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