This large, black, and extraordinarily loud bird vanished from Hawaiian forests in 2002. Fortunately it survived in aviaries, and captive bred birds began to be released back into the wild in 2016 in remote parts of the Big Island; early signs are promising with several pairs attempting to nest. Known to Native Hawaiians as ʻAlalā, it is the only crow or crow-like bird currently found on the archipelago. It is much bigger than the crows found on the US mainland, and is closer in size to a raven. Gives a variety of loud caws, croaks, and squeals.
