Migratory connectivity describes the linkage between breeding and nonbreeding sites, having major ecological implications in birds: 1 season influence the success of an individual or a population in the following season. Most studies on migratory connectivity have used large-scale approaches, often considering regional populations, but fine-scale studies are also necessary to understand colony connectivity. The lesser kestrel , an insectivorous migratory raptor which form colonies during the breeding period, was considered to have strong connectivity based on regional populations.

- External factors, particularly geography and weather, have a significant impact on the migration patterns of lesser kestrels, affecting daily travel times and flight speeds.
- The study utilized GPS tracking on 70 lesser kestrels to analyze how external (wind, geography) and internal (sex) factors influence variations in their migration behavior.
- Findings revealed that geography and tailwinds primarily dictate travel schedules, with wind accounting for most seasonal differences, indicating that external factors are more crucial than internal ones in shaping migratory behavior.
