Honey Buzzard migration, Batumi 2013-09-03
A short film of migrating Honey Buzzards in Batumi. The bottleneck of Batumi is probably one of the best places to be if you wanna see a lot of migrating raptors. In early september, the peak time of honey buzzards occurs and thousands of Honey Buzzards migrate.
However, there are always other days, better than good days.

Much has been written about the Batumi Bottleneck in Georgia and its importance for migrating birds. So it’s great to hear that its protection is valued and will continue, thanks to the Whitley Fund for Nature and the Society for Nature Conservation in Georgia (SABUKO)</a: here.
