Sonographic analysis of conspecific advertisement calls of yellow-breasted bunting (Emberiza aureola) was carried out. Calls of nine individuals living in the same range were compared. Particular elements responsible for individual differences were recognized in the calls. At the same time, the elements defining conspecific characters were recognized in all individuals. Individual differences were based on temporal indices: durations of individual syllables and intervals and even fusion of two syllables.
