The advertisement call of Pristimantis subsigillatus (Anura, Craugastoridae)

Abstract:

We describe for the first time the advertisement call of Pristimantis subsigillatus from southern Ecuador. Our study provides a detailed quantitative characterization of the advertisement call of P. subsigillatus, filling a gap in our knowledge of this genus, the most speciose among vertebrates. Males called perched on vegetation 0.5-2.5 m above ground, always during mild rain. The advertisement call is composed of a single note with a duration of 63-80 ms, with an initial short pulse (3-10 ms) followed by a longer tonal component. Call rates ranged between 4-12 calls/ min. The dominant frequency varied between 2.02-2.82 kHz.
