Sparse detections for eight species precluded modeling detection and occupancy probabilities. Call traits included characteristic call frequency (Fc), call bandwidth (BW), and call duration (Dur) and were obtained from summaries of western United States bat call characteristics included in Sonobat (SonoBat 4.2.2, SonoBat, Arcata, CA, US). We used body mass from the PanTHERIA database (Jones et al., 2009) except where indicated and foraging strategy was taken from multiple sources.
