Acoustic Monitoring of Threatened and Endangered Species in Inaccessible Areas

Abstract

This project developed acoustical systems for monitoring of wildlife sounds over large areas where access is limited. These systems were tested at Fort Hood, Texas, where Golden-cheeked Warblers and Black-capped Vireos are managed intensively. A balloon system was designed to carry digital audio recorders across inaccessible areas. Horn-loaded microphones were developed to provide lightweight acoustical sensors that were highly sensitive to bird songs and deemphasized low-frequency noise from military training activity. The balloon control system included GPS track logging, altitude control, and bidirectional wireless communications.
