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 Please see the latest results for Bewick's Swan and Whooper Swan. Results of the 2005 census are available in Worden et al. (2006) (Bewick's Swan numbers and distribution) and will soon be available in Worden et al. (in prep) (Whooper Swan population size and breeding success). Getting involved The next census will take place in January 2010. More information on how to get involved will be available here in due course. For more information, please contact the Waterbird Monitoring Unit at WWT Slimbridge. Resources CUDI Data requests Field ageing guide Partner organisations Overall co-ordination by Wetlands International/ IUCN-SSC Swan Specialist Group. In the UK, the census is organised by WWT and the following partners: BirdWatch Ireland The Irish Whooper Swan Study Group Icelandic Institute of Natural History Icelandic Society for the Protection of Birds
