They nest in over one-half of Missouri's counties, most commonly in northern and western regions and along the Missouri River. Canada geese have adapted to civilization and are firmly established in cities such as St. Louis, Kansas City, Columbia, Springfield and Jefferson City. Canada geese are highly prized game birds and are enjoyed by birders, photographers and casual observers. Their presence in some locations, however, may result in problems. Goose flocks near airports are an aviation hazard, and in rural areas geese can damage crops.
Most problems result from goose droppings in urban or semi-residential locations.
Lawns, golf courses and community or subdivision lakes provide ideal loafing, roosting and grazing areas for geese. Droppings on shorelines, swimming beaches and docks are a nuisance and vegetation can be damaged by too much grazing or trampling. Identification Canada geese can be distinguished from other geese by their black bill, legs and feet and by the distinctive black head and neck with a white cheek patch. Giant Canadas are the only wild goose to commonly nest in Missouri. General Biology Pairing may occur at one or two years of age, but few individuals will nest prior to three years of age.
