Spectrograms of banded mongoose close calls. Spectrograms of close calls of the three individuals (in rows 1 to 3) associated with the three different behavioral contexts: a.) digging; b.) searching; c.) moving between foraging patches. The calls in the first and second row are of females, while calls in the third row are of a male. Calls of the individuals in the second and third row are from the same social pack. The solid black arrows indicate the individually stable foundation of the call, while the dashed arrows indicate the harmonic tonal segment (Hamming, FTT = 1024, overlap = 97.87%, frequency resolution = 43 h).
