To find out how wildlife is doing, scientists try listening

BERLIN, Oct 22 — A reedy pipe and a high-pitched trill duet against the backdrop of a low-pitched insect drone. Their symphony is the sound of a forest, and is monitored by scientists to gauge biodiversity.

Jorg Muller, a professor and field ornithologist at University of Wurzburg Biocentre, wondered if there was a different way. Muller and his team recorded audio at sites in Ecuador’s Choco region ranging from recently abandoned cacao plantations and pastures, to agricultural land recovering from use, to old-growth forests.Then, they carried out an acoustic index analysis, which gives a measure of biodiversity based on broad metrics from a soundscape, like volume and frequency of noises.

While the library of available sounds to train the AI model meant it could only identify a quarter of the bird calls the experts could, it was still able to correctly gauge biodiversity levels in each location, the study said.
