiments in speciation in which to test predictions stemming from this model and others focusing on ecological speciation --

Download or read book The Extended Specimen written by Michael S. Webster and published by CRC Press. This book was released on 2017-07-20 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Neotropical Birds of Prey written by David Whitacre and published by Cornell University Press. This book was released on 2013-05-15 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, surprisingly little has been known about the biology and behavior of tropical forest raptors, including such basic aspects as diets, breeding biology, habitat requirements, and population ecology, information critical to the development of conservation efforts. The Peregrine Fund conducted a significant eight-year-long research program on the raptor species, including owls, in Tikal National Park in Guatemala to learn more about Neotropical birds of prey. Impressive and unprecedented in scale, this pioneering research also involved the development of new methods for detecting, enumerating, and studying these magnificent but often elusive birds in their forest home. Beautifully illustrated with photographs of previously little-known species, the resulting book is the most important single source for information on the lowland tropical forest raptor species found in Central America.Neotropical Birds of Prey covers twenty specific species in depth, including the Ornate Hawk-Eagle, the Barred Forest-Falcon, the Bat Falcon, and the Mexican Wood Owl, offering thorough synopses of all current knowledge regarding breeding biology and behavior, diet, habitat use, and spatial needs. Contributors to this landmark work also show how the populations fit together as a community with overlapping habitat and prey needs that can put them in competition with reptiles and mammalian carnivores as well, yet differ from one another in their nesting or feeding behaviors and population dynamics. The work's substantive original data offer interesting comparisons between tropical and temperate zone species, and provide a basis for establishing conservation measures based on firsthand research. Making available for the first time new data on the biology, ecology, behavior, and conservation of the majestic owls and raptors of the New World tropics, this book will appeal to a wide ornithological readership, especially the many raptor enthusiasts around the world.

Download or read book Nature s Music written by Peter R. Marler and published by Elsevier. This book was released on 2004-10-05 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The voices of birds have always been a source of fascination. Nature's Music brings together some of the world's experts on birdsong, to review the advances that have taken place in our understanding of how and why birds sing, what their songs and calls mean, and how they have evolved. All contributors have strived to speak, not only to fellow experts, but also to the general reader. The result is a book of readable science, richly illustrated with recordings and pictures of the sounds of birds. Bird song is much more than just one behaviour of a single, particular group of organisms. It is a model for the study of a wide variety of animal behaviour systems, ecological, evolutionary and neurobiological. Bird song sits at the intersection of breeding, social and cognitive behaviour and ecology. As such interest in this book will extend far beyond the purely ornithological - to behavioural ecologists psychologists and neurobiologists of all kinds.* The scoop on local dialects in birdsong* How birdsongs are used for fighting and flirting* The writers are all international authorities on their subject

Download or read book The Great Eagles written by Michael O'Neal Campbell and published by CRC Press. This book was released on 2022-05-19 with total page 1666 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the current literature and knowledge on the evolution and ecology of all the birds named as eagles, with particular emphasis on the larger species. It also examines the past and current relations between eagles and people, including habitat change and conservation issues. Eagle ecologies and conservation are currently seriously impacted by human activities such as industrialization, urbanization, pollution, deforestation and hunting. Some eagle species have consequently experienced extreme population changes. There are, however, some positive developments. Eagles have a strong, historic bond with human civilization, due to their status as the world’s most charismatic birds. Conservation policies have also been successful in repopulating some ecosystems with breeding eagles. Therefore, despite the complexity of this relationship, there may yet be hope for this unique species group, frequently rated as the kings of birds, and symbolic of human power, ambition, royalty, nationality, and even concepts of God. It is hoped that this book will contribute to the further understanding of these unique and fantastic birds.

Download or read book Birds New to Science written by David Brewer and published by Bloomsbury Publishing. This book was released on 2018-01-26 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of the discovery of nearly 300 bird species new to science since 1960. Amazing as it might sound, ornithologists are still discovering several bird species each year that are completely new to science. These aren't all obscure brown birds on tiny islands – witness the bizarre Bare-faced Bulbul from Laos (2009), spectacular Araripe Manakin from Brazil (1998), or gaudy Bugun Liocichla from north-east India (2006). Birds New to Science documents more than half a century of these remarkable discoveries, covering around 300 species. Each account includes the story of discovery, a brief description of the bird (many with accompanying colour photographs), and details of what is known about its biology, range and conservation status. Written in an engaging style, this is a rich reference to an incredible era of adventure in ornithology.
