Song repertoire size predicts initial mating success in male song sparrows, Melospiza melodia
Male song sparrows sing repertoires of 4–13 distinct song types and have proved a valuable model for testing hypotheses concerning the function and evolution of song complexity. Captive female song sparrows solicit more copulations in response to playback of larger repertoires, yet it remains unclear whether male repertoire size influences female mate choice in natural situations. We used long-...
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 کاملSong sharing correlates with social but not extrapair mating success in the white-crowned sparrow
Bird song is a prominent example of a trait under interand intrasexual selection. Performance-related aspects of bird song have been shown to vary among males and to influence territorial interactions as well as female mate choice. In oscine songbirds, song is different from many other sexually selected traits in that it is learned. As a result of learning, territorial neighbors share songs in ...
متن کاملSong-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 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...
