Long-term ringing surveys
There are currently two long-term ringing surveys that allow us to collect more detailed data on survival and productivity allowing us to understand population change - vital information for conservation.
- The Constant Effort Site (CES) Scheme monitors a range of passerines in the breeding season
- The Retrapping Adults for Survival (RAS) Scheme involves individual projects each collecting detailed information on one species.
- The Winter Ringing Project monitors a range of passerines during the winter months.
Other surveys
- The Swallow Roost Project, which took place between 2002 and 2006, was part of an international study of Swallows led by the European Union for Ringing (EURING).
