Flicker call in normal time then followed by same call slowed to 0.092x found at 12.3 seconds.
Dettagli dell'osservazione
A polyphonic call made up of what appears to be three components beginning with component #1, a mostly monophonic whistle followed by #2, a shorter monophonic whistle at lower frequency. #3, a down slur at yet a lower frequency...all components seem to have their respective multiple integer harmonics. The image is of a Raven Lite spectrogram with the numbered components showing overlapping(polyphony). Audio #2 begins with call in real time followed by same call slowed to 0.092x to hear the individual components and temporal overlapping...an example of bird virtuosity.
