Background: Turkey, is one the primary migration bottlenecks in Europe for soaring birds. On the western part of Turkey, on the other hand, the movement of migration mainly takes place in two bottlenecks where water masses are the narrowest (Bosphorus, Gallipoli Peninsula-Dardanelles). According to bosphorus, there is a limited number of migration monitoring studies in Gallipoli Peninsula (Dardanelles). Objectives: The aim of our study is to monitor the migration movements of the Gallipoli peninsula (Dardanelles) in spring and autumn and to evaluate the relationship between wind intensity and direction of migration intensity. Methods: Raptor migratory birds were observed during the spring and autumn migration period from 5 point determined on the Gallipoli peninsula 2015. in A total of 45 days of land work was conducted, 19 days in the autumn migration period (11 August-18 October) and 26 days in the spring migration period (12 March-11 May). Counts were performed following the method described by Bird & Bildstein (2007). Results: We observed 5296 raptor belonging to 22 species during spring migration period and 3061 raptor belonging to 20 species during autumn migration period in the field studies. There is a positive (0.464) linear relationship between the number of individuals observed in the spring migration period and the wind speed (t: 8.089, p: 0.000). 66.6% of the passages were observed at wind speeds above 20 km / h and 88.5% were observed in the days when the northern winds dominated. In the autumn migration period, there was no significant relationship between wind speed and number of individuals. It was observed that 69.6% of the passages occurred on days when the northern winds were dominant. Conclusions: The present study, in 2015, carried out a reasonably complete census of the raptor birds passing over the Gallipoli peninsula, one of the important migration routes in the western palearctic region. In this study, it was determined that there is much less passage in the Gallipoli peninsula than in the Bosphorus. But it was observed that the number of passes increased in the days when strong winds from north and northeastern dominated.
