Point transect distance sampling data collected during the 2003 to 2016 surveys of lower Puna District, Hawai`i. Data were collected at points along rural highways, secondary roads and residential streets 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. The data set also includes covariates that may influence the detectability of birds.
