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

USGS Science Data Catalog (SDC), economy, none, Fewer tags Lower Puna, Hawai`i Island, bird and habitat surveys of 2003 and 2016 The newly identified rapid ‘ohi‘a death (ROD; Metrosideros polymorpha) originated in the lower Puna district and its distribution has spread across Hawai‘i Island. As ROD expands it is expected that the loss of the dominant tree species will adversely affect bird populations. This project is a first attempt to describe the relationship between the impacts of ROD on the Hawaiian avifauna, especially the native Hawai‘i ‘amakihi (Hemignathus virens virens) an omnivore found in a wide range of native and nonnative habitat types. ‘Amakihi was generally rare below about 1,300 m elevation (Scott et al. 1986, Reynolds et al. 2003) but recent surveys found that the species is resident and breeding in native-dominated ‘ohi‘a...

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.
