Local competitive environment and male condition influence within-bout calling patterns in túngara frogs

The data is made up of acoustic parameters for calls of wild tungara frog males calling in choruses of various sizes. Entire call bouts were recorded (using WM-D6C Sony tape recorder and a Sennheiser ME-66 shotgun microphone) for 24 males from beginning to end, and were then processed with SIGNAL (http://www.engdes.com/) to extract amplitude and spectral charactersitics for every call for that bout. Additionally, the number of males calling within 1m of the recorded focal male, the snout-vent-length and weight of the focal male, and air and water temperature where the focal male was calling were all recorded.
