  • Title: Songbird dialects
  • Short description:

    Quantification of similarity between complex songs recorded in noisy environments in the wild is a substantial challenge. Therefore, the goal of this project is to improve existing quantitative methods for assessing similarity between the songs of Spiza americana. The project is a collaboration with Timothy Parker, Dept of Biology, Whitham College, Walla Walla, USA

    Prerequisites: FMSF10/MASC04, (FMSN35/MASM26)

  • Long description:

    Many songbird species have geographically structured vocal culture in which individuals at a location produce songs similar to each other that clearly differ from songs produced at other locations by members of the same species.  Scientific study of such vocal culture is facilitated by reliable quantification of the similarity between pairs of songs. However, quantification of similarity between complex songs recorded in noisy environments in the wild is a substantial challenge. For instance, in the North American bird Spiza americana, human observers can still readily outperform existing quantitative methods in assessing the similarity between songs. Therefore, the goal of this project is to improve existing quantitative methods for assessing similarity between the songs of Spiza americana. The project is a collaboration with Timothy Parker, Dept of Biology, Whitham College, Walla Walla, USA.
