We are using satellite tracking technology to help us to understand:
- The routes taken between British wintering areas and continental breeding grounds in spring and routes back to wintering areas the following autumn.
- The details of the timing of departure from different breeding grounds and the total time taken to complete the autumn and spring migrations, including any differences between adults and juveniles.
- The details of stop-over locations and durations.
- Fidelity of individual birds to particular migration routes and winter sites.
