Examples of each vocal exchange type, excluding independent vocalizations.
Panel A: series of type E calls; Panel B: bout containing a type E call (B1), a potential call from another whale (B2)—note the difference in energy appearance on the spectrogram when compared to B1 and B3, and a second sound type (B3) believed to belong to Eistla as it has similar energy to B1; Pan...

Summary: | Panel A: series of type E calls; Panel B: bout containing a type E call (B1), a potential call from another whale (B2)—note the difference in energy appearance on the spectrogram when compared to B1 and B3, and a second sound type (B3) believed to belong to Eistla as it has similar energy to B1; Panel C: a call and response exchange between type C (C1 and C3) and type E (C2). Spectrogram parameters: DFT size 512, 256 sample hop size, and Hann window 512 samples. |
