      Once common and widespread throughout the western United States and Canada, the western burrowing owl (Athene cunicularia hypugaea) population has declined to the point where the species is now designated as a Species of Special Concern in California. Their presence in development areas, including renewable energy facilities, necessitates an effective strategy for protecting them. This study is the first of its kind to test both passive and active relocation techniques with burrowing owls and evaluate their relative effectiveness with and without the addition of conspecific cues (such as acoustic playback of owl calls and imitation whitewash to attract the owls)....
