Release calls of Pelobates varaldii Pasteur and Bons (1959) are described quantitatively based on airborne recordings obtained from 4 males and 12 females from a population of the extreme north of its range. The calls are sequences of pulsed notes with a variable number of pulses per note. To the best of our knowledge this is the first report on the acoustic repertoire of this endemic endangered species from Morocco.
