Summary

Description

Aural surveys using tape recorded calls proved to be an efficient and effective way to survey large expanses of shallow marsh for black rails Laterallus jamaicensis. Approximately 28 to 31 rails were detected at 15 different sites in Florida in the spring and summer of 1989. We recommend further extensive surveys to determine current status and distribution of this elusive bird. If such surveys suggest an uncertain future for black rails and more detailed monitoring is deemed necessary, then detailed research will be needed to refine the call count method.
