Avian Ancestors: A Review of the Phylogenetic Relationships of the Theropods Unenlagiidae, Microraptoria, Anchiornis and Scansoriopterygidae (SpringerBriefs in Earth System Sciences)
by Fernando E. Novas Federico AgnolinAlthough consensus exists among researchers that birds evolved from coelurosaurian theropods, paleontologists still debate the identification of the group of coelurosaurians that most closely approaches the common ancestor of birds. The last 20 years witnessed the discovery of a wide array of avian-like theropods that has considerably amplified the anatomical disparity among deinonychosaurians, some of which resemble Archaeopteryx more than Deinonychus. Among these newly discovered theropods that show remarkable bird-like characteristics are the four-winged theropods Microraptor and Anchiornis, and the unenlagiids Unenlagia, Buitreraptor, and Rahonavis. A bizarre group of minute-sized coelurosaurs, the Scansoriopterygidae, also exhibits some avian similarities that lead some authors to interpret them as more closely related to birds than other dinosaurs. With the aim to explore the phylogenetic relationships of these coelurosaurians and birds, we merged recently published integrative databases, resulting in significant changes in the topological distribution of taxa within Paraves. We present evidence that Dromaeosauridae, Microraptoria, Unenlagiidae, and Anchiornis + Xiaotingia form successive sister taxa of Aves, and that the Scansoriopterygidae are basal coelurosaurians not closely related to birds. The implications in the evolutionary sequence of anatomical characters leading to birds, including the origin of flight, are also considered in light of this new phylogenetic hypothesis.
Avian Architecture: How Birds Design, Engineer, and Build
by Peter GoodfellowAn illustrated guide to how birds design and build their nestsBirds are the most consistently inventive builders, and their nests set the bar for functional design in nature. Avian Architecture describes how birds design, engineer, and build their nests, deconstructing all types of nests found around the world using architectural blueprints and detailed descriptions of the construction processes and engineering techniques birds use. This spectacularly illustrated book features 300 full-color images and more than 35 case studies that profile key species worldwide. Each chapter covers a different type of nest, from tunnel nests and mound nests to floating nests, hanging nests, woven nests, and even multiple-nest avian cities. Other kinds of avian construction—such as bowers and harvest wells—are also featured.Avian Architecture includes intricate step-by-step sequences, visual spreads on nest-building materials and methods, and insightful commentary by a leading expert.Illustrates how birds around the world design, engineer, and build their nestsFeatures architectural blueprints, step-by-step sequences, visual spreads on nest-building materials and methods, and expert commentaryIncludes 300 full-color imagesCovers more than 100 bird species worldwide
Avian Brood Parasitism: Behaviour, Ecology, Evolution And Coevolution (Fascinating Life Sciences)
by Manuel SolerBrood parasitism has become one of the most flourishing areas of research in evolutionary ecology and one of the best model systems for investigating coevolution. This subject has undergone remarkable advances during the last two decades, but has not been covered by any book in the 21st century. This book offers a comprehensive and up-to-date overview of the fascinating field of avian brood parasitism. The topics covered include conspecific brood parasitism; evolution and phylogenetic history of avian brood parasites; parasitic behaviour used by brood parasites; adaptations and counter-adaptations of brood parasites and their hosts at every stage of the breeding cycle (before laying, egg, chick and fledgling stages); factors affecting the evolution of host defences and parasitic attacks; the role of phenotypic plasticity in host defences; mechanisms driving egg recognition and rejection; evolution of nest sharing or nest killing by brood parasite chicks; begging behaviour in parasitized nests and food delivery by host adults; and recognition of conspecifics by juvenile brood parasites. This volume provides a comprehensive reference resource for readers and researchers with an interest in birds, behaviour and evolution, as well as a source of hypotheses and predictions for future investigations into this dynamic subject.
Avian Cellular Immunology
by JagdevM. SharmaKnowledge regarding avian cellular immunity has expanded rapidly within the last few years and new information continues to accumulate. It is now a well-established fact that cell-mediated immunity plays a major role in the defense against neoplastic and non-neoplastic diseases in chickens. The principle objective of Avian Cellular Immunology is to compile the latest information available on various aspects of avian cellular immunity. The book contains chapters written by leading experts in the field and covers topics including cell surface markers, T-cell immunity, natural immune functions, the role of macrophages in cellular immune functions, cellular immune suppression and tolerance, cellular immune systems in avian species other than chickens, the role of cellular immunity in neoplastic and non-neoplastic viral diseases, cell-mediated immune mechanisms in bacterial and parasitic infections, and autoimmune disorders.
Avian Cognition
by Susan D. Ten Cate Carel HealyThe cognitive abilities of birds are remarkable: hummingbirds integrate spatial and temporal information about food sources, day-old chicks have a sense of numbers, parrots can make and use tools, and ravens have sophisticated insights in social relationships. This volume describes the full range of avian cognitive abilities, the mechanisms behind such abilities and how they relate to the ecology of the species. Synthesising the latest research in avian cognition, a range of experts in the field provide first-hand insights into experimental procedures, outcomes and theoretical advances, including a discussion of how the findings in birds relate to the cognitive abilities of other species, including humans. The authors cover a range of topics such as spatial cognition, social learning, tool use, perceptual categorization and concept learning, providing the broader context for students and researchers interested in the current state of avian cognition research, its key questions and appropriate experimental approaches.
Avian Ecology in Latin American Cityscapes
by Ian MacGregor-Fors Juan F. Escobar-IbáñezThis book gathers a representative sample of the relevant knowledge related to the ecology, behavior, and conservation of birds in urban Latin America. Latin America is one of the most biodiverse regions of the world, yet it is still understudied. Although it concentrates most of its population in rapidly growing cities under considerable economic, social, and environmental disparity, the study of the effects that urbanization has on biodiversity in Latin America is still insufficient. Among the best-studied wildlife groups, birds have been widely used as bioindicators in urban areas. Going from general to specific information regarding avian communities, populations, behavior, threats, and conservation issues, this book describes the state-of-the-art of avian urban ecology in the region. Such knowledge will hopefully promote the regional consolidation of the field and encourage future mechanistic studies that untangle the recorded patterns in order to have the required information to bridge the gap between evidence-based knowledge and practice in urban systems. Thus, the information included in this document will allow scientists, students, and even decision takers to relate with the current knowledge and gaps related to the topic, providing perspective for future studies and actions.
Avian Genomics in Ecology and Evolution: From the Lab into the Wild
by Robert H. S. KrausBirds catch the public imagination like no other group of animals; in addition, birders are perhaps the largest non-professional naturalist community. Genomics and associated bioinformatics have revolutionised daily life in just a few decades. At the same time, this development has facilitated the application of genomics technology to ecological and evolutionary studies, including biodiversity and conservation at all levels. This book reveals how the exciting toolbox of genomics offers new opportunities in all areas of avian biology. It presents contributions from prominent experts at the intersection of avian biology and genomics, and offers an ideal introduction to the world of genomics for students, biologists and bird enthusiasts alike. The book begins with a historical perspective on how genomic technology was adopted by bird ecology and evolution research groups. This led, as the book explains, to a revised understanding of avian evolution, with exciting consequences for biodiversity research as a whole. Lastly, these impacts are illustrated using seminal examples and the latest discoveries from avian biology laboratories around the world.

They present exciting, cutting-edge new methods that focus both on studying the virus itself and on work with avian hosts, an area greatly lacking in research.
Avian Malaria Parasites and other Haemosporidia
by Gediminas ValkiunasWhen studying the effects of parasites on natural populations, the avian haematozoa fulfills many of the specifications of an ideal model. Featuring a multitude of tables and illustrations, Avian Malaria Parasites and Other Haemosporidia summarizes more than a century of research on bird haemosporidians. For a long time, bird blood parasites served as important models in studying human diseases. Although now largely replaced, the wealth of data and research remain. With chapters addressing life cycles and morphology, pathogenicity, ultrastructure, geographical distribution, and illustrated keys to all known species of the parasites, this book is a masterful assessment of the biology of bird haemosporidian parasites.
Avian Malaria and Related Parasites in the Tropics: Ecology, Evolution and Systematics
by Diego Santiago-Alarcon Alfonso MarzalThe Tropics are home to the greatest biodiversity in the world, but tropical species are at risk due to anthropogenic activities, mainly land use change, habitat loss, invasive species, and pathogens. Over the past 20 years, the avian malaria and related parasites (Order: Haemosporida) systems have received increased attention in the tropical regions from a diverse array of research perspectives. However, to date no attempts have been made to synthesize the available information and to propose new lines of research. This book provides such a synthesis by not only focusing on the antagonistic interactions, but also by providing conceptual chapters on topics going from avian haemosporidians life cycles and study techniques, to chapters addressing current concepts on ecology and evolution. For example, a chapter synthesizing basic biogeography and ecological niche model concepts is presented, followed by one on the island biogeography of avian haemosporidians. Accordingly, researchers and professionals interested in these antagonistic interaction systems will find both an overview of the field with special emphasis on the tropics, and access to the necessary conceptual framework for various topics in ecology, evolution and systematics. Given its conceptual perspective, the book will appeal not only to readers interested in avian haemosporidians, but also to those more generally interested in the ecology, evolution and systematics of host-parasite interactions.

Avian Nutrition: Poultry, Ratite and Tamed Birds
by Nityanand PathakThe scope of book has relevant and important informations on some of the popular tamed birds reared as pet in cages. Among these Parrots and Mayana are companion species capable of learning and limited conversation with members of the house. Bulbul, partridges and pigeon are used for sports. Owners of these birds expect guidance for care and management from the experts of poultry science because so far there appears to be no school on the management of such avian species.Incorporation of these avian species in the book is expected to enrich the knowledge of students and teachers of the Avian and Poultry Science.Note: T& F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.
Avian Reproduction: From Behavior to Molecules (Advances in Experimental Medicine and Biology #1001)
by Tomohiro SasanamiThis book provides everything from basic knowledge to the recent understandings of avian reproductive physiology, covering many unique aspects. It will inspire avian biologists as well as researchers in varied fields and will offer important steps towards better fertilization success in birds. In spite of the recent remarkable developments in modern technology, a comprehensive understanding of the reproductive mechanisms is still far in the future due to the diverse reproductive tactics in vertebrates. Birds have highly refined reproductive strategies and some of those strategies are unique to birds. However, together with ongoing progress of the genome analysis of birds and the crying need for further increase in meat and egg production, research on avian reproduction is now accelerating and becoming more important. With contributions by leading scientists, the book explains avian primordial germ cells; the sex-determining mechanism; reproductive endocrinology and immunology; sperm, egg, and egg coat; sperm-egg interaction; polyspermic fertilization; seasonal reproduction; social triggers; hormonal and behavioral changes; broodiness; oviductal sperm storage; and biotechnology. This book is recommended for all researchers and students who are interested in birds or reproduction.
