This book was released on 2001 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Populations of Giant Canada Geese (Branta canadensis maxima) have increased dramatically throughout most of the Mississippi Flyway. This population expansion has been accompanied by an increase in goose-related problems, including depredation of agricultural crops, airport hazards, fecal contamination of water used for drinking or swimming, and damage to lawns, parks, beaches, and golf courses, caused by overgrazing, trampling, feathers, and defecation. Failure to control giant Canada goose populations through traditional harvest methods such as hunting, has prompted interest in alternative harvest methods (nest manipulations, welfare harvest, and nesting female harvest) as a means of reducing goose numbers. The intent of this research was to generate long-term reproductive, survival and bioenergetics data and to utilize these data to develop a population model specific to Missouri Giant Canada Geese. The model was then used to identify population parameters that most influence population growth and to evaluate proposed management actions. Sensitivity analyses indicated that the effect of adult survival on population growth was much greater than any other population parameter. Alternative harvest simulations indicated that nesting female harvest was the most effective means of reducing populations to statewide management objectives. From a management perspective, our results indicate that efforts to control numbers of giant Canada geese should focus on reducing adult survival, in particular adult female survival. It is unlikely that the required reduction in adult survival necessary to reach management objectives will be achieved through traditional harvest methods. Therefore, a combination of non-hunting lethal alternatives will be required.

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.

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: During the past 15 years considerable attention has been focused on research and management problems associated with the Mississippi Valley population of Canada Geese. The general breeding, migration, and wintering ranges are well defined. Because this flock is closely associated with national wildlife refuges and State management areas in Wisconsin, Michigan, Ohio, Indiana, and Illinois, and the majority of this population winters in southern Illinois and vicinity, it has been possible to determine quite accurately annual total population trends, annual harvest rates, and the breeding potential of the population sent back to the breeding grounds each spring. Based on knowledge accumulated for this population, steps are being taken to compile similar information for other major continental Canada goose populations.

This book was released on 1976 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1960, the flock of giant Canada geese (Branta canadensis maxima)wintering at Rock Prairie, Wisconsin has declined from a mean of 3,000 in 1960-72 to 1,500-2,000 in 1973-74 and 1974-75. With the development of major concentrations of geese near the Horicon National Wildlife Refuge, 55 miles north, the use of Rock Prairie by migrating interior Canada geese (B.c. interior) in the fall has virtually ceased. Nesting habitat, mostly boreal forest on the Canadian shield in southeastern Manitoba, as a total environment, appears marginal. Breeding pair density observed on aerial surveys was 0.013 pairs per square mile. Leucocytozoon has been a major mortality factor of the goslings, claiming up to 50 percent of the annual production at the Alf Hole Provincial Sanctuary which supports the only known concentration of nesting geese associated with Rock Prairie. Hunting pressure has been intense in the Rock Prairie area and mortality at Rock Prairie has approached 10-15 percent of the ensui.
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).
