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....

A major advancement in the use of radio telemetry has been the development of automated radio tracking systems (ARTS) which allow animal movements to be tracked continuously. A new ARTS approach is the use of a network of simple radio receivers (nodes) that collect radio signal strength (RSS) values from animal-borne radio transmitters. However, the use of RSS-based localization methods in wildlife tracking research is new and analytical approaches critical for determining high quality location data have lagged behind technological developments. This data release contains data used to test the application of analytical filters (signal strength, distance among nodes) to data from real and simulated node networks...
