The call of E. parkeri is divided into two distinct acoustic elements. The first part of the call is a single, prolonged syllable that is produced by dragging the nearly entire length of the stridulatory file across the scraper; the mean duration of the long syllable is 0.106 s (SD=0.0094, n=21) and the syllable contains 70–79 indi- vidual tooth strikes. The second part of the call consists of a much shorter syllable lasting on average only 0.026 s (SD=0.00236, n=88) and containing 32–44 individual tooth strikes, followed immediately by a single impulse, most likely produced by dragging only 1–3 teeth over the scraper. The peak frequency of the call is 8.7–14.0 kHz (Figs. 56D–F) and the call is easily heard from a distance of a few meters. [1]
