More than 800.000 raptors of ca. 30 species migrating over Batumi every autumn. Ten species observed in numbers constituting >1% of their world population (see Results & Prospects
). Several others in (one of) the highest concentration known to ornithologists anywhere in the world. The list of arguments to show the importance of the Batumi bottleneck in an international context is quite impressive. So for the casual observer, the need for implementing a long-term monitoring of migratory raptors at the eastern Black Sea seems clear.
