Summary
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 [...]

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.

The purpose of data collection was to document movement of two native nectarivorous birds at Hakalau Forest National Wildlife Refuge across several years to better understand area use and seasonal movement patterns.
