Studying migration and bird movements through coordinated ringing and recovery across Mongolia.
Bird ringing is one of the most effective ways to study migration routes, survival and site fidelity. The MOS Bird Ringing Center coordinates licensed ringers, manages the national ring series and compiles recovery data.
Ringing is carried out under licence, following national and international standards. Each ring carries a unique number and the country code, allowing birds to be traced anywhere on their migration route.
Data collected at ringing stations contributes to the East Asian–Australasian Flyway partnership and to global migration research.
