Populations of resident Canada geese have dramatically increased over the past 25 years, particularly in urban areas where there are few predators, prohibitions on hunting, and a dependable year-round supply of food and water.anada geese hatched in urban environments may have very low first-year mortalities due to the abundance of food and relative scarcity of natural predators.
