Résumé :	From 1989 to 1997, 449 broods of Kestrels were monitored and 1669 nestlings ringed. All breeding activity took place in nest boxes attached to buildings. The average clutch size was 5.15 eggs, the average number of hatchlings 4.81 per clutch. Most common are clutches of 5 eggs, as well as 5 nestlings. Among 417 successful nests, one was observed with 8 fledglings. Almost 60 % of recoveries are from tagged birds in their first year. The oldest Kestrel recovered so far was 7 years old. The main migratory route lies in the direction west to south. To date, the remotest recovery ever reported comes from Algeria in February, at a distance of 1475 km.
