Alamagan, Commonwealth of the Northern Mariana Islands, Nightingale Reed-warbler point transect survey data, 2010

Metadata Updated: October 28, 2023

Point transect distance sampling 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 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) were added to this dataset. The count length of the DFW surveys was only 5 minutes; therefore, we included detections from the first 5 minutes of the 2010 survey. The data set also includes covariates that may influence the detectability of birds. Camp, R. J., Pratt, T. K., Marshall, A. P., Amidon, F. and Williams, L.
