Mute Swan

The most commonly encountered swan globally and one of the largest flying birds, mute swans weigh up to 15 kg and inhabit lakes, rivers, and coastal bays across Europe and Asia, with widespread introduced populations in North America and Australia.

Males aggressively defend territories and are capable of injuring humans and drowning dogs with powerful wing strikes.
