Book Description
This research project has presented research and a proposed methodology aimed at studying the survival and harvest rates of Canada goose (Branta canadensis) populations. Additionally, this study proposes methods for comparing these rates between urban and rural populations of Canada geese. This is accomplished by pooling data from both populations relating to banding and direct recovery rates whereby annual survival estimates can be made via the program MARK available in the RMark package with a joint live-dead recovery model. Models were then designed to incorporate predetermined covariates and then fitted to assess for differences in survival between urban and rurally banded individuals. Model estimated rates for annual survival and direct recovery were then used to calculate annual harvest rates for the populations. Models are then able to be evaluated by performing a likelihood ratio test, to determine if two models differ based on the impact of time-varying covariates upon the overall variance within the models. These simulations will then be repeated 1,000 times for each model comparison. Comparisons of rural and urban goose survival and harvest rates may allow for a more informed management approach for the species, especially in urban environments where hunting is often not a feasible management option.

Book Description
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.

Book Description
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 Description
Temperate-nesting Canada geese in Arkansas have grown in abundance and range since reintroduction in the 1980s. The Arkansas Game and Fish Commission uses harvest and other methods to maintain the population at desired levels. However, continued management of temperate-nesting geese requires knowledge of the population's demographics and current range to help establish quantifiable management goals. To assess the need and effect of changing hunting regulations, survival and recovery rates and abundance were estimated for this population. Annual survival rates of temperate-nesting Canada geese banded and recovered in Arkansas from 2005 to 2011 were estimated using the Burnham joint live-dead recovery model in program MARK. Candidate models were created to allow survival to vary by age (adult, young), time (year), and potential hunting pressure (pre- vs. post-liberalization). The abundance of temperate-nesting Canada geese in Arkansas from 2002-2011 was estimated using the Lincoln Index and either an unadjusted Lincoln Index, using a Mississippi Flyway Canada goose harvest rate, or an adjusted Lincoln Index, using a regional harvest rate estimate. Target harvest rates based on the Potential Biological Removal framework were estimated for a range of recovery factors associated with different potential management strategies using model-averaged survival rates and unadjusted Lincoln Index estimates. Despite recent relaxed hunting regulations, neither annual survival rates nor abundance of temperate-nesting Canada geese in Arkansas have declined. Range from 2004-2012 was estimated using volume contour maps from citizen science observations using eBird and hunter recovery locations from the U.S. Geological Survey Bird Banding Laboratory. Dispersal of temperate-nesting Canada geese banded and recovered in Arkansas was examined. Emigration, molt migration, and immigration between Arkansas and other states and provinces was examined using geese banded in Arkansas and recovered elsewhere and geese banded elsewhere and recovered in Arkansas. Emigration and immigration interactions were greatest between Arkansas and Missouri. Molt migrant interactions were greatest between Arkansas and Manitoba and Minnesota. Factors explaining molt migration/emigration were examined, and both age and sex were the best predictors. Overall, geographic analysis indicated the range of temperate-nesting Canada geese in Arkansas is expanding, but individual geese do not frequently move long distances from banding sites.
