Bat rings

Rings of suitable size for bats. Putting uniquely numbered rings on wild bats to identify individuals is a long established technique associated with important bat research and monitoring. The rings are made from very light materials, and are designed to have no adverse effect on the bats.

Round lipped rings are open – ready to put on bat’s arm. The edges of the rings are blunt. Rings are packed on plastic tubes.
