ABSTRACT: When studying song
organizations of chaffinch (Fringilla coelebs L.), we find the unique
typological parities (ratio) of songs in different local populations of a
species-specific area. 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.
