Résumé :	During the second half of September 2000, observations were made of the autumn migration of Marsh Harriers (Circus aeruginosus) in three locations in the central Mediterranean: the Circeo promontory (Central Italy), Malta, and Marettimo Island (Western Sicily). In total, 973 Marsh Harriers were recorded (416 from over Malta). In the Circeo promontory, the Marsh Harriers did not follow the coast, but rather flew southward in the direction of the Poinziane Islands over the Tyrrhenian Sea. For each of the three observation sites, respectively, the number of observed Marsh Harriers per day and the itemization of the birds according to age and sex were compared. No relationship was evident between the observations in the Circeo promontory and the islands of Marettimo and Malta. The findings make it possible to assume that the Marsh Harriers in the central Mediterranean migrate on a broad front in a direction from the northeast to the southwest.
