Deep in the emerald cloud forests of Cusuco National Park of Honduras, scientists are on a quest to record the never-before-heard call of the endangered “exquisite spike-thumb frog” (Plectrohyla exquisita). This charming ambassador for the park’s rich biodiversity is just one of 16 different species of amphibians listed as Endangered or Critically Endangered by the IUCN that are clinging to survival inside the small park. Some are found nowhere else on Earth.
The exquisita’s mating call, if found, might inspire frogs at the Honduras Amphibian Rescue & Conservation Center (HARCC) to breed in captivity, an important step in protecting the endangered species. But how can we find and record this call when we don’t know what it sounds like? And how can it be recorded clearly in the middle of a bubbling river?
In the bioGraphic video above, herpetologist and conservationist Jonathan Kolby teams up with sound artist Ben Mirin to record the exquisite spike-thumb frog mating call. We also see and hear some beautifully filmed moments with other small creatures in the landscape.
