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.

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 1999 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful management of Canada geese (Branta canadensis) requires an understanding of the factors which govern annual variation in reproductive success. We examined variation in nesting phenology, clutch size, nest survival, partial predation, egg size, and nest density for Eastern Prairie Population (EPP) Canada geese using data collected from 3 study areas in northern Manitoba from 1976-1996. The timing of nest initiation varied among years, and this variation was largely related to local weather conditions during the month of May. Mean clutch size declined with later annual nesting phenology, suggesting that delayed nesting results in higher energetic demands and reduced endogenous reserves for EPP geese. The relation between clutch size and relative nest initiation date within years was not linear, with the largest clutches being produced near the midpoint of initiation, and this relation was likely driven by a reduced allotment of nutrient reserves to egg production by early-nes.

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
