Book Synopsis The Great Blue Heron by : Robert William Butler
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.

Book Synopsis The Patient Predator by : Robert William Butler
Download or read book The Patient Predator written by Robert William Butler and published by Canadian Museum of Civilization/Musee Canadien Des Civilisations. This book was released on 1995 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a six-year study of the great blue heron (Ardea herodias) on British Columbia's Pacific coast. The study period included five breeding seasons and four winters. The researchers studied a colony of 85-100 pairs on Sidney Island and visited about 40 other colonies around the Strait of Georgia over 1986-91. This report presents the results of the study, with information on the heron's diet, food availability, foraging behavior, use of habitats by age-classes and sex-classes, seasonal shifts in habitat use, spacing of breeding colonies in relation to predators and foraging habitats, effects of nest site selection and time of breeding on breeding success, and local survival of age-classes.
Book Synopsis Behaviours Influencing the Distribution of Great Blue Herons (Ardea Herodias Fannini) in the Strait of Georgia, British Columbia [microform] by : James Kenneth Kenyon
Download or read book Behaviours Influencing the Distribution of Great Blue Herons (Ardea Herodias Fannini) in the Strait of Georgia, British Columbia [microform] written by James Kenneth Kenyon and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2005 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Blue Heron (Ardea herodias fannini), a nonmigratory subspecies endemic to the Pacific Northwest of North America, is COSEWIC-listed in Canada as a species of 'special concern'. The Breeding Bird Survey (BBS), conducted since 1969, indicate an ongoing decline in numbers. Recent findings show that nest and colony abandonments are common, and are strongly associated with disturbance by bald eagles (Haliaeetus leucocephalus). Vanishing bearings of herons departing foraging sites were strongly associated with colony locations, and led to the discovery of small, previously unknown colonies. A probabilistic model predicted that dispersed nesting offers increased nestling safety under high eagle depredation. Ideal free distributions accounting for colony locations as well as foraging-site size and quality best matched the observed distribution of foraging herons. These findings support the hypothesis that great blue herons have redistributed into smaller, more widely-scattered colonies as eagle numbers have recovered over recent decades.

Download or read book Birds of British Columbia, Volume 4 written by Wayne Campbell and published by UBC Press. This book was released on 2001-02-23 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: This much-awaited final volume of The Birds of British Columbia completes what some have called one of the most important regional ornithological works in North America. It is the culmination of more than 25 years of effort by the authors who, with the assistance of thousands of dedicated volunteers throughout the province, have created the basic reference work on the avifauna of British Columbia. Volume 4 covers the last half of the passerines and describes 102 species, including the warblers, sparrows, grosbeaks, blackbirds, and finches. The text builds upon the authoritative format of the previous volumes and is supported by hundreds of full-colour illustrations, including detailed distribution maps, unique habitat shots, and beautiful photographs of the birds, their nests, eggs, and young. In addition, a species update lists and describes 27 species of birds new to the province since the first three volumes were published. The book concludes with Synopsis: The Birds of British Columbia into the 21st Century, which synthesizes data and information from all four volumes and looks at the conservation challenges facing birds in the new millennium. The four volumes in The Birds of British Columbia provide unprecedented coverage of the region's birds, presenting a wealth of information on the ornithological history, regional environment, habitat, breeding habits, migratory movements, seasonality and distribution patterns of 472 species of birds. It is the complete reference work for birdwatchers, ornithologists and naturalists.
