Monitoring bird and bat species using audio devices
Abstract
Monitoring of bird and bat species throughout long time periods can be highly time-consuming and costly. Next to travel expenses to reach the study sites, personnel costs can sum up to high expenses. To overcome these issues, bioacoustic monitoring can be used in place of field surveys, but acoustic recording units usually have also high initial investment costs. During the last decades, increasing technical progress constantly led to new products and nowadays low-cost devices are offered. However, highly specialized microphones with a sophisticated circuitry are necessary, raising the question, if microphones of low-cost products are capable of monitoring bird and bat species at a professional-level. Within the project, usability, sensitivity and accuracy of two bioacoustic records will be assessed and compared. In addition, we will study if data collected with bioacoustic recorders are comparable with data collected during field observations.
