CANADA GOOSE TERMS AND FACTS It is important to understand that all Canada geese migrate. Some simply migrate further than others. This has produced the following loose descriptive terms:
Migratory Canada geese: Flight range: 2,000-3,0000 miles
Move through our area in spring (going north), and fall (going south).
Resident Canada geese: Maintain a tighter flight range of up to 200 miles. These birds are capable of flying long distances, but have not learned to follow the migration pattern because they were not taught it by migrating parents.
Life Span: Up to 20 years (more typically 12-15 years). They mate for the life of their partner.
Weight: From 8-20 pounds (depending upon sub-species).
Natural Predators: In rural areas, predators may include fox, raccoon, owls, snapping turtles and coyote.
Nesting habits: Canada geese begin to nest at approximately 3 years of age, laying their nests in areas they feel they can defend. In the Rock River Valley this is often on ponds, lakes and on islands in rivers. The average number of eggs in a nest is 5. The nesting season runs from approximately March to May.
Molting: Fly feathers are lost during a "molting" period, typically in June. During this period, Canada geese are unable to fly.
The Canada Goose was thought to be nearly extinct in the 1950's. The population in the U.S. was probably around 50,000 birds. A very successful repopulation effort was launched at that time and now an estimated 1.5 million birds live on the Mississippi flyway alone.
