Willow Warbler | Fitis (-Laubsänger) | Phylloscopus trochilus - Helgoland, September 2020

This Willow Warbler probably came somewhere from Scandinavia and will travel towards Sub-Saharan Africa.  Despite their very small size and weight of less than 10 gramms, they are long-distance migrants and even populations from eastern Siberia go to sub-Saharan Africa, migration through the Asian continent.
