Variación individual e indicios de variación geográfica en el canto territorial del chucao (Scelorchilus rubecula) en el centro-sur de Chile

Abstract

We evaluated the individual and geographic variation in the territorial songs of five populations of Scelorchilus rubecula. The results suggest individually consistency in songs and vocal variation among individuals of S. rubecula. This high consistency of individual songs (66 – 91 %) indicates that some variables (i.e., duration of phrase 1, FMA beginning phrase 1 and FMA end phrase 2) of S. rubecula territorial song can be used for individual identification. While a geographical/population-level analysis showed no clear structured pattern.
