Calling strategies of male túngara frogs in response to dynamic playback

摘要: Tungara frogs produce calls of varying complexity that consist a whine followed by 0–7 chucks. In previous studies using static playbacks, males increase chuck number in response to with 1 versus 0 chucks but not 2 or 3 chuck. Here we use dynamic playback which an automated interaction program counts the present call and responds according specified calling strategy determines call. Males added progressively more models' strategies de-escalate, match escalate; there was significant difference focal males' responses de-escalate escalate strategies. Similarly, changed their model. There no evidence change patterns, as estimated entropy, among treatments between experimental field data. produced significantly these experiments than field, both contexts mean is low never approaches maximum observed nature. These data suggest are cost-sensitive when it comes adding they influenced vocal competitors rather patterns previously revealed this study another demonstration usefulness animal communication.
