Average 45 inches in length; 68 inch wingspan
Found on shallow waters along the Chesapeake Bay and creeks, lakes, ponds, marshes and reservoirs. Frequents farm fields, parks and golf courses that are located near water. Always lives in flocks, except when nesting.
Abundant throughout the Chesapeake Bay watershed year-round. Most migrate to the Bay region in early autumn and remain through spring before returning to northern breeding grounds. Local resident populations stay in the region throughout the year.
Feeds primarily on corn and grains in farm fields; also eats bay grasses
20 to 25 years
The Canada goose has a brownish-gray back with tan or cream breast and underparts. It has a long, black neck and black head with a white “chinstrap” across the chin and cheeks. Its bill is black and rounded. It has a black tail with a white, U-shaped band on the rump. Canada geese grow to an average of 45 inches in length with a wingspan of about 68 inches, but can vary greatly in size.
The Canada goose feeds primarily on corn and grains in farm fields, but also eats bay grasses in the Bay’s shallows. In the water, it feeds by “tipping up” its tail to submerge its head underwater.
Humans hunt adult geese. Gulls, crows and other large birds may prey on eggs and young geese (called goslings). One or more mature geese usually stands guard against predators while other geese are feeding.
Flocks fly in wedge- or V-shaped formations, with older birds in front and younger birds in the back. The loud, honking flocks are often heard before they are seen. Geese usually take off from the water by running across the surface and flapping their wings. When they are startled, Canada geese can fly straight up from the water like dabbling ducks. To land, the goose holds its wings out straight and skids onto the land or water. It can be identified in flight by its long, straight neck and white, U-shaped band on its rump.
The goose has a deep, distinctive honk.
Reproduction and Life Cycle
Most Canada geese breed in the Arctic, though many now breed in the Bay region. Pairs often mate for life. The female build a nest of reeds, grass and down, usually on the ground near water. The male guards the nest against predators. The female lays 3 to 9 eggs that hatch in about one month. Goslings are fluffy and yellow. They begin to fly 40 to 70 days after birth. Canada geese can live as long as 20 to 25 years.
Did You Know?
- Canada geese are the most widespread goose in North America. Scientists believe there are 10 to 11 Canada goose subspecies. The smallest four are now considered a separate species: the cackling goose.
- Some consider resident Canada geese to be a nuisance because they can overgraze on lawns and crops. They also leave feces in parks, yards and other open areas, which is a significant source of pollution in many small, local waterways with large year-round goose populations.
