This site was established by the Wyoming Natural Diversity Database in cooperation with the Wyoming Bat Working Group to facilitate the identification of bat calls by interested parties in the Wyoming conservation community. It is intended to be a central distribution site for the exchange of credible reference calls recorded in Wyoming.
We only post calls emitted from positively identified bat species, usually recorded by experienced bat biologists and technicians. All calls were recorded in the field from free-flying or recently hand-released bats. Most calls posted here were recorded using ANABAT hardware and software. You must have the ANABAT or ANALOOK software to display these files. In order for the program to recognize them as bat calls, they must have a file extension ending in a pound sign (e.g., 6829763.00#).
Currently, the Wyoming Game and Fish Department, Non-game Program and the Wyoming Natural Diversity Database have contributed calls to this library. Please consider adding your name to the list by contributing calls of your own. Contact Doug Keinath to do so.
