Download or read book Influence of Sympatric Lesser Snow Geese Chen Caerulescens Caerulescens on Reproductive Performance Behavior and Food Habits of Canada Geese Branta Canadensis Interior on Akimiski Island Nunavut written by Jeffrey Scott Gleason and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2003 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on Akimiski Island, Nunavut, indicates declining numbers of nesting Southern James Bay Population (SJBP) Canada Geese (Branta canadensis interior) while increases have been documented for number of breeding Lesser Snow Geese (Chen caerulescens caerulescens). Low direct recovery rates of goslings is suggestive of late-summer mortality which may be limiting recruitment for Canada geese on Akimiski Island. This study was designed specifically to (1) compare Canada Goose reproductive performance, incubation and brood-rearing behavior in areas of allopatry and sympatry and with Lesser Snow Geese, (2) determine if there are differences in diets of Canada Geese in areas of allopatry and sympatry, and (3) determine if there are differences in diets of Canada and Lesser Snow Geese in the area of sympatry. I documented annual variation for all and spatial variation for some reproductive parameters measured. Results of between-area comparisons of reproductive performance tended to suggest that in some years, Canada Geese nesting in the area of sympatry contribute little towards the maintenance of the island segment of this population. During incubation when females were on nests, male behavior varied as a function of year, area, time-of-day, and incubation stage. Overall, male Canada Geese allocated their time primarily to vigilance, feeding, and resting when females were on the nest. Males in the area of allopatry were more vigilant and fed less compared to males in the area of sympatry. When females were on the nest, their behavior varied relative to time-of-day, incubation stage, and temperature. Females in the area of allopatry were more vigilant than females in the area of sympatry, but overall, females on the nest allocated their time primarily to resting and maintenance. Recess behavior of Canada Geese varied relative to sex, incubation stage, and temperature, but not area, though pairs in the area of allopatry tended to spend more time alert and less time feeding compared to pairs in the area of sympatry. During recesses, males allocated their time primarily to vigilance, whereas females allocated nearly equal proportions of time to feeding and maintenance. Overall, brood-rearing behavior varied relative to year, area, time-of-day, sex/age class, days since peak hatch, brood size, brood density, and temperature. Overall, results are indicative of exploitation competition and I suggest that present foraging conditions are insufficient to meet the energetic demands of breeding Canada Geese, as well as breeding and staging Lesser Snow Geese, molt-migrant Giant Canada Geese, and staging Atlantic Brant. Such an energy deficit is particularly detrimental to the growth and development of Canada Goose goslings resulting in locally poor recruitment which presumably will lead to a much depressed breeding population of Canada Geese on Akimiski Island.

Available in PDF, EPUB and Kindle. Book excerpt: "This revised edition is not an expanded version of the original, summarizing, for example, the dozens of studies that hve been made of the productivity of various subpopulations of the "Giant Canada Goose" since its rediscovery. Rather, the main objectives of this revised, slightly enlarged edition are to redefine the range of this race as it was originally understood and to correct earlier assumptions based on the literature as to racial identity of peripheral populations."--Page xvii.

This book was released on 2014-10-17 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years in the making, The Kentucky Breeding Bird Atlas presents the results of a seven-year survey of all birds that nest in the Bluegrass State, providing photographs of each species. This work summarizes the distribution and abundance of these bird species, and describes such recent phenomena as the invasions of the Blue Grosbeak and House Finch and the notable decline of other familiar species. Introductory material outlines the methodology used to complete the survey and summarizes its results. Of particular interest, this work helps to document the effect human alteration of the landscape has had on our bird populations. Some of the most common and widespread species in Kentucky today, for example, may have been among the most rare only two hundred years ago. Information for each species includes its current and historical status in the state, habitat preferences, specific details of the construction and placement of nests, and other pertinent aspects of nesting biology. Results of the survey are organized by physiographic region and degree of forestation. For rare or locally distributed species, more specific details concerning individual breeding records are given. Accompanying maps plot each species' distribution and abundance within the state. An additional section briefly summarizes the former status of twelve extinct or extirpated species. The Kentucky Breeding Bird Atlas is sponsored by the Kentucky State Nature Preserves Commission and the Nongame Wildlife Program of the Kentucky Department of Fish and Wildlife Resources in cooperation with the Kentucky Ornithological Society.

Download or read book Field Guide to the Birds of East Asia written by Mark Brazil and published by Bloomsbury Publishing. This book was released on 2019-08-22 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first single volume guide ever devoted to the eastern Asian avifauna. The eastern Asian region, centring especially on the major islands off the continental coast (including Japan and Taiwan) and the immediately adjacent areas of the Asian continent from Kamchatka in the north and including the Korean Peninsula are an important centre of endemism. Birds endemic to this region include representatives of many of the major families, from the world's largest eagle - Steller's Sea Eagle - to the tiny Formosan Firecrest. The east Asian continental coast and the offshore islands also form one of the world's major international bird migration routes, especially for waterfowl, shorebirds and raptors, while the east Asian continental mainland itself is home to a wide range of species little known to western ornithologists such as Scaly-sided Merganser, Oriental Stork and Mugimaki Flycatcher. The guide features the most up-to-date text available, which, in conjunction with extensive colour plates throughout, facilitates the field identification of all of the species known from the region. Colour distribution maps enhance the text by providing a visual analysis of the summer, winter and migratory ranges of all species.

Download or read book Turmoil and Triumph written by Ian Bickle and published by Calgary : Detselig Enterprises Limited. This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a story of courage and adventure. It reveals how workers struggled through long days, enduring extreme weather, pests, and the often poor food and housing, as they built a railway through the difficult terrain of Canada's northern wilderness to Churchill, Manitoba. Author Ian Bickle provides rare insight into the survey parties who explored this region of ice, snow, swamp and muskeg. He gives a historical account of the organizations, such as the RNWMP (later RCMP), that helped bring order and discipline to the rugged life on the line, and Frontier College teachers, who assisted the workers in their labors and their education. The men who surveyed the Bay route, the workers who built it and the people who keep it alive have raised the level of human achievement in Canada. Their story is an important and colorful part of Canadian history.
