Canada Geese often build their nests on the ground near water leaving them open to predators. While they prefer a spots with an unobstructed view in multiple directions, it is the male's job to guard the female and the nest. Soon after they hatch, goslings spend most of their time sleeping and feeding and will remain with their parents constantly
