Download or read book Snow and Blue Goose Distribution in the Mississippi and Central Flyways written by Alexander Dzubin and published by . This book was released on 1974 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The primary purpose of this compendium is to give detailed results of a Snow-Blue Goose (Chen caerulescens) band recovery analysis and provide supporting data to conclusions presented in a previous report, (Dzubin, Boyd and Stephen, 1973). Secondarily, it attempts to draw together population data which will aid managers, administrators and researchers to plan future programs or management strategies. The recovery data themselves are presented in a standardized format and are referenced in nine appendices, to aid resource managers in assessing the available distribution evidence"--Introduction, page 1.
Download or read book Wild Geese written by M. A. Ogilvie and published by A&C Black. This book was released on 2010-11-30 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: In range, Wild Geese covers the geese of North America, Europe and Asia, and thus the world species except for the Hawaiian Goose or Ne-Ne. The plan of the book is similar to the author's Ducks of Britain and Europe but distribution, status and migration rightly assume a more extensive role in Wild Geese and the detailed text on those subjects is fully complemented by migration and distribution maps. Comprehensive chapters are also devoted to classification, ecology, breeding, identification, and to exploitation and conservation. The identification chapter is especially helpful with sections on adult and first winter birds, downy young, plumage variants and voice, for each species and sub-species, as well as guidance on ageing and sexing geese in the field. The text is effectively supported by 16 identification plates in colour by Carol Ogilvie, showing details of heads and bills as well as all species in flight and on the ground, and downy young. The author is an established authority on ducks and geese and has been a research scientist at the Wildfowl Trust, Slimbridge, England, since 1960.

This book was released on 1999 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Razorbill Alca torda is one of the rarest breeding auks in North America. A number of surveys have been conducted at breeding colonies in recent years to estimate population size and trends. Summarizing the available data, we estimate that approximately 38 000 pairs of Razorbills currently breed in eastern North America. The largest concentrations of Razorbills breed on the Quebec North Shore and in coastal southern Labrador; smaller numbers breed in the Quebec portion of the gulf and estuary of the St. Lawrence River, Maine, New Brunswick, Nova Scotia, Newfoundland, and St. Pierre and Miquelon.

Download or read book Canadian Inland Seas written by I.P. Martini and published by Elsevier. This book was released on 2011-09-22 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: The various chapters of this book have been written by researchers who are still working in the Canadian Inland Seas region. The chapters synthesize what is known about these seas, yet much still is to be learnt. It is hoped that this collection of information will serve as a springboard for future, much needed, studies in this fascinating, diverse region, and will stimulate comparative analyses with other subarctic and arctic basins of the world. The Canadian Inland Seas are the only remnants, albeit cold, of the ancient cratonic marine basins which occupied central North America throughout the Paleozoic and part of the Mesozoic. Precambrian rocks and gently dipping Paleozoic sedimentary rocks underlie the seas. The area is also close to the centers of Pleistocene glaciations. The coastal areas represent an emerged landscape of the post-glacial Tyrrell sea, as the region has been isostatically uplifted to about 350 meters since glacial times. A total of 56 fish species inhabit Hudson Bay and James Bay. Seals, whales and one of the largest and southernmost populations of polar bears inhabit the seas as well. The coastal areas are important habitats for migratory bird populations, some of which migrate from as far away as Southern Argentina.The ostic environment has preserved these regions relatively unchanged by man, with only a major harbour at Churchill, Manitoba, which is active for part of the year, and a second large, rail-terminal settlement in the south at Moosonee, Ontario. A few, small, native Indian and Inuit villages dot the coasts. The seas are being affected indirectly by the damming of rivers for the generation of hydroelectric power, and by drainage diversions towards the man-made reservoirs. A major project is being completed in Quebec east of James Bay, but other rivers in Ontario and Manitoba have been dammed as well. Undoubtedly freshwater is one of the more important resources of the area, however its exploitation needs careful thought because of the possible long-range effects on the environment, particularly the coastal marshes, which sustain much of the eastern American intercontinental migratory avifauna. Other resources occur in the regions, primarily minerals and perhaps petroleum. For the most part however, such resources remain to be discovered.

Book excerpt: That is what this book is about. It is a framework for planning, in which habitat is the key to managing wildlife and making forest managers accountable for their actions. This book is based on the collective knowledge of one group of resource professionals and their understanding about how wildlife relate to forest habitats. And it provides a longoverdue system for considering the impacts of changes in forest structure on all resident wildlife.
