Their call gives this group of frogs their common name. The call is a loud, piercing "co-ki" (spelled "co-qui" by the spanish speaking people of Puerto Rico).
This group of Coqui were recorded on the southern slopes of El Yunque along the Rio Blanco.
This next individual was recorded outside our hotel room at Casa Cubuy on the southern slopes of the El Yunque National Forest. In this recording, we hear the Coqui add an extra syllable to the call, making a "co-qui-qui" call.
