Ewa Węgrzyn, Auteur ; Konrad Leniowski, Auteur ; Tomasz S. Osiejuk, AuteurWe analyzed a set of frequency and temporal characteristics of the introductory syllables in the song of the Great Reed Warbler (Acrocephalus arundinaceus) to assess their potential for individual recognition. We also tested if the initial sylla[...]
