Species specific song of chaffinch (Fringilla coelebs 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.展开更多

Probably, these opposites process as if other qualities of different forms of energy also create “movement” development. Thus the given properties of a matter of the nature can be considered at different levels of its organization. The singing of many passerine birds is incontrovertible feature of their life which determines and builds a reproductive cycle. By studying song repertoire of many sparrow species in details, it was revealed that the individual has not only one, but some types of songs. Thus spring singing represents the multifunctional phenomenon and can bear (carry) various values. The singing is not only a means of attracting females, but also a means of intimidation of the contender and delimitation of nested territory. Variants or types of species-specific song are individually various and distributed between individuals of a population. The complex interrelation of geographical variability of chaffinch song in many respects gives a support at an evolutionary view in the given aspect.展开更多

The degree of prevalence of different chaffinch song types can’t correspond to percentage proceeding from their general (common) number in a population. Thus different areas of Russia are forming original (different) song cultures of chaffinch, consisting of the certain set and a parity (ratio) of song types, frequently including the so-called dialect song forms, that have been observed. The complex interrelation of geographical variability and structural variability of chaffinch song in many respects gives a support in an evolutionary view from the given aspect.展开更多
