Canada Goose
Aggressively territorial during nesting — but an animal that has essentially never seriously injured an adult human

Overview
Canada geese occupy a unique place in popular fear — a bird that people genuinely run from, despite being incapable of causing serious injury to an adult. The fear is real. The danger is not. They charge, hiss, and strike — but no adult has been hospitalized from a Canada goose attack on record.
Friendly fact
Canada goose families stay together through the goslings' first migration. Multiple families combine into creches with a few adults supervising many goslings while other parents feed — a community childcare arrangement.
Fascinating facts
- 1
Canada geese became dramatically more common after mid-20th century protection programs — from near-extinction to an estimated 5 million birds. Suburban fearlessness is partly a product of generations born near humans.
- 2
During nesting season, geese recognize individual humans and selectively harass people who have approached their nests before, while ignoring others.
- 3
Geese are monogamous for life — pairs stay together year-round, migrate together, and a widowed goose often remains alone for years before accepting a new mate.
- 4
Canada goose wing strikes cause bruising and shock but essentially never serious injury. Bites pinch. No adult hospitalization from a Canada goose attack is on record.
- 5
Their noise, droppings, and territorial aggression cause more problems for humans than any physical contact does.
Myth vs. Reality
Myth
Canada geese can break your arm.
Reality
Canada geese have hollow bones and weigh 3–9kg. Their wing strikes cause pain and bruising but cannot break human bones.
Myth
Canada geese are always aggressive.
Reality
Aggression is concentrated during the April–June nesting period. Outside nesting season, most Canada geese largely ignore humans.
