Canada Geese flying over the house. This wouldn’t register as unusual except it was at night. When it gets dark we think of most birds tucking in a bushy spot or tree hollow to sleep. But during the spring and fall migration many birds take flight at night including geese.
Geese fly at both night and day but most usually begin at dusk. They move in a V formation, with experienced individuals taking turns leading the flock. Migrating flocks include loose groups of families generally.
Geese have excellent memories and vision especially with the full moon, allowing them to spot and remember landmarks on the ground and in the sky. Their ability to see in the dark is 12 times greater than ours.
Their autumn migration can be seen from September to the beginning of November. We usually see some Canada Geese year-round in mid-Michigan as long as there is unfrozen water. However some geese that breed in the High Arctic fly through Michigan to the southern United States for winter.
