Summary
Alala, or Hawaiian Crow (Corvus hawaiiensis), were extinct in the wild since the early 2000s. The first effort to reintroduce captive bred Alala back into the wild was conducted at Puu Makaala Natural Area Reserve on Hawaii Island. The 2017 release cohort were released in two stages and were the only Alala in the wild. Using automated radio telemetry tracking towers (n=4) that were distributed around the release area, we tracked the birds from September 26, 2017, to May 19, 2018, to document early exploratory movement of these birds in the wild.

The purpose of data collection was to document movement in the first year of the 2017 reintroduction cohort, who were the only Alala in the wild at the time. The data provides important information on how Alala explore their environment and release landscape.
