Principles of the analysis of structure of chaffinch song (<i>Fringilla coelebs</i> L.). Individual variability of song

Abstract

Song of birds is subtle and flexible species specific feature, like as the morphology signs. Species specific song of chaffinch (<i>Fringilla coelebs</i> L.) can be judged as precise character in the image on sonograms. The song has the certain structure and shares (divides) on the parts, elements, which consists of them. Individual variability of songs of one type will consist in unique singing each of chaffinch males, who form a local population
