Cicadivetta goumenissa Gogala, Drosopoulos & Trilar 2012
High frequency song of Cicadivetta goumenissa - typical sequence from a song, which can last about the minute with many repetitions
The same song sequence of Cicadivetta goumenissa sp. nova with reduced frequency to 50% for old ears
During the song the duration of long echemes sometimes increases and the number of short echemes inbetween decreases
Again carrier frequency of the same selection reduced to 50%!
At the end of a song there are usually longer sequences of short echemes and the song dies out or is again repeated with the pattern shown in the first two samples.
Carrier frequency of the same selection reduced to 50%!
