Natural history. Very little is known about the natural history of this species, although it is assumed to be similar in many aspects to congeners, particularly to the sister species, P. garrulus , which also occurs in a similar climatic setting. So far, calls have only been recorded during late October, during the austral spring (recordings in this manuscript; Rebelo et al. 2018 ). The breeding period is expected to last for at least 2–3 months, as in the closely related P. garrulus and P. adamanteus sp. nov. As in several other species, they call from their burrow entrances in exposed or partially concealed locations ( Rebelo et al. 2018 ).
Advertisement call · Plazi
Advertisement call. The advertisement call (Figs 3 , 20 B ) consists of 5.8 notes (range 5–6) uttered in rapid succession, with a note rate of 6.68s - 1 (range 5.10–7.54). Note duration is short, 21 ms (range 21–22), and highly regular, with note 1 duration deviance 6 % (range 1–19 %). Inter-note intervals are short (117 ms, range 107–169 ms) and regular, although the last interval can be slightly longer; inter-note interval range 29 % (range 13–55 %). Call density moderately low (0.18, range 0.17–0.20). Call duration shortest of all species, only 0.82s . The basal frequency was inestimable within our sample set, with the dominant frequency at 4.4 kHz (range 4.2–4.5 kHz); a very slight lower peak frequency band may present around 1.3 kHz. Frequency appears to remain constant throughout the short note. The (human) perceived pitch tends to be higher than that of most other species. Bandwidth (90 %) is difficult to estimate consistently with the recordings available. During peak chorus activity, this species appears to call much more frequently than most other species (although sample size is small), the call period being a very short 9 seconds. The typical period of calling activity in a day is not known, but the analysed calls (during full chorus) were recorded 20–40 minutes after sunset.
