Geographic Variation in the Organization of Song Sparrow Repertoires
—We asked whether geographic variation exists in the complexity of song repertoires in Song Sparrows (Melospiza melodia) by quantitatively comparing four measures of repertoire organization across four geographically distant populations: (1) repertoire size (the number of distinct song types), (2) the number of ‘‘minimal units of production’’ per repertoire, (3) mean similarity among variants o...
متن کاملSong development in the grasshopper sparrow, Ammodramus savannarum
Please cite this article in press as: Jill A. 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. To investigate how these songs develop, we tutored three groups of young males in the laboratory: one with recordings, one with live adult tutors and one with no song (isolate bi...
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...
متن کاملSocial influences during song development in the song sparrow: a laboratory experiment simulating field conditions.
Oscine songbirds are exposed to many more songs than they keep for their final song repertoire and little is known about how a bird selects the particular song(s) to sing as an adult. We simulated in the laboratory the key variables of the natural song learning environment and examined the song selection process in nine hand-reared male song sparrows, Melospiza melodia, a species in which males...
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...
