This is a compilation of papers on the ecology of the Canada goose populations, beginning with a paper on the diversity of this species and the status of its different populations in North America. The remaining papers concern populations breeding in the Arctic, subarctic & boreal regions, and temperate regions. Topics covered include population status, distribution, survival, behaviour, surveys, breeding & nesting ecology, monitoring, and management.

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.

Migration timing is important to the reproductive success of birds, as mismatches with peak food abundance can lead to reduced fitness and population declines. Birds breeding at northern latitudes may be more susceptible to the effects of climate change, as narrower seasonality farther north can result in timing mismatches for birds that may rely more on endogenous cues to migrate. Few studies have used direct-tracking methods on waterfowl to compare differences in migration ecology across a latitudinal gradient. Spatiotemporal tracking data can also be useful for conservation and management of waterfowl. Giant Canada Geese (Branta canadensis maxima) are increasing in numbers, to the point where they are declared overabundant. Special hunting seasons may be opened to increase harvest of this subspecies, but care must be taken to avoid non-target goose populations. My first objective was to use direct-tracking data to examine differences in migration timing and rate between three goose populations: giant Canada Geese, Southern Hudson Bay Canada Geese (B. c. interior), and Cackling Geese breeding across a broad latitudinal range (49-65 degrees). My second objective was to apply my findings in relation to conserving and managing overabundant Canada Geese, and whether spring migration in overabundant Giant Canada Geese and less abundant Cackling Geese overlap with the proposed spring hunting season (March 1 to March 31). I found that southern-breeding geese migrated earlier and with more variation in spring compared to more northern-breeding geese, and in fall the northern-breeding geese migrated earlier compared to more southern-breeding geese. I also found that all three goose populations were in Manitoba during the fall hunting season, and about 9% of Giant Canada Geese were in Manitoba during the proposed spring hunting season. Increasing our knowledge of migration ecology in waterfowl can be useful in conservation of species that may be susceptible to the effects of climate change, or managing species that are increasing in numbers in which timing data can aid decisions to open special hunting seasons to increase harvest rates.

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.
