The Batumi bottleneck lies in the western coastal part of the trans-Caucasian migration corridor for soaring birds (main map, based on Abuladze 2013) and holds the strongest passage of migrant raptors at the eastern Black Sea flyway. The two hilltop count stations (red dots) are in the foothills of the Lesser Caucasus close to the city of Batumi in southwestern Georgia (inset).
