Whooper Swan

Cygnus cygnus

Whooper swan, Cygnus cygnus, is the large yellow-billed swan of northern Eurasia and Iceland. It breeds on remote lakes, bog pools, and slow rivers across boreal and subarctic regions, then winters on wetlands, estuaries, flooded fields, and managed reserves farther south. The bill has a broad yellow wedge reaching toward the nostrils, which helps separate it from Bewick's or tundra swans. Long white necks, strong flight, and loud whooping calls make migrating family groups easy to notice.

For people, whooper swans are most often protected wild birds seen at reserves, winter feeding stations, and migration watch sites. Conservation work may include wetland protection, ringing or satellite tracking, reducing lead exposure, and managing disturbance during harsh weather. In waterfowl collections, they need far more than a decorative pond: broad water, grazing space, secure fencing, and protection from predators are basic expectations. Pairs can be territorial during nesting, so placement with other waterfowl has to be planned carefully, and permits or reporting rules may apply depending on the region.
