Etude des réseaux de communications acoustiques chez un oiseau chanteur forestier, le Troglodyte mignon (Troglodytes troglodytes)

Abstract : The Winter wren is a forest songbird singing discrete songs for territorial defense and mate attraction. Neighbouring males defending adjacent territories form acoustic communication networks. Little is known about such networks concerning their onset, dynamics and evolution in time, under natural conditions.By means of focal and continuous recordings, a survey over several years, acoustic analyses as well as propagation and playback experiments, we showed that: i) songs follow complex syntactical rules and form microdialects, ii) neighbouring males share many songs and discriminate between songs from neighbours and strangers, iii) males have complex individual acoustic signatures and use differential singing strategies in interaction with each other, iv) groups of neighbours are perennial communities maintaining vocal traditions.
