Bat ringing refers to the technique of applying a small ring to the forearm of a bat to allow for individual identification. It cannot be done without a licence from the Statutory Nature Conservation Body (SNCB also known as SNCO). Only experienced proven individuals are able to obtain such licences.
The ability to recognise individual bats enables researchers to estimate population size and survivorship, study roost fidelity and social relationships, and investigate migratory movements, to name a few.
Ringing and the associated capture of bats are amongst the most invasive methods used to survey or study wild bats, and should only be employed if a rigorous assessment concludes that the benefits of doing such work clearly outweigh the potential harm to bats. The associated capture methods are often referred to as advanced survey techniques. Again a licence is required to undertake those methods of capture.
This webpage is to provide links and information to those already ringing. If you are looking for advanced training, please see our training for ecologists or speak with your local bat group.
If you have found a ringed bat and are wondering what to do, please see our advice page.
Ringed Bat Database
A central repository of data on ringed bats is important due to the long scale nature of such studies, and increases the information that can be gained from the process. It is also in accordance with EUROBATS Resolution No. 4.6 (2003).
The scope and requirements of the UK ringed bat database have been agreed through discussion with bat ringers. For further information please refer to the bat ringing guidelines (once available).
The database will be launched in January 2025.

Bat Ringing Guidelines
Bat ringing guidelines are being drafted, in consultation with experts in the field, and will be available here in due course.
Currently guidance can be found in chapter 6 of the Bat Workers Manual (2004).
