Abstract: An in situ recording was conducted to study the spatial pattern of song sharing within Emberiza godlewskii population. A total of 24 individuals’ songs were recorded, averagely 34 songs each individual. Each song consisted of multi-elements, and the elements were grouped by shape and classified into seven broad categories. The song dissimilarity index was computed for each pair of the individuals, according to the usage of each element category. No significant differences were observed in the song dissimilarity index between neighbors (0.224±0.076) and non-neighbors (0.245±0.050) (T test, P=0.095), and also, there was no significant correlation between the song dissimilarity index and spatial distance (Mantel test, P=0.227). The song sharing within E. godlewskii population had no definite spatial pattern, possibly due to the excessive human disturbance on the habitat and the greater annual change of the individuals within the population.
