How it Works

flying bats.
Bats leaving their roost site.
ReBAT uses full-spectrum ultrasonic detectors to collect data on the entire soundscape, which collects more information than zero-crossing detectors and allows accurate identification to species or species group. (Learn why species identification is important)

After ReBAT collects acoustic data, it processes and stores the data onsite and then uses a cell signal to send the data to our Operations Center. Data can also be accessed remotely, and system health can be monitored remotely.

The bat call data are processed using software approved by the U.S. Fish and Wildlife Service, manual expert analysis, or a combination of both. Once the acoustic call files have been identified to species or species group, the data is examined for spatial and temporal variations in bat activity and correlation of bat activity with weather patterns. The results are provided in detailed monthly and annual reports. ReBAT services are also available without data analysis and reporting (see Service Levels).

With a robust solar power system or connection to the mains power at the turbine, each ReBAT system can run indefinitely. For example, it can perform for the typical duration of preconstruction monitoring at a wind energy facility, which ranges from 7 months to more than 18 months depending on regulatory requirements.

ReBAT is also used with the TIMRSM system and services to reduce bat fatalities at operating wind facilities. (Learn more about TIMR)

ReBAT versus Other Bat Detectors

Normandeau developed the ReBAT system and services to increase the effectiveness of bat acoustic monitoring and to overcome the limitations of other acoustic detection systems. The most commonly used bat detectors are frequency division detectors (including zero-crossing detectors) and full-spectrum detectors, such as ReBAT.

A bat detector should be selected based on its ability to meet study requirements. This table illustrates the differences between other bat detectors and ReBAT.
