From May 09 to May 12, Pierre-Lou accompanied for several days Lennart Saari on the island of Aasla.

This island located in the Archipelago of Turku welcomes in spring many species in migration or breeding. And no better than Lennart Saari knows this island because it carries out species monitoring for more than 40 years. He has identified just 100 species in 4 days, and for the majority it is by ear that he was able to recognize them!

Here are some images encountered during these days at his side. A big thank you for his welcome!
