Lesser kestrels of the same colony do not overwinter together.

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.

Striking Variability in the Post-Reproductive Movements of Spanish Red Kites (): Three Strategies, Sex Differences, and Changes over Time.

It was assumed that the Spanish breeding population of the red kite () was resident, hence their movements were restricted to their breeding area for their entire lifecycle. However, recent observations indicated that the post-reproductive strategies of the red kite in Spain are more diverse. We tagged 47 breeding adult red kites in Spain and analyzed their movements during the post-reproductive period (July-February).

The variability of juvenile dispersal in an opportunistic raptor.

The juvenile dispersal of raptors is a crucial stage that stretches from parental independence to the establishment of the first breeding area. Between 2012 and 2020, 44 juvenile red kites from the Spanish breeding population were tagged using GPS telemetry to study their dispersal. Juveniles left the parental breeding area at the end of their first summer and performed wandering movements throughout the Iberian Peninsula, returning to the parental breeding area the following year, repeating the same pattern until they settled in their first breeding area.
