How Fast Is Mute Swan Flight?

Mute swans fly at 80 km/h. Among the heaviest flying birds at up to 14 kg, they are also famously aggressive when nesting — capable of breaking a man's arm with one strong beat of a wing.

Mute swans can break a man's arm with one beat of their wing — and routinely do attack people who get too close to nests.
