Manual Vetting and Second Opinions
MANUAL VETTING
& SECOND OPINIONS
Analyzing bat echolocation recordings is difficult. Many species have varying degrees of overlap in their echolocation calls. Additionally, high-frequency sound used by bats is uniquely affected by atmospheric conditions, temperature, humidity, and mechanical effects, further reducing abilities of computer-assisted algorithms to return accurate results. The Bat Survey Solutions staff has decades of experience recording, viewing, measuring, interpreting, and analyzing North American bat calls with insights from the physical properties of high-frequency sounds. Therefore we are uniquely positioned to provide critical expert manual vetting services to confirm or reject computer-assisted classifications, and bring higher degrees of accuracy to acoustic surveys and their implications for bat management.
Our staff has been intimately involved in reviewing and revising many North American acoustic survey guidelines as they have been developed and brought on-line. We can provide critical commentary and review services for a full range of active, passive, and mobile acoustic surveys, including analysis of extremely large data-sets and interpretation of all major classification software outputs.
