The call of A. tanzanica is similar to that of A. fasciata and consists of short, 2–3 syllable echemes; each successive syllable in an echeme is successively louder than the previous one; mean syllable duration is 0.0723 s (SD=0.0137, n=11); the peak frequency of the call is 10.5–12.9 kHz (Figs. 55D–F). The call is loud and easily perceived by the human ear. In addition to the advertisement call, both males and females produce loud, broad fre- quency release calls if captured.
