ROJAS-MORALES, Julián A.; LA MARCA, Enrique  and  RAMIREZ-CHAVES, Héctor E.. Advertisement call of a population of the nurse frog Leucostethus fraterdanieli (Anura: Dendrobatidae), with notes on its natural history. Biota colombiana [online]. 2021, vol.22, n.1, pp.122-132.

We describe the advertisement call of seven males and observations on the natural history related to the parental attention by males, of a population of nurse frogs attributed to the Leucostethus fraterdanieli complex from the Central Cordillera in the Department of Caldas, Colombia. The advertisement call consists of a long sequence of repeated (x̅ = 143 notes.min-1) pulsed notes, which have an average duration of 79 ± 17 ms (range 63-122 ms), separated by time intervals between 187-413 ms (289 ± 67 ms). The dominant frequency values are in the range between 3209-3520 Hz. Our results suggest differences in temporal and spectral parameters between the population studied and other populations assigned to L. fraterdanieli, L. brachistriatus, and the recently described L. jota.
