Stoked to announce @ZooKeys_Journal published our @BatumiRaptors data paper! It explains how our #citizenscience project monitors the autumn #migration of >1.000.000 #raptors in the Eastern Black Sea Flyway, and how to use our #openaccess data @GBIF/@NLBIF! - 1/n

#ornithology
Many #raptors migrate primarily by thermal #soaring. To do so they travel by day and avoid high mtns and open sea. This leads to spectacular raptor aggregations in overland #flyways. One of the world´s largest raptor flyways occurs along the eastern Black Sea coast in SW Georgia.
The Eastern Black Sea Flyway has its narrowest point just north of #Batumi, where the coast and Lesser Caucasus form a clear "bottleneck". The mtns are not extremely high but present a significant barrier for #raptors on #migration due to low and dense cloud cover. @BatumiRaptors
