This book was released on 2020-03-31 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professor Cody's monograph emphasizes the role of competition at levels above single species populations, and describes how competition, by way of the niche concept, determines the structure of communities. Communities may be understood in terms of resource gradients, or niche dimensions, along which species become segregated through competitive interactions. Most communities appear to exist in three or four such dimensions. The first three chapters describe the resource gradients (habitat types, foraging sites, food types), show what factors restrict species to certain parts of the resource gradients and so determine niche breadths, and illustrate the important role of resource predictability in niche overlap between species for resources they share. Most examples are drawn from eleven North and South American bird communities, although the concepts and methodology are far more general. Next, the optimality of community structure is tested through parallel and convergent evolution on different continents with similar climates and habitats, and the direct influence of competitors on resource use is investigated by comparisons of species--poor island communities to species-rich mainland ones. Finally, the author discusses those sorts of environments in which the evolution of one species--one resource set is not achieved, and where alternative schemes of resource allocation, often involving several species that act ecologically as one, must be followed.

Available in PDF, EPUB and Kindle. Book excerpt: How does a bird experience a city? A backyard? A park? As the world has become more urban, noisier from increased traffic, and brighter from streetlights and office buildings, it has also become more dangerous for countless species of birds. Warblers become disoriented by nighttime lights and collide with buildings. Ground-feeding sparrows fall prey to feral cats. Hawks and other birds-of-prey are sickened by rat poison. These name just a few of the myriad hazards. How do our cities need to change in order to reduce the threats, often created unintentionally, that have resulted in nearly three billion birds lost in North America alone since the 1970s? In The Bird-Friendly City, Timothy Beatley, a longtime advocate for intertwining the built and natural environments, takes readers on a global tour of cities that are reinventing the status quo with birds in mind. Efforts span a fascinating breadth of approaches: public education, urban planning and design, habitat restoration, architecture, art, civil disobedience, and more. Beatley shares empowering examples, including: advocates for “catios,” enclosed outdoor spaces that allow cats to enjoy backyards without being able to catch birds; a public relations campaign for vultures; and innovations in building design that balance aesthetics with preventing bird strikes. Through these changes and the others Beatley describes, it is possible to make our urban environments more welcoming to many bird species. Readers will come away motivated to implement and advocate for bird-friendly changes, with inspiring examples to draw from. Whether birds are migrating and need a temporary shelter or are taking up permanent residence in a backyard, when the environment is safer for birds, humans are happier as well.

Download or read book The Ecology of Bird Communities written by John A. Wiens and published by Cambridge University Press. This book was released on 1989 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two volumes of John Wiens' Ecology of Bird Communities, first published in 1992, are recognised as having applications and importance beyond the study of birds to the wider study of ecology in general. The books contain a detailed synthesis of our understanding of the patterns of organisation of bird communities and of the factors that may determine them, drawing from studies from all over the world. The author, however, does more than simply review findings in bird community ecology. By emphasizing how proper logic and methods have or have not been followed and how different viewpoints have developed historically and have led to controversy, he extends the scope of these books far beyond the study of birds. Volume 1 Foundations and Patterns explores why avian community ecologists ask the questions they do and what philosophical and methodological approaches they have used to answer such questions. Most of the book is devoted to a critical evaluation of what is known about the nature and organisation of bird communities.

Download or read book Bird Brother written by Rodney Stotts and published by Island Press. This book was released on 2022-02-03 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Bird Brother, Rodney Stotts shares his unlikely journey to becoming a conservationist and one of America's few Black master falconers. Rodney grew up in Washington, D.C. during the crack epidemic, with guns, drugs, and the threat of incarceration affecting the lives of everyone he knew. He was no exception, but he was also employed by the newly founded Earth Conservation Corps, helping to restore and conserve the polluted Anacostia River. This work eventually sent his life in a different direction, as he began to train to become a master falconer and to develop his own raptor education program and sanctuary. Eye-opening, witty, and moving, Bird Brother is a testament to the healing power of nature, and a reminder that no matter how much heartbreak we've endured, we still have the capacity to give back to our communities and follow our dreams.

Download or read book Ecology and Conservation of Birds in Urban Environments written by Enrique Murgui and published by Springer. This book was released on 2017-02-10 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides syntheses of ecological theories and overarching patterns of urban bird ecology that have only recently become available. The numerous habitats represented in this book ranges from rows of trees in wooded alleys, to wastelands and remnants of natural habitats encapsulated in the urban matrix. Authored by leading scientists in this emergent field, the chapters explore how the characteristics of the habitat in urban environments influence bird communities and populations at multiple levels of ecological organization and at different spatial and temporal scales, and how this information should be incorporated in urban planning to achieve an effective conservation of bird fauna in urban environments. Birds are among the most conspicuous and fascinating residents of urban neighborhoods and provide urban citizens with everyday wildlife contact all over the world. However, present urbanization trends are rapidly depleting their habitats, and thus knowledge of urban bird ecology is urgently needed if birds are to thrive in cities. The book is unique in its inclusion of examples from all continents (except Antarctica) in an effort to arrive at a more holistic perspective. Among other issues, the individual chapters address the censusing of birds in urban green spaces; the relationship between bird communities and the structure of urban green spaces; the role of exotic plant species as food sources for urban bird fauna; the influence of artificial light and pollutants on bird fauna; trends in long-term urban bird research, and transdisciplinary studies on bird sounds and their effects on humans. Several chapters investigate how our current knowledge of the ecology of urban bird fauna should be applied in order to achieve better management of urban habitats so as to achieve conservation of species or even increase species diversity. The book also provides a forward-looking summary on potential research directions. As such, it provides a valuable resource for urban ecologists, urban ecology students, landscape architects, city planners, decision makers and anyone with an interest in urban ornithology and bird conservation. Moreover, it provides a comprehensive overview for researchers in the fields of ecology and conservation of urban bird fauna.

Download or read book Beaks Bones and Bird Songs written by Roger Lederer and published by Timber Press. This book was released on 2016-06-22 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Reveals the strange and wondrous adaptations birds rely on to get by.” —National Audubon Society When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don’t see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones, and Bird Songs guides the reader through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter. Or urban birds, which navigate traffic through a keen understanding of posted speed limits. In engaging and accessible prose, Roger Lederer shares how and why birds use their sensory abilities to see ultraviolet, find food without seeing it, fly thousands of miles without stopping, change their songs in noisy cities, navigate by smell, and much more.

Available in PDF, EPUB and Kindle. Book excerpt: “A wonderful book that highlights the globally unique and important boreal forest ecoregion from an avian perspective, with fresh twists. Your ideas about where those migrant and wintering birds in your backyards have come from will be forever changed after you read this.”--Gordon Orians, Professor Emeritus of Biology, University of Washington “One of the planet's most amazing spectacles is the seasonal ebb and flow of migrants from the boreal forests to warmer winter quarters, with stopovers in our neighborhoods in between. This book tells you how connected the world is and what's at risk if we damage any part of it.”--Stuart Pimm, Doris Duke Professor of Conservation Ecology, Duke University, winner of the 2006 Dr. A. H. Heineken Prize “This diverse set of contributions about birds that nest in and migrate to and from North America's boreal forest demonstrates the remarkable interconnectedness of ecosystems across the hemispheres and the incredible responsibility we face to protect them.”--Bridget Stutchbury, York University, author of Silence of the Songbirds and The Private Lives of Birds “The fact that billions of birds breed in North America’s boreal forest is amazing enough, but this assemblage is even more remarkable when understood as playing completely different, major ecological roles across the temperate and tropical Americas during the northern winter. This book definitely will broaden your thinking about ecological connections across the hemisphere and the global-scale phenomenon that crosses our skies twice each year.”--John W. Fitzpatrick, Louis Agassiz Fuertes Director, Cornell Lab of Ornithology

Download or read book Bird Habitats in Britain written by R. J. Fuller and published by A&C Black. This book was released on 2010-09-30 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes all the main habitat types, the structure and composition of bird communities, and reviews bird sites and their distribution throughout Britain. Rob Fuller's book would not have been possible but for the nationwide cooperative endeavour by amateur and professional ornithologists, naturalists and conservationists which led to the British Trust for Ornithology's Register of Ornithological Sites, sponsored by the Nature Conservancy Council. Hitherto, few books have dealt primarily with bird habitats but the subject is of urgent importance now that exploitation of the environment has left few corners of Britain untouched or unthreatened. Even so, the book is much more than timely, it also extends the reader's interest to an area of bird study that has, perhaps, been too little considered. The text is supported by more than 100 diagrams and maps, and over 50 photographs; in addition there are 53 superbly evocative drawings by Donald Watson. For the birdwatcher and all involved with conservation, this is stimulating reading and an essential reference.

Download or read book Breeding Bird Communities in Aspen Forests of the Sub boreal Spruce dk Subzone in the Prince Rupert Forest Region written by Rosamund A. Pojar and published by Research Branch, Ministry of Forests. This book was released on 1995 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reports a two-year study initiated to examine the diversity of bird communities in different seral stages of the aspen ecosystem at the western end of the dry cool subzone of the sub-boreal spruce zone of the Prince Rupert Forest Region, British Columbia. Breeding birds were chosen for the study since they tend to stay within a relatively confined area once in their territories and are hence easier to count. The study also had the objective of identifying management indicator species that could represent the diversity of most birds likely to be affected by aspen management. Birds were counted by a modified point count method for clearcuts, sapling aspen stands, mature aspen stands, old aspen stands with century-old trees, and mixed aspen-conifer stands. Data were analyzed using a detrended correspondence analysis ordination procedure, and habitat relationships of the 16 most abundant species were analyzed by multiple regression.
