Automated Acoustic Bat ID Software Programs

Approved Programs

One or more of the specified versions (and settings if specified below) of the programs identified below are approved by the USFWS for use for presence /probable absence (P/A) surveys for Indiana bats (Myotis sodalis; MYSO).  Similarly, the approved programs may also be used for P/A surveys for northern long-eared bats (Myotis septentrionalis; MYSE). These zero-crossing programs below have been independently tested by USGS researchers and passed the Service’s standardized test/validation process (see USGS reports below and USFWS/USGS software testing protocols). Unless directed otherwise on this webpage, use each developer’s recommended settings for MYSO/MYSE P/A surveys. As outlined in the survey guidelines, survey work plans submitted to USFWS Field Offices must specify which software program(s) will be used prior to conducting P/A surveys. While not required, manual vetting (i.e., qualitative analysis) of probabilistic MYSO and MYSE calls identified in software outputs is highly recommended (see Appendix C of the current summer survey guidelines).

1 In some specific cases, KPro users may be able to use a more recent/current classifier than the one used when originally tested and approved for use. USGS and FWS have been informally testing some of these combinations in coordination with Wildlife Acoustics. Unless otherwise indicated within this table, we recommend surveyors continue to use the tested and previously approved combinations of software versions and classifiers to ensure FWS approval of auto ID results. This table will be updated as new test results become available.

 

2 When provided as an option, users are to select the most appropriate species assemblage/geographic region, which includes MYSO and/or MYSE and all other species that may reasonably occur in a given survey area/region.

Bat surveyors should bookmark this site and regularly check it to ensure that they are using an approved version(s) of each program. Newer software versions containing changes to their classifiers will require additional testing by USGS before they are approved for use in P/A surveys. Unless otherwise indicated in the table above, surveyors should use the most current approved software version/classifier combination available and use manufacturer's recommended settings for Indiana bat P/A surveys.

 

BCID Program (Ryan Allen, Bat Call Identification, Inc.)

According to www.batcallid.com, “BCID East is a powerful application that allows users to automate the identification process of bats in the Midwest and North Eastern United States.” This program is currently available for purchase from the batcallid website listed above. Questions regarding this program should be directed to Mr. Allen at mrallens@batcallid.com.

 

EchoClass (Eric Britzke, ERDC)

The Service funded Dr. Eric Britzke with the U.S. Army Engineer Research and Development Center in Vicksburg, Mississippi to develop an automated acoustic bat identification software program suitable throughout the range of the Indiana bat. Version 3.1 is publicly available for use (free of charge) and may be downloaded from the links below.

Echoclass v.3.1 32 bit zip file (2MB)

Kaleidoscope Pro (Wildlife Acoustics, Inc.) (zero-crossing)

According to Wildlife Acoustics, “Kaleidoscope Pro sets new standards for bat auto ID software and is one of fastest, easiest-to-use, and most flexible bat auto ID applications available.”  It is capable of working from full-spectrum, zero-crossing, or time expansion recordings. Kaleidoscope is available for both a free two-week trial period and/or purchase. Visit the WA website at  http://www.wildlifeacoustics.com/products/kaleidoscope-software

 

Candidate Programs (full-spectrum)

The full-spectrum candidate programs below have not yet been tested by USGS and therefore are not yet approved by USFWS for stand-alone use for MYSO and/or MYSE P/A surveys. In the interim, one or more of the candidate programs below may be used in conjunction with one or more of the “approved” programs for MYSO/MYSE P/A surveys.

 

NOTE: Despite repeated requests for voluntary assistance from numerous acoustic experts within the bat community, the USFWS and USGS have not yet been able to develop a robust, full-spectrum test call library that doesn’t contain all or a significant proportion of the same known call files as those used to develop and train the candidate programs themselves. The appropriateness and feasibility of alternative testing strategies are being explored, but will require additional time and coordination and ultimately the blessing of managers in all affected USFWS regions (i.e., R2, R3, R4, R5 and R6). Thank you for your patience and understanding as we seek to resolve this issue.

 

BCID (Ryan Allen, Bat Call Identification, Inc.)

As noted above, USGS has not yet been able to conduct a standardized test of software programs that can analyze full-spectrum data.  Therefore, BCID is not approved for stand-alone analysis of full-spectrum data at this time.

 

Kaleidoscope® Pro (Wildlife Acoustics, Inc.)

As noted above, USGS has not yet been able to conduct a standardized test of software programs that can analyze full-spectrum data.  Therefore, Kaleidoscope is not approved for stand-alone analysis of full-spectrum data at this time.

 

SonoBat™ (Joe Szewczak)

Sonobat (http://www.sonobat.com/) software “provides a comprehensive tool for analyzing and comparing high-resolution full-spectrum Sonograms of Bat echolocation calls recorded from time-expansion bat detectors. With its intuitive and direct interface, SonoBat makes it easy to record, process, display, and analyze calls with great sophistication.”  Dr. Joe Szewczak submitted version 3.2.2 to the USGS for standardized testing in March 2015.  Unfortunately, the full-spectrum testing issue noted above has not yet been resolved.

 

As noted above, USGS has not yet been able to conduct a standardized test of software programs that can analyze full-spectrum data.  Therefore, Sonobat is not approved for stand-alone analysis of full-spectrum data at this time.

 

UPDATE: FWS biologists met with Dr. Szewczak and his associates in March 2017 during the 2nd Symposium on Bat Echolocation Research in Tucson. A path forward was set, but we are still awaiting receipt of a sufficient number of FS calls of known ID so USGS can develop a FS test that is on par with the current ZC test for MYSO and MYSE.

 

Software Developers

Software developers wishing to have their program/new versions evaluated by the Service should complete the submittal form below and send it to Andrew King (andrew_king@fws.gov) in the Indiana ES Field Office.

How to Contribute Additional Call Files to the Master Test Library

In the interest of improving the overall number and diversity of call files included in the Master Test Library, the Service encourages qualified individuals to voluntarily contribute additional call files (full-spectrum and zero-crossing) of known species. Call files will be considered for inclusion if species identity is unequivocally known. Example methods of generating unequivocal identifications include recordings of hand release and/or light tagged bats. Passively collected and manually identified calls may be considered on a case-by-case basis pending discussion with the Service, but in general are not a preferred source of calls to be used in testing. Files used by developers to train software programs should not be submitted for inclusion in the Master Test Library. To permit future development of software testing (e.g. regional test libraries), contributors are requested to included relevant metadata along with their file submissions using the call submittal form below. 

 

If you are interested in contributing known call files to the Master Test Library, please contact
Mike Armstrong (Mike_Armstrong@fws.gov), Robyn Niver (Robyn_Niver@fws.gov), or Andy King (Andrew_King@fws.gov).
