Even birds speak different dialects : How different are they?
Birdsong is known to be variable geographically in many species, and we have anecdotally observed this effect in Wyoming populations of the House Wren (Troglodytes aedon). This variation may be due to gradual divergence in song dialects between geographically distinct breeding populations, genetic variation among populations, or habitat-driven differentiation based on sound transmission properties of the environment. In this project, we collected 944 wren calls from three different locations around Wyoming, tested the similarity of various acoustic environments and modeled call similarity against ...
