At the beginning of May, Pierre-Lou participated in various field missions alongside several teams of researchers from the University of Turku.
On the island of Ruissalo, he accompanied the team of Suvi Ruuskanen and Antoine Stier to carry out monitoring and studies on breeding passerines, especially Great Tit (Parus major) and Pied Flycatcher (Ficedula hypoleuca).
Then, he accompanied Céline Arzel and her team on the site of Evo, located further north, to set up invertebrate traps in different lakes in the study area and carry out bird survey on these same lakes. These works aims to study some factors that affect waterbird populations.
