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.

Download or read book Managing Canada Geese in Urban Environments written by Arthur E. Smith and published by . This book was released on 1999 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you're a parks manager, waterfront property owner or golf-course superintendent, you may be dealing with one of the drawbacks of the Canada goose success story - resident, nonmigratory geese. As Canada goose numbers have soared in recent years, so have complaints about urban goose problems - primarily goose droppings, overgrazing and trampling of vegetation, and aggressive behavior toward humans. Managing Canada Geese in Urban Environments is a 42-page guide to legal, effective ways of persuading problem geese to go elsewhere. The guide includes an overview of goose biology and behavior, but most of the text is devoted to management and control techniques, arranged by their physical impact on the geese. The techniques range from basic (quit feeding the birds) to extensive - habitat modification, hazing and scaring techniques, chemical repellents, control of reproduction, and removal. For example, the habitat section reviews fences and overhead wires and grids, plant and rock barriers, and modification of vegetation, shorelines, islands and ponds. The hazing discussion covers noisemakers such as fireworks and propane cannons, goose scarecrows and other visual scare techniques, and dogs trained to patrol for geese. Tables provide a quick summary of timing, cost, necessary permits, strengths and weaknesses of each technique. The guide also discusses the human and political dimensions of urban goose management, and how to develop an integrated management strategy. It lists on-line information sources, as well as contact information for equipment suppliers and wildlife control agencies. "Urban Canada goose populations have increased dramatically in both numbers and distribution over the past 10 to 15 years. Almost any body of water, especially in southeast Wisconsin, can expect geese, if they aren't there already, " says co-author Scott Craven, extension wildlife ecologist at UW-Madison's College of Agricultural and Life Sciences. "Small numbers of geese are attractive and highly desirable, but it's very easy to quickly experience too much of a good thing. Information on living with geese has not been readily available, and some 'solutions' may have little chance of actual success. The guide provides would-be goose managers with the information they need to address a very complex urban wildlife problem." (http://www.cals.wisc.edu/media/news/02_99/goose_doo.html).

Download or read book The Implications of Agriculture in Interior Alaska for Population Dynamics of Canada Geese (branta Canadensis) written by Michael William Eichholz and published by . This book was released on 2001 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Understanding how environmental change affects demography is essential for understanding and managing populations. An anthropogenic change in the environment that has affected wildlife populations is widespread agricultural development. Agriculture has both negatively and positively impacted abundance of species by affecting a variety of vital rates that influence population abundance. In this study, I describe the migration ecology of Canada geese (Branta Canadensis) that nest and stage in Interior Alaska. I also describe how the introduction of agriculture has potentially positively impacted population dynamics of Canada geese by increasing nutrient acquisition, thereby improving their fecundity and survival. Two subspecies of Canada geese used Interior Alaska for staging and at least partially segregated themselves during spring and fall staging. I documented a difference in survival between two age classes of Canada geese, primarily lesser Canada geese (B. c. parvipes), and attributed it to the higher susceptibility to harvest of hatch-year (HY) geese. Estimates of annual survival of Canada geese in this study are among the lowest, and estimates of recovery rates are among the highest, for a migratory population of geese, likely due to behavioral traits and habitat selection that make lesser Canada geese more susceptible to harvest. Survival of after-hatch-year (AHY) female Canada geese was positively associated with the amount of endogenous nutrient reserves females had at the time of banding in fall. An experimental manipulation of nutrient reserves, however, suggested that the association between nutrient reserves and survival results from variation in individual quality (not measured), not a direct relationship between nutrient reserves and survival. Female geese in our study gained fat and minerals, but not protein, during spring staging. Fall staging geese had fat levels greater than or equal to spring staging geese, suggesting fat reserves are important during early fall staging in this population of geese. Although I concluded that the introduction of agriculture has likely increased fecundity and decreased natural mortality in Canada geese that stage and breed in Interior Alaska, I also concluded that mortality due to harvest is sufficient to offset those changes, preventing an increase in the population"--Leaves iii-iv

Available in PDF, EPUB and Kindle. Book excerpt: The Barnacle Goose, a distinctive, handsome black-and-white bird, gets its name from a mediaeval myth that the birds hatched from barnacles – how else to explain their sudden appearance each autumn in northern Britain? We now know, of course, that the birds migrate from Arctic Russia, Norway and Svalbard to winter throughout northern Europe. This book represents a culmination of more than 25 years of Barnacle Goose research. It represents the story of one of Europe's most celebrated long-term behavioral studies, detailing the lives of these social and sociable birds. Chapters include sections on pair formation and bonding, family and population dynamics, brood parasitism, food and feeding, size and shape in different populations, life cycle, survivorship, dispersal, migration, and conservation, with particular regard to climate change. It is a rigorous and thorough examination of the lives of these birds, in fine Poyser tradition.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The western Canada goose (Branta canadensis moffitti) was divided into a Rocky Mountain population (RMP) and a Pacific population (PP) on the basis of band recovery programs examined in this study and recovery data from other investigators. Habitat information provided a base line for evaluating future changes in nesting, molting, and wintering areas. Topics covered in the discussion of breeding biology are nesting chronology, spring population composition, breeding age, clutch size, nesting success, artificial nesting structures, and gosling survival. Some management recommendations include the refinement and standardization of spring and winter aerial surveys, and more accurate age and sex determinations when geese are banded and color-marked.

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.
