BTO has a long history of working on migrants, from the first use of bird rings to look at the movements of birds. Our current work on long-distance migratory species covers two complementary approaches:
- the deployment of new tracking devices to understand the ecology, movements and non-breeding locations of individuals from breeding populations, many of which are declining
- analyses of long-term monitoring data, including from bespoke surveys, the Ringing and Nest Record Schemes, to identify drivers of population change
