Birds have been ringed in
Britain and Ireland for nearly a hundred years and it still reveals new facts about migration routes and wintering areas. The primary focus of the BTO's ringing schemes is now the monitoring of bird populations, to provide information on how many young birds leave the nest

The BTO runs two specialized projects to collect this information. The
Constant Effort Sites (CES) scheme provides information on population size, breeding success and survival of bird species living in scrub and wetland habitats. Ringers work at over 130 CES scheme sites each year. The Retrapping

Warblers breeding in Britain and Ireland was linked to lower levels of rainfall in their African wintering quarters; whilst the recent dramatic decline in the numbers of Song Thrushes was found to relate to a reduction in the survival rate of

Much has been discovered about birds by watching and counting them, but such methods rarely allow birds to be identified as individuals. This is essential if we are to learn about how long they live and when and where they move, questions that are vital for bird conservation.

Each ring also has an address so that anyone finding a ringed bird can help by reporting where and when it was found and what happened to it. Some ringing projects also use colour rings to allow individual birds to be identified without being caught.
