Data from: ‘Same procedure as last year?' Repeatedly tracked swifts show individual consistency in migration pattern in successive years
Individual migration pattern during non-breeding season is still a black box in many migratory birds. However, knowledge on both individual level and population level in migration and overwintering is fundamental to understand the life cycle of these birds and the constraints affecting them. We show...

Individual migration pattern during non-breeding season is still a black box in many migratory birds.

In contrast, different individuals from the same breeding colony showed diverse movement patterns during non-breeding season suggesting that several suitable areas for overwintering coexist.
