Canada geese (Branta canadensis) and greylag geese (Anser anser) have become abundant in urban parks, golf courses, and suburban areas across North America and Europe, creating significant human-wildlife conflict and management challenges. Navigating this conflict with welfare-positive approaches requires understanding goose ecology and the full range of management options.
Canada geese were reintroduced to many areas in the 20th century as hunting birds and have adapted spectacularly to urban environments. Manicured grass lawns provide ideal foraging habitat; lack of predators and prohibition on hunting in urban areas allow populations to grow unchecked. Urban flocks grow year-round as migratory birds abandon migration in favor of year-round urban food resources.
Human-wildlife conflicts involving geese create welfare concerns on multiple sides. Geese defending nests and young are aggressive toward people, causing physical injuries — particularly to children and elderly individuals. This aggression can result in public pressure for culling that removes the welfare of individual geese from consideration entirely.
Conversely, geese targeted for culling by lethal population management experience fear, capture stress, and death — welfare costs that are often unacknowledged in management discussions framed purely as pest control.
Welfare-positive management prioritizes non-lethal approaches:
Where lethal control is deemed necessary, welfare considerations require: use of methods minimizing suffering, avoiding breeding season where possible (orphaned goslings face welfare harm), complete retrieval of killed birds, and humane killing methods. "Roundup and euthanize" operations during molt — when geese cannot fly — are sometimes conducted; welfare during these operations requires appropriate stunning before killing.
Feeding geese in parks dramatically increases local population density and human habituation, increasing conflict. Public education campaigns discouraging goose feeding reduce population pressure while improving goose welfare — bread and junk food fed by well-meaning members of the public causes nutritional deficiencies and "angel wing" deformity in goslings.
