The breeding season for Canada Geese starts in early March and will go until around May. The female chooses the spot for the nest which is a shallow bowl made up of sticks, grass, weeds, moss, and down feathers and slightly elevated off of the ground. She will lay up to eight eggs and be the only one who incubates it. The male stays nearby guarding the nest. After approximately 30 days the eggs will hatch and within twenty four hours the nestlings called goslings will be led to water. They already know how to walk, swim, dive, and feed. Both adults will raise them.
