Occupancy data were collected during the 2010 surveys of Alamagan, Commonwealth of the Northern Mariana Islands (CNMI). Data were collected at points along transects where trained observers listened for Reed-warblers during the 3-minute survey period (30 seconds of playback followed by 2 minutes and 30 seconds of observation). Observers recorded the horizontal distances of any Reed-warblers heard/and or seen, direction of the bird from the observer, and time of detection. The data set also includes covariates that may influence the occupancy of birds.

Point transect distance sampling data collected during the 2010 surveys of Alamagan, Commonwealth of the Northern Mariana Islands (CNMI). Data were collected at points along transects where trained observers recorded the detection type (heard, seen, or heard then seen) and horizontal distance (exact distance in m) from the station center point to individual birds detected during an 8-min count. To increase the numbers of detections, survey data from 40 detections from the CNMI Division of Fish and Wildlife (DFW; 2000) surveys of Alamagan, and 46 detections from Saipan surveys described in Camp et al. (2009). The count length of the DFW surveys was only 5 minutes; therefore, we included detections from the first...
