The location of Egypt gives us an unique opportunity to study birds in one of the most important and still poorly known migration routes between Eurasia and Africa. Preliminary results of our work show a complex pattern of the Reed Warbler migration in Egypt. Birds were caught in autumn and spring, in different years between 2001 and 2007, at six SEEN stations in Egypt, located on the Mediterranean Sea coast (Burullus), on the Red Sea coast (Sharm El Sheikh, Hurghada and Wadi Gemal), on the edge of the Sahara desert (Wadi El Rayan) and in the Nile Valley (Saluga Ghazal). The migration of Reed Warbler in Egypt is more intensive in spring. The highest numbers of Reed Warblers per day in both seasons were caught at Hurghada, which may indicate an important migration route along the Red Sea coast. Wing length distribution of birds from Burullus differs significantly from similar distributions at the other stations, which may suggest migration of different populations through this region. A comparison of fat score between the northern and southern stations in Egypt shows an influence of geographical barriers on fattening of Reed Warblers and may indicate different migration routes in autumn and spring.
