Use of Stockpods for Nesting by Giant Canada Geese
A study of giant Canada geese (Branta canadensis maxima) nesting on stockponds in western South Dakota was conducted during 1974 and 1975. Analysis of 10 selected variables at nests on natural sites indicated that distance of water below high water level and percent slope from wetland to horizon, …

The Impact of Nutrient Loading from Canada Geese (Branta canadensis) on Water Quality, a Mesocosm Approach
We conducted a mesocosm experiment to determine the impact of Canada Goose (Branta cana.densis) feces on water quality parameters. After 30 days of fecal additions (treatments of 2.419 g, 1.209 g and 12.090 g every 3 d) we found no significant impact on soluble reactive phosphorus, total …

Effects of body size on goose behavior: lesser snow goose and Ross's goose
Body size is highly variable among geese, both at intra- and interspecific levels. Interspecific variation in several behaviors has been attributed to differences in body size in geese: incubation constancy, tendency to maintain family units, and time spent foraging. Body size has important …
