Ameerega imasmari
Behaviour:
The advertisement call for A. imasmari (Figs. 5 & 6) is a short ‘peep’ repeated 2.1–2.6 times per second for several minutes. Each note is short (mean of 0.17 s), with the dominant frequency from 4.3–4.5 kHz. This single-note advertisement call is given most frequently in the afternoon and evening as males chorus in small groups. We also observed a second call type in A. imasmari consisting of three to four notes, occasionally two notes in quick succession (separated by a mean of 13 ms, of silence), repeated once every 2-30 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]
