Download or read book The Eastern Screech Owl written by Frederick R. Gehlbach and published by Texas A&M University Press. This book was released on 2008 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eastern screech owl, widespread over the eastern half of North America and noticeably tolerant of human activity, is one of America's most familiar birds. Residing naturally in wooded environs with tree cavities, this owl lives well in suburbia and can be found nesting in mailboxes, porch columns, and purple martin houses. Based on a twenty-five-year study, biologist Frederick R. Gehlbach tells the life story of the eastern screech owl, focusing on case studies of suburban and rural study plots in Central Texas. This is the first thorough study of major life-history, behavioral, and ecological features of the species. Indeed, it is the first concurrent, comparative study of an urban and a rural population of any New World animal. Told in a personal voice, the story of these birds will interest all who have not lost touch with their ancestral world. However, Gehlbach has also included quantitative data and analysis of interest to ecologists, wildlife biologists, and ornithologists. Photographs (including color shots of the gray and rufous phases), figures, and tables provide further detail. Gehlbach's investigations have been those of not only an academic ecologist, but a suburbanite curious about his natural surroundings. The result is a model of research on species population dynamics and adaptation, yielding an emerging picture of what the eastern screech owl needs for successful coexistence with human neighbors.
Download or read book Ecology and Conservation of Owls written by Ian Newton and published by CSIRO PUBLISHING. This book was released on 2002-08-12 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owls in Australia are difficult to find and study, so comparatively little is known about their biology. Even less is known about the status, taxonomy, and biology of those species and sub-species living in tropical and subtropical environments and on islands. Many island species and subspecies are at risk, some have already been lost. Ecology and Conservation of Owls includes sections on population ecology, distribution, habitat and diet, conservation and management, and voice structure and taxonomy. It contains a number of review chapters that bring together findings from a wide range of previous research, including recent developments in owl taxonomy and systematics, and studies of population limitation in northern hemisphere owls. The chapters in this book derive from papers presented at the Owls 2000 conference held in Canberra, Australia, which was third in a series of international meetings on owls.

Download or read book Urban Raptors written by Clint W. Boal and published by Island Press. This book was released on 2018-06-12 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Raptors are an unusual success story of wildness thriving in the heart of our cities—they have developed substantial populations around the world in recent decades. But there are deeper issues around how these birds make their urban homes. New research provides insight into the role of raptors as vital members of the urban ecosystem and future opportunities for protection, management, and environmental education. A cutting-edge synthesis of over two decades of scientific research, Urban Raptors is the first book to offer a complete overview of urban ecosystems in the context of bird-of-prey ecology and conservation. This comprehensive volume examines urban environments, explains why some species adapt to urban areas but others do not, and introduces modern research tools to help in the study of urban raptors. It also delves into climate change adaptation, human-wildlife conflict, and the unique risks birds of prey face in urban areas before concluding with real-world wildlife management case studies and suggestions for future research and conservation efforts. Boal and Dykstra have compiled the go-to single source of information on urban birds of prey. Among researchers, urban green space planners, wildlife management agencies, birders, and informed citizens alike, Urban Raptors will foster a greater understanding of birds of prey and an increased willingness to accommodate them as important members, not intruders, of our cities.

Download or read book Australian High Country Owls written by Jerry Olsen and published by CSIRO PUBLISHING. This book was released on 2011-11-15 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australian High Country Owls provides the latest scientific information on Australian owl species, especially Ninox owls. It details studies of Southern Boobooks and Powerful Owls, visits to North America and Europe to learn about owl research, and the resulting publications that overturned some existing beliefs about Australian owls. Ultimately, this led to the discovery of a new owl species in Indonesia, the Little Sumba Hawk-Owl. Appendices cover the biology, conservation and rehabilitation of Australian owls, including: field recognition, subspecies taxonomy, habitat, behaviour, food, range, migration, breeding, voice and calls, status and myths, questions about each species, and techniques for caring for injured and orphaned owls. The book includes numerous photographs of different owl species, and will be a handy reference for bird researchers and amateur bird watchers alike. 2012 Whitley Award Commendation for Vertebrate Natural History.

Download or read book Owls written by Marianne Taylor and published by HarperCollins. This book was released on 2016-11-22 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discover the fascinating and mysterious world of owls with this stunning full-color, encyclopedic visual guide that explores all 225 known species, packed with maps, photographs, illustrations, informative scientific details, and a bonus 35½" x 12" accordion poster illustrated with the true-to-size wing span of the largest owl, overlayed with the wing span of the smallest owl and several owls in-between. Humans have long been fascinated by owls. From prehistoric cave paintings to popular modern children’s stories, these magnificent predators have been seen as harbingers of good fortune and impending disaster, as icons of fear and wisdom, and as the powerful sidekicks of magic-makers, including the beloved Harry Potter. Scientists have faced tremendous challenges trying to document the lives of these solitary, nocturnal, and highly elusive creatures. New species are still being discovered, as are new insights into the habits of even the most familiar varieties. Visually spectacular and authoritative, Owls includes full descriptions and maps of key viewing locations for all 225 owl species in the world, and is illustrated with drawings and stunning full-color images from some of the leading wildlife photographers from around the world which capture these birds’ breathtaking beauty and power. The book also features a special section on the art of hiding—a highly honed skill set of the owl. Throughout, Marianne Taylor provides a wealth of detail on each type of bird’s hunting and breeding behavior, habitat, and conservation. Inside, are dozens of fun facts, such as: Only nineteen of the 225 known species of owls are found in North America; Owls can be found on all continents except Antarctica; Owls, like humans, have binocular vision; Owls cannot turn their eyes, but are able to rotate their heads up to 270 degrees; Owls are carnivorous and are known to eat rodents, small mammals, nocturnal insects, fish, and other birds. Lavishly illustrated and educational, this breathtaking volume is essential for readers interested in natural science, devout birders, professional ornithologists, and all owl lovers.

Available in PDF, EPUB and Kindle. Book excerpt: “You’ll come away from this riveting book blessed with owl wisdom that will enlarge your world forever.” —Sy Montgomery, author of Birdology and The Soul of an Octopus In this New York Times bestseller, Leigh Calvez explores the night forest to uncover the secret lives of owls in this illuminating book for birders, animal lovers, and readers of H is for Hawk. Join a naturalist on her adventures into the world of owls, owl-watching, avian science, and the deep forest—often in the dead of night. Whether you’re tracking snowy or great horned owls, these birds are a bit mysterious, and that’s part of what makes them so fascinating. In The Hidden Lives of Owls, Leigh Calvez pursues 11 different owl species—including the Barred, Flammulated, Northern Saw-Whet, Northern Pygmy, Northern Spotted, Burrowing, Snowy, and Great Gray. In an entertaining and accessible style, Calvez relays the details of her avian studies, from the thuggish behavior of barred owls—which puts the spotted owl at risk—to the highly unusual appearance of arctic snowy owls in the Lower 48, which directly reflects the state of the vole population in the Arctic. As Calvez takes readers into the lives of these strange and majestic creatures, she also explores questions about the human-animal connection, owl obsession, habitat, owl calls, social behavior, and mythology.

This book was released on 2009-02-27 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we document and evaluate the recovery of gray wolves (Canis lupus) in the Great Lakes region of the United States. The Great Lakes region is unique in that it was the only portion of the lower 48 states where wolves were never c- pletely extirpated. This region also contains the area where many of the first m- ern concepts of wolf conservation and research where developed. Early proponents of wolf conservation such as Aldo Leopold, Sigurd Olson, and Durward Allen lived and worked in the region. The longest ongoing research on wolf–prey relations (see Vucetich and Peterson, Chap. 3) and the first use of radio telemetry for studying wolves (see Mech, Chap. 2) occurred in the Great Lakes region. The Great Lakes region is the first place in the United States where “Endangered” wolf populations recovered. All three states (Minnesota, Wisconsin, and Michigan) developed ecologically and socially sound wolf conservation plans, and the federal government delisted the population of wolves in these states from the United States list of endangered and threatened species on March 12, 2007 (see Refsnider, Chap. 21). Wolf management reverted to the individual states at that time. Although this delisting has since been challenged, we believe that biological recovery of wolves has occurred and anticipate the delisting will be restored. This will be the first case of wolf conservation reverting from the federal government to the state conser- tion agencies in the United States.
