There is much scope in combining Earth observations with Down-to-Earth observations of tracked #shorebirds. We developed a very satisfactory LAND USE INTENSITY metric based on @Sentinel1a explaining godwit distributions. besjournals.onlinelibrary.wiley.com/doi/full/10.11… @ESA_EO @esa

We were able to show the value of both this new LAND USE INTENSITY metric as well as distribution of tagged godwits during hot dry summer of 2018, when much of what is now evergreen pasture turned brown. #climatechange #Dairy @RuthHowison @DairyCampus

Distribution of tagged black-tailed #godwits in early summer was better predictor of #drought damage than land use intensity. Interpretation: #grutto's select intact #soils with capillary connections with #groundwater. #meadowbirds #sentinels @WaderStudy

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

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
