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 and 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.
