Hawaii Island locations of reintroduced Alala from automated radio telemetry tracking system, 2017 cohort
March 12, 2021
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.

Automated telemetry reveals post-reintroduction exploratory behavior and movement patterns of an endangered corvid, ʻAlalā (Corvus hawaiiensis) in Hawaiʻi, USA
Continuous movement monitoring is a powerful tool for evaluating reintroduction techniques and assessing how well reintroduced animals are adjusting to the wild. However, to date, continuous monitoring has only occurred for large-bodied species capable of carrying heavy tracking devices. In this study we used an automated VHF radio telemetry array to investigate the exploratory behavior...
