Crinan Jarrett, Auteur ; Marc Illa, Auteur ; Marta Burri, Auteur ; Gabriel Marcacci, Auteur ; Vanessa A. Mata, Auteur ; Maria Luisa Boglino, Auteur ; Oumnia Himmi, Auteur ; Ivan Maggini, Auteur ; Barbara Helm, AuteurData on the diets of Afro-Palearctic migratory birds outside their breeding grounds are scarce, despite the importance of feeding during the migratory journey. Here, we report on anecdotal findings from a study in which we used diet metabarcodin[...]

However, such studies can be constrained by the [...]
