At the time of discovery by Europeans, it was still relatively common on the Big Island, but that was soon to change. The Hawaiʻi ʻōʻō feathers were carefully plucked as they only removed a few a time and then the bird was released by Native Hawaiians. Its striking plumage was used for ʻaʻahu aliʻi (robes), ʻahu ʻula(capes), and Kāhili (feathered staffs) of aliʻi (Hawaiian nobility). The Europeans too saw the striking beauty of this bird and hunted many of them for specimens in personal collections. Some were even caught and put in cages to be sold as song birds only to live for a few days or weeks before diseases from mosquitoes befell them. The decline of this bird was hastened by both natives and Europeans by the introduction of the musket which allowed hunter and collectors to shoot birds down from far away places, from great heights, and in great numbers. As late as 1898, hunters were still able to kill over a thousand of the birds, but after that year the ʻōʻō population declined rapidly. The birds became too rare to be shot in any great quantities, but continued to be found for nearly 30 years. The last known sighting was in 1934 on the slopes of Mauna Loa.
