Ameerega panguana Brown et al, 2019

The advertisement call for A. panguana (Table 1, Figs. 5 & 6) is a short ‘peep’ repeated 1.1–1.9 times per second for several minutes. Each note is short (mean 0.23 s), with the dominant frequency from 4.9–5.5 kHz. This single-note advertisement call is given most frequently in the afternoon and evening as males chorus in small groups. We also note a second call type in A. panguana of two to three notes in quick succession (within 10 ms of each other), repeated once every 3-90 seconds. The latter call appears to function as an aggressive or territorial call and is most frequently heard in the early morning and early evening (Schlüter 1980). [1]
