摘要

Results of the first spring migration count of soaring birds at Ayn Sokhna, 60 km south of Suez on the west coast of the gulf of Suez, are presented. Significant numbers of raptors can be observed from this one observation site throughout the migration season regardless of each day's wind direction and speed. Observations were recorded 5 hours daily 1 March-2 May 2012. A total of 183 275 migratory soaring birds were identified and counted, of which 154 276 were raptors (18 985 eagles), and 28 999 were storks, pelicans and cranes.
