The breeding biology and population dynamics of Canada geese nesting at Dowling Lake, Alberta were studied during 1971-1975. The purpose of the research was to examine the factors affecting survival in this population, especially during the brood rearing period. Breeding pairs did not appear to compete for snow-free locations on the breeding islands in early spring. Territories established during this period decreased in size with the encroachment of later nesting pairs. Nest and territory spacing approached uniformity, but behavioral differences and heterogeneity of the vegetation prevented realization of a statistically significant uniform pattern. Artificial nesting platforms were constructed to increase the nesting density of Canada geese on the large breeding island. Thirty-five, 39, 20, and 39 percent of the available platforms were used as nest sites in 1971-1974, respectively. Platform nesting success was no different than that of ground nesting geese and there was no signific.

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.

A study of the relationship between density and territorial behavior during the period of incubation of nesting Canada geese (Branta canadensis ssp.) was conducted on a 16-acre island in Dowling Lake, Alberta. Densities of nesting geese were recorded as 8.0, 10.7, and 9.2 nests per acre for 1967 through 1969 respectively. Nesting success (hatching at least one egg varied from 60 to 27 to 69 percent for the three respective years. Coyote predation, responsible for 50 percent of nest loss in 1968, was related to low water levels. Rates of desertion remained constant over the three years at 18, 21, and 22 percent respectively. Small sizes of territories, high densities of nesting pairs, large numbers of nesting pairs, and the presence of non-territorial geese resulted in a relatively constant level of antogonism throughout incubation. Pairs that were successful in hatching all or part of their clutches always won more interactions with neighboring pairs and with non-territorial geese. Mo.
