ABSTRACT- In the last 5 years, uses of the Anabat echolocation system to detect, archive, and analyze calls emitted by bats has increased dramatically. Recent advances have allowed for the rapid and constant accumulation of bat call files. Here we describe a system of filters and storage media for the rapid and accurate analysis of call files. A call sequence for a selected bat can be examined for species-specific characteristics such as slope, duration, and frequency. These then can result in measurements that can be used to form a species-specific filter. Filters can be constructed based on captured, then hand-released bats so that species-specific values are used to construct a filter. Those filtered files can then represent a particular species or sonic group depending on the goals of the investigation. In order to handle large quantities of call data, filters increase the speed and accuracy of call sorting and organization. They are also extremely plastic and can allow filtering for a variety of purposes. Once organized, call files are available on the web stored in an acoustic library. The bat call library is archived and available to any qualified researcher following the model of natural history museum collection data.
