Book excerpt: Adult dusky Canada geese (Branta canadensis occidentalis Baird) were banded with plastic neck bands and observed on the winter range during 1985-92. Annual survival rates of adult geese estimated from observation data ranged from 76% to 85%. A model of Canada goose population dynamics was developed to illustrate relationships between survival rates, harvest regulations, and recruitment parameters and to predict trends in population size. Model simulations using recent estimates of survival and recruitment indicated that without significant increases in recruitment, survival rates must remain at or above present levels for the dusky Canada goose population to maintain itself. Observations of geese banded with tarsal and neck bands were used to estimate within-year survival rates and rates of neck band loss during 1990-92. Average monthly survival was 97% and was not significantly different among harvest and nonharvest periods (X2, P = 0.3882). Neck band retention rates were 100% and 98% the first and second year after banding, respectively, for male and female geese. Resighting probabilities for neck and tarsal bands were significantly lower for female than for male geese (X2, P

Download or read book Reproductive Ecology, Bioenergetics, and Experimental Removal of Local Giant Canada Geese (Branta Canadensis Maxima) in Central Missouri written by John Matthew Coluccy and published by . 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.

Book Synopsis The Rocky Mountain Population of the Western Canada Goose by : William B. Krohn
Download or read book The Rocky Mountain Population of the Western Canada Goose written by William B. Krohn and published by . This book was released on 1980 with total page 104 pages. 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 Synopsis The Implications of Agriculture in Interior Alaska for Population Dynamics of Canada Geese (branta Canadensis) by : Michael William Eichholz

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

Book Synopsis 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 by : Jeffrey Scott Gleason
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.
