夏威夷烏鴉於2002年已野外滅絕,保育團體過去努力於圈內繁殖,並於最近把5隻野放回牠們的棲息地,雖然當天情況良好,但不久其中3隻被發現突然死亡,保育團體立刻把另外兩隻烏鴉收回,希望先了解問題再嘗試。

hawaiian crows went extinct in the wild in 2002. conservationists tried to captive-bred them and was happy to release 5 of them in the wild recently. the birds had been observed doing well at the beginning, but 3 of them were found dead soon after! the conservationists recaptured the other two birds to ensure their safety.
