This data release includes data and metadata containing estimated and predicted locations of radio telemetered Hawaiian forest birds. Radio telemetry data was collected using an automated radio telemetry network from 2014 to 2019 from birds in two study sites, one a continuous forest and the other a fragmented forest. Four bird species that varied in age and sex were studied: the nectarivorous ʻiʻiwi (Drepanis coccinea) and ʻapapane (Himatione sanguinea), the frugivorous ʻōmaʻo (Myadestes obscurus), and the generalist Hawaiʻi ʻamakihi (Chlorodrepani virens). Data were used in the analysis for the manuscript entitled "Landscape fragmentation alters movement behavior and space use of Hawaiian forest birds."

We used an automated radio telemetry network to document the activity of radio telemetered Hawaiian forest birds in two study sites, one a continuous forest and the other a fragmented forest. Four bird species were studied: the nectarivorous ʻiʻiwi (Drepanis coccinea) and ʻapapane (Himatione sanguinea), the frugivorous ʻōmaʻo (Myadestes obscurus), and the generalist Hawaiʻi ʻamakihi (Chlorodrepani virens; hereafter ʻamakihi). In the continuous forest we also tracked two non-native species: the frugivorous red-billed leiothrix (Leiothrix lutea), and the generalist warbling white-eye (Zosterops japonicus). Using sequential changes in radio signal strength we were able to estimate when birds were moving or resting. This data release consists of one tabular dataset with 2,026,289 records that contains the bird information, designated activity characterization, telemetry network information, and signal strength.

This data release contains the point-transect distance sampling records of forest bird survey collected in the Kohala Mountain complex in 2017, including survey point IDs, distance to detected birds, sampling conditions, ohia phenology, habitat classifications and background noise levels. This data release consists of one tabular dataset.

This data release includes data and metadata containing estimated and predicted locations of radio telemetered Hawaiian waterbirds. Radio telemetry data was collected using an automated radio telemetry network from March 2016 to August 2018 on O'ahu, Hawaii, for three species: ʻAlae ʻula (Hawaiian Gallinule; Gallinula galeata sandvicensis), ʻAlae keʻokeʻo (Hawaiian Coot; Fulica alai), and Aeʻo (Hawaiian Stilt; Himantopus mexicanus knudseni). Data were used in the analysis for the manuscript entitled " Hawaiian waterbird movement across a developed landscape."

The data are in the comma delimited file HAVO_2015_2016_BirdSurveyData.csv. Hawaiʻi Volcanoes National Park (HAVO) was surveyed for landbirds and landbird habitat from February through April 2015 and February through April 2016. This information provides the second datum in the time-series of Pacific Island Network (PACN) monitoring for long-term trends in landbird distribution, density, and abundance. Initial PACN surveys were conducted in 2010 and are repeated every five years. The entire survey area was comprised of eight tracts in forest, woodland, and shrub habitat, totaling 26,364 ha. Each tract was surveyed using point-transect distance sampling to calculate estimates of bird abundance and density. In addition to the permanent PACN survey transects, randomly generated point-transects were also surveyed, allowing for a split panel sampling design. A total of 14,061 bird detections of twenty-eight species were recorded during point counts; 8 species were native to Hawaiʻi and 20 species were non-native.

We used an automated radio telemetry network to track the movement of two nectivorous Hawaiian honeycreepers, the ʻapapane (Himatione sanguinea) and ʻiʻiwi (Drepanis coccinea), collecting high temporal and spatial resolution data across the annual cycle. We identify movement syndromes using a multivariate analysis of multiple movement metrics and assessed seasonal changes in movement behavior. Birds made long-distance flights, including multi-day forays outside the tracking array, but exhibited a high degree of fidelity to a core use area, even in the non-breeding period. Both species visited forests at elevations where avian malaria potentially occurs, although overall exhibited very little seasonal change in elevation (< 150 m) and regularly returned to high-elevation roost sites at night. Birds were tracked from January 2014 to July 2016.
