Oahu Oo

The O‘ahu ‘ō‘ō was first mentioned by Andrew Bloxam. While in the Hawaiian Islands in 1825 as the naturalist on board HMS Blonde, he saw live birds which were brought to him by locals. He preserved one specimen obtained in this way. He wrote in his diary (not published until much later): "They are now very scarce in all the islands. I did not see even one in the different excursions I made, & the natives asked a high price for the very few they brought to me." Bloxam misidentified his birds as the species now called Moho nobilis. John Gould scientifically named and described the O‘ahu ‘ō‘ō in 1860, when it was already regarded as vanished for 23 years. The last reliable evidence was a collection of about three birds by German naturalist Ferdinand Deppe in 1837. He found these specimens in the hills behind the capital, Honolulu. After surveys, led by ornithologist Robert C. L. Perkins and others, failed to find the bird between 1880 and 1890, it was described as almost extinct. Today there are seven specimens in museum collections in Berlin, London, New York City and Cambridge (Massachusetts). The reasons for its extinction were probably avian diseases caused by introduced mosquitos, habitat destruction by cattle and goats, deforestation, predation by introduced rats, and hunting (their plumage was used in robes for the Hawaiian nobility).
