Mute swans and Canada geese in urban parks face welfare challenges from feeding human food, lead poisoning, fishing line entanglement, and harassment that require thoughtful public engagement.
Urban waterfowl face a paradox of human proximity: their habituation to humans makes them approachable and beloved but exposes them to welfare harms including inappropriate feeding, fishing line injury, and deliberate harassment. Bread feeding, though well-intentioned, provides empty calories that displace nutritious food in young birds and can cause permanent wing deformity. Entanglement in discarded monofilament fishing line causes progressive injury as the line tightens. A swan or goose found with line entanglement requires immediate professional help from wildlife rehabilitators.
