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.
Pairs disperse widely during the spring in search of nesting sites.
Islands, peninsulas and artificial nesting structures are preferred, but geese may also nest along shorelines,in abandoned raptor nests or on the tops of tree stumps. Nests are almost always near water. Nesting begins during late March or early April but the date may vary a week or two depending on spring temperatures. Goslings leave the nest within a day or two but remain flightless for ten weeks. Adult geese molt their primary flight feathers and become grounded during the latter portion of the brood-rearing period.
