| 1 | So much for the city:Urban–rural song variation in a widespread Asiatic songbird显示文摘Song plays a fundamental role in intraspecific communication in songbirds.The temporal and structural components of songs can vary in different habitats.These include urban habitats where anthropogenic sounds and alteration of habitat structure can significantly affect songbird vocal behavior.Urban-rural variations in song complexity,song length and syllable rate are not fully understood.In this study,using the oriental magpie-robin(Copsychus saularis)as a model,we investigated urban-rural variation in song complexity,song length,syllable rate,syllable length and inter-syllable interval.Comparing urban and rural songs from 7 countries across its natural Asiatic range(Bangladesh,India,Malaysia,Nepal,Singapore,Sri Lanka and Thailand),we found no significant differences in oriental magpie-robin song complexity.However,we found significant differences in temporal song variables between urban and rural sites.Longer songs and inter-syllable intervals in addition to slower syllable rates within urban sites contributed the most to this variance.This indicates that the urban environment may have driven production of longer and slower songs to maximize efficient transmission of important song information in urban habitats. | Samuel D.HILL Achyut ARYAL Matthew D.M.PAWLEY Weihong JI | 2018 | Integrative Zoology2018，13，2： | 0 |
