Saving wetlands for wildlife & people

International Swan Census

Species/Populations
Bewick’s Swan
Whooper Swan

History
First census carried out in 1986.

Aims
To estimate population size and identify important wintering sites.

Coverage
International (Eurasian flyways).

Frequency
Every five years.

Methods
One co-ordinated site-based survey timed to coincide with the International Waterbird Census. In the UK, also coincides with the Wetland Bird Survey Core Count, since this gives good general coverage. Counts at sites not covered through WeBS provide more complete survey. Counters also record the age structure of flocks, and the habitat being used.

Results
Results from the January 2010 census will be added to the web site when available.

Please see the latest results for Bewick's Swan and Whooper Swan.
