Variations dialectales des sifflements de l'étourneau sansonnet sédentaire en Bretagne
Abstract
On the basis of data acquired during a preliminary study, dialects were examined for four specific whistle themes in an area of 50 × 35 km. The use of a quantitative method to compare sonograms permitted distinguishing different variants for each theme. These were not distributed at random, but determined dialect zones which covered different areas for each theme. The zones corresponding to the different whistle types were not concentric.
