I have been seeing single House Martins around dusk for several days now in Mitilini town. I had my first real flock of 9 flying in and out of their nests in Skala Polichnitos port on March 3.
The very first House Martin of this Spring was seen in Pamfila village (north of Mitilini) on February 20 (by Eleftheria Pavli) and the very first in mainland Greece were reported from Athens on February 17 (by Panagiotis Latsoudis).
