Song-type matching between neighbouring song sparrows.
In our study population, neighbouring song sparrows typically share two or more of their 6-10 song types. In an earlier experiment, we found that established neighbours typically reply to playback of neighbour-shared song with a different song they share with that neighbour ('repertoire matching'), rather than with the same song ('type matching') or with a nonshared song. In the present experim...
متن کاملLate song learning in song sparrows
In many oscine species, young males learn songs that match those of their first breeding-season neighbours. Because sharing songs with neighbours may be advantageous, selection should favour birds that retain the capacity to memorize new songs later in their first year as the birds cannot know for sure who their neighbours will be until spring. We investigated whether song sparrows, Melospiza m...
متن کاملDiscrimination of song types and variants in song sparrows
Male song sparrows,Melospiza melodia, sing highly variable songs. Traditionally, researchers have partitioned this variability by assigning songs to discrete categories termed ‘song types’, but researchers also have recognized that songs classified as the same song type are themselves variable. Territorial playbacks were used in a habituation/recovery design to investigate whether songs sparrow...
متن کاملPhonology and Geographic Song Discrimination in Song Sparrows
We investigated whether song sparrows discriminate foreign from local songs using specific phonologic markers, a mechanism of geographic discrimination previously described for some other songbirds. Song sparrows from Linesville, Pennsylvania (PA) respond more strongly to local songs than to songs from Millbrook, New York (NY). We identify 61 note categories in PA and NY songs, of which 13 are ...
متن کاملRepertoire matching between neighbouring song sparrows
A male song sparrow,Melospiza melodia, has a song repertoire of about eight or nine distinct song types, and he typically shares several of these song types with each of his several neighbours. In the prevailing theoretical view, the song types in a bird’s repertoire are interchangeable and multiple song types exist primarily to provide diversity. The present study was designed to test a contra...
