Abstract: | The song repertoire of many sparrow species (Passeriformes) has not one but several song types. In the investigated chaffinch
population (Fringilla coelebs L.), we revealed 22 types of songs, of which four turned out to be rare (they were found in 1—2 points), and five song types
were combined (they consisted of phrases of different song types). The average size of the chaffinch repertoire in the Curonian
Spit was represented by 2—3 song types (max of 6 song types and min of 1 song type). The variation in song types considered
by us can speak for genetic heterogeneity. |
