The effect of atmospheric circulation on spring arrival of short- and long-distance migratory bird species in Estonia
The aim of this study was to analyse and identify preferred atmospheric circulation conditions for migratory birds during their spring arrival in Estonia (for Tartu and Kuressaare). A total of 47 circulation classifications and 42 common bird species were studied. The analysis identified a clear div...
