Mute Swan
Britain's classic white swan — curved neck, orange bill, and a presence on almost every royal park lake.
Least Concern
Cygnus olor
Overview
Mute swans are the familiar white swans of UK lakes, rivers, and park ponds: graceful on the water, powerfully territorial in the breeding season, and far less 'mute' than the name suggests when hissing at intruders.
For UK collectors, a swan gliding under willows is an everyday discovery that still feels premium on a Catch'Um card.
