Download or read book The Great Blue Heron written by Robert William Butler and published by UBC Press. This book was released on 1997 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: With its striking plumage, the great blue heron is one of the most widely recognized wading birds in North America. Riding on kelp beds in the Queen Charlotte Islands, wading in coastal streams along the mainland, poised motionless at the water's edge on a misty morning, or nesting in the limbs of old-growth forests, this stately bird is a familiar sight on the coast of British Columbia. The largest colonies are on the Fraser River delta, an area of great ecological significance to the north Pacific. Despite a growing body of knowledge regarding many aspects of the species' breeding biology and courtship behaviour, the foraging and population ecology of this bird remains something of an enigma. In his beautifully illustrated book, Robert Butler follows the great blue heron through a year on the coast of British Columbia. He draws on more than a decade of work to throw light on the adaptability of this magnificent bird to a temperate climate, its diet and breeding habits, habitat use, and conservation. Although the great blue heron has become a symbol of wetland conservation, in recent years it has had to face new challenges as a consequence of rapid urbanization of its environment. In The Great Blue Heron the author also describes the B.C. coast and shares a vision for the conservation of the Strait of Georgia and the Fraser River delta.
Download or read book The North American Geese written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-08-23 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eight currently recognized species of North American geese are part of a familiar group of birds collectively called waterfowl, all of which are smaller than swans and generally larger than ducks. They include the most popular of our aquatic gamebirds, with several million shot each year by sport hunters. Our two most abundant waterfowl, the Canada goose and snow goose, have populations collectively totaling about 15 million individuals. Like swans, the lifelong pairbonding of geese, their familial care, and prolonged social attachment to their offspring are legendary. Their seasonal migratory flights sometimes span thousands of miles, and the sight of their long, wavering flight formations are as much the symbols of seasonal change as are the spring songs of cardinals or the appearance of autumnal leaf colors. This book describes each species' geographic range and subspecies, its identification traits, weights and measurements, and criteria for its age and sex determination. Ecological and behavioral information includes each species' breeding and wintering habitats, its foods and foraging behavior, its local and long distance movements, and its relationships with other species. Reproductive information includes each species' age of maturity, pair-bond pattern, pair-forming behaviors, usual clutch sizes and incubation periods, brooding behavior, and postbreeding behavior. Mortality sources and rates of egg, young, and adult losses are also summarized, and each species' past and current North American populations are estimated. In addition to a text of nearly 60,000 words, the book includes 8 maps, 21 line drawings, and 28 photographs by the author, as well as more than 700 literature citations.

Download or read book The North American Sea Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-11-09 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 21 species of sea ducks are one of the larger subgroups (Tribe Mergini) of the waterfowl family Anatidae, and the 16 species (one historically extinct) that are native to North America represent the largest number to be found on any continent, and also the largest number of endemic sea duck species native to any continent. Although generally not important as game birds, the sea ducks include some economically important birds such as the eiders, the basis for the Arctic eiderdown industry and a historically important food source for some Native American cultures. They also include what is probably the most northerly breeding species of all waterfowl and an icon of Arctic bird life, the long-tailed duck. The sea ducks also include species having some of the most complex and diverse pair-forming postural and acoustic displays of all waterfowl (goldeneyes and bufflehead), and some of the deepest diving species of all waterfowl (scoters and long-tailed duck). Sea ducks are highly prone to population disasters caused by oil spills and other water contaminants and, like other seabirds, are among the first bird groups that are being affected by current global warming trends in polar regions. This book is an effort to summarize succinctly our current knowledge of sea duck biology and to provide a convenient survey of the vast technical literature on the group, with over 900 literature references. It also includes 90,000 words of text (more than 40 percent of which is new), 15 updated range maps, 11 black & white and 20 color photographs, over 30 ink drawings, and nearly 150 sketches. Lastly, the North American sea ducks include the now extinct Labrador duck, the only northern hemisphere waterfowl species to have gone extinct in modern times. I have gratefully reprinted a Labrador duck watercolor by Sir Peter Scott. Considering recent population crashes in other sea ducks, such as the Steller’s eider and spectacled eider, it should also offer a sobering reminder of the fragility of our natural world and its inhabitants, including us.
Download or read book Wildlife Production Systems written by Robert J. Hudson and published by CUP Archive. This book was released on 1989-06 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, first published in 1989, examines the controversial position of commercial utilisation in relation to wildlife conservation. Production of large mammals has earned respectability as an agricultural strategy and its evaluation has been listed as a priority requirement in the World Conservation Strategy. However, many authorities question whether wildlife production is a viable economic and environmental strategy, and suggest that it runs counter to its claimed purpose. This book evaluates this controversy by chronicling the changing role of wildlife and by reflecting on the implications of these trends. The book should be of interest to people both applauding and deploring the use of wildlife in this economic role.

Download or read book Wildlife 2001 Populations written by D.R. McCullough and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1156 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1984, a conference called Wildlife 2000: Modeling habitat relationships of terrestrial vertebrates, was held at Stanford Sierra Camp at Fallen Leaf Lake in the Sierra Nevada Mountains of California. The conference was well-received, and the published volume (Verner, J. , M. L. Morrison, and C. J. Ralph, editors. 1986. Wildlife 2000: modeling habitat relationships of terrestrial vertebrates, University of Wisconsin Press, Madison, Wisconsin, USA) proved to be a landmark publication that received a book award by The Wildlife Society. Wildlife 2001: populations was a followup conference with emphasis on the other major biological field of wildlife conservation and management, populations. It was held on July 29-31, 1991, at the Oakland Airport Hilton Hotel in Oakland, California, in accordance with our intent that this conference have a much stronger international representation than did Wildlife 2000. The goal of the conference was to bring together an international group of specialists to address the state of the art in wildlife population dynamics, and set the agenda for future research and management on the threshold of the 21st century. The mix of specialists included workers in theoretical, as well as practical, aspects of wildlife conservation and management. Three general sessions covered methods, modelling, and conservation of threatened species.
