Mate, neighbour and stranger songs: a female song sparrow perspective.
We investigated discrimination by female song sparrows Melospiza melodia, between different categories of male song using the copulation solicitation display as a preference assay. Females responded most strongly to songs recorded from their mates, less strongly to songs of neighbouring males and least strongly to songs of stranger males. Among the stranger songs, however, females preferred son...
متن کاملCultural Evolution of Puget Sound White-Crowned Sparrow Song Dialects
The songs of male Puget Sound white-crowned sparrows currently form about 12 dialects along the Pacific Northwest coast. In his survey of 1970, Baptista (Condor 1977; 79: 356–370) defined six of the dialects based on the song’s terminal trill because most males at each locality shared the simple syllables (SSs) in this trill. The complex syllables (CSs) in the song’s introduction varied among m...
متن کاملRock Sparrow Song Reflects Male Age and Reproductive Success
The evolution of mating signals is closely linked to sexual selection. Acoustic ornaments are often used as secondary sexual traits that signal the quality of the signaller. Here we show that song performance reflects age and reproductive success in the rock sparrow (Petronia petronia). In an Alpine population in south-east France, we recorded the songs of males and assessed their genetic breed...

Soha (2009), doi:10.1016/j.anbehav.2009.02.021 T E D P R O Adult male grasshopper sparrows sing two structurally and functionally distinct songs: buzz song and warble song.

متن کاملMicrogeographic Song Variation in the Nuttall’s White-crowned Sparrow’
Intradialect variation in the song of 138 male Nuttall’s White-crowned Sparrows (Zonotrichia Zeucophrys nuttalli) was examined using multivariate cluster analyses on both quantitative (frequency and temporal) and qualitative (structural) variables. Mapping of song groups revealed local song clusters with a high degree of spatial overlap and the occurrence of “satellite” males located well outsi...
