The Short-toed Eagle Circaetus gallicus has a wide

breeding distribution in the Palearctic region and in NW Africa, and spends the winter in the Sahel (Cramp & Simmons 1980). The Iberian Peninsula, with 2000– 2772 pairs, holds half of the European breeding popu-lation (Mañosa 2003). Several migratory raptor species in the Palearctic-Afrotropical migratory flyway, includ-ing the Short-toed Eagle, are in steep decline in their Sahelian wintering areas (Thiollay 2006). The lack of information on migratory pathways, stopover sites (if any), pre- and post-migratory behaviour and habitat use during migration and wintering prevent the identi-fication of bottlenecks in the life cycle of Short-toed Eagles. In recent decades, the use of satellite transmitters in monitoring birds has enabled the collection of accurate information about long-distance journeys of migrating raptors, including timing, speed, daily activity and win-tering sites. GPS satellite tracking allows high precision in delineating migration routes and stopover sites (Meyburg & Fuller 2007). Here, we report the autumn migration of two juve-nile Short-toed Eagles tracked by GPS satellite teleme-try from their natal area in the Iberian Peninsula to their wintering grounds in West Africa. We also provide information on timing and speed of migration. The only previous tracking studies on Short-toed Eagles in-volved an adult (Meyburg et al. 1998) and an immatur
