Altihoratosphaga montivaga
In the acoustic repertoire of A. montivaga, the combination AB is also the most distinctive verse type. However, in our recordings it was never found to be isolated, but was always preceded by several (mostly two) A elements, with increasing amplitude (Fig. 3). This complete final verse (A + A + AB) is usually preceded by a series of often three, rarely up to 15, softer verses, consisting of A elements only or additionally with an abbreviated B element (one or two impulses only), separated from each other and from the final verse by intervals of around 10–20 s. Rarely, other final structures such as A + AB or A + A + AB + AB were observed (N= 81 final verses in 90-min recording time). The structure of both elements was the same as in A. hanangensis sp. nov., with between six and eight single impulses or impulse groups in element B. Differences in the duration of both parts may be at least partly related to temperature differences. [1]
