Monica Retamosa is in the middle to change the battery recorder tape when she heard Bellbird for the first time. Stand up on the forest floor, he appears to the tree, scan for a south and powerful sound source, looking for the bird half an hour none of the benefits. That Bellbird singing from the treetops where you look at your friends but don’t look at the bottom. Still, retamosa smiles: They caution ecosystem in Costa Rica biological corridor by listening. He calls to attract pairs, communication identity, reminding the danger, guiding the way, and helps hunting or defending. For years, researchers have tracked the species in the hands, and still performed, thoughts grow much use of remote recording devices. The research of organisms sound is known as bioacoustics. Retamosa has done this job for 10 years, BioaCoustic study, a bird that brings out a loudly to make him hear from the cities and loud tip of the nests to coordinate the door. And when BioaCoustics is combined with other votes – as well as the sound of landscap, such as crashing waves in the sea, it is possible to interpret the deeper ecological meaning. So you can monitor biodiversity changes, detect threats, and measure the effectiveness of conservation stratens. The more widely sound sound analysis is known as Ecoocoustics-and it’s exactly the work that is done in Costa Rica.a three bellbirds (enricarincilulausus) procnias) in Costa Rica.

He uses bioacoustics and ecoacoustics for investigating the sound of the Central American country to be more than half a million species. “The sound has been forgotten from the conservation point of view,” Retamosa said. “Most of the time, we hear more than we look at. The possibility that the disorders occur in the system, we can detect quickly, or there is no other factor.” Automatic recording of BioaCustics Revolution and Ecoacoustics. Currently, research groups can hang out the sensors that note the pieces on the day for several months without intervention with wildlife. Retamosa enjoys this strategy because it is not invasion for animals, making it easier to have ears in large areas and sometimes-sometimes that can be found to find a mysterious species. The remaining distance goes to the forest to set up a record. Visits to a very good field, but never walked. He has approached a mile over the clay and branch, along with his friends Jimmy Barrantes and Randall Jiménez. She is up and down without endless. Once, he falls and sprays the ribs. But the work does not end with installation: must return to changing the battery and memory card. In other countries, use the solar panel and the Internet receives real time data; In the darkest and damp rift of Costa Rica, still performed by hand.
