Strategies of migration and wintering of Italian lesser kestrel Falco naumanni populations.
Avian migration is naturally a plastic trait, and tracking migratory birds is problematic because of distances and areas involved. Electronic data loggers (e.g. light-level geolocators, GPS/GSM tags, etc) provide a means to directly follow several individuals and understand migration routes and geographic patterns of population displacements in overwintering areas. Thanks to the collaboration between different projects (PRIN, LIFE+ LIFE11/NAT/IT068), we tracked lesser kestrels equipped with GPS/UHF and GLS devices and we analyzed the migration data of more than 20 individuals breeding in different populations of Sicily (Gela Plain) and Southern Italy (Altamura, Gravina). The weights of comp…
Chapter 24. Lesser kestrel Falco naumanni
The lesser kestrel is a small colonial falcon with a broad breeding distribution range, extending from the Iberian Peninsula to eastern China. Most of the biological and ecological knowledge concerning this species, including migration, has been obtained from European populations. After the end of each breeding season, these populations move preferentially northward, showing pre-migratory movements (of 100–1,000 km) that are necessary to reach rich foraging grounds where they can fuel before commencing the true migration towards Africa. European lesser kestrels migrate on a broad front across the Mediterranean Sea. There is a strong connectivity between European breeding and African non-bre…
