Abstract

The deployment of autonomous recoding devices has enabled behavioral biologists, conservation biologists, and ecologists to address a host of scientific questions including problems which were impractical or impossible without such devices. By adding the ability to spatially locate the source of vocalizations, a host of new possibilities have been opened. We have developed self-localizing field-deployable acoustic sensors that can coordinate to detect, record, localize, and enhance animal calls and bird songs. Ongoing improvements focus on making the system more robust and easy to use, as well as improving detection and localization algorithms using a paradigm which includes inter-node collaboration.
