Is this little bird a willow warbler (Phylloscopus trochilus)? I think it is. Yesterday I noticed many of them flying from leaf to leaf picking insects. I wanted to get a little closer for better pictures but as soon as I took a few steps forward they all flew away. After a while they came back. I had to shoot them from a safe distance. I read that willow warblers in August-September are migrating down to central Africa. Isn´t it amazing that these tiny birds are able to fly that far ?
