Scientific Name

A brown-backed, light-breasted goose with a black head and neck and white chinstrap and tail. They vary greatly in size from 4½ lbs. to 14½ lbs. Canada Geese breed across Canada and Alaska and winter mainly in the southern U.S. and Mexico, where they are firmly attached to certain breeding areas. Their V-shaped migrating flocks are a common sight in spring and fall.

Abundant

Activity Time

Diurnal

Diet

Herbivorous and consists mainly of leaves, grass, seeds, berries, algae, and roots

Behavior

The v-formation used by Canada geese in flight is very energy efficient, as is flying with the wind. This arrangement during flight is called a "wedge" or "skein." The lead position in the "wedge" is rotated because it is the most taxing flight position in terms of energy usage. This technique allows Canada geese to cover up to 2,400 km in a single day of flight. Flocks of geese are often vocal and communicate with each other during flight.

Ecological Role

Outside of North America Canada Geese are considered pests and even invasive. Ecologically, Canada geese have been observed to drive away native ducks and swans from nesting areas due to the press of their greater numbers, and to overgraze the shoots and rhizomes of aquatic plants. Their droppings also contribute to eutrophication in water. They are also considered to be a potential agricultural and park pest due to their heavy grazing of vegetation.
