(Salomonsen in Peters 1967, XII, 424). The Hawaii Oo (or ‘Ō‘ō  in Hawaiian orthography) was last seen in 1934. Recent work indicates that these birds were allied to the silky-flycatchers Ptiliogonatidae and waxwings Bombycillidae.

● “The yellow tufts of costal feathers on this beautiful bird, furnished the material for the splendid and costly royal robes, capes, and “lei’s,” or head-dresses of the Hawaiians in former days. The bunches of feathers called hulu... are still prepared and received in payment of a poll tax to the King; they are afterwards made up principally in “lei’s”, or head-bands worn by the ladies, and are beautiful but costly ornaments; but few can afford to wear them. The mantles made of these feathers, were, until lately, considered the principal treasures of the crown; now they are not to be seen; the labour of collecting the feathers and attaching them to a network base – a labour of years – being too great” (Peale 1848) (‡Moho).
● “Its large size and the great development of the feathers of its crown and beard render it a remarkable bird to look at; and the admirable way in which the original skins were prepared justify the large price of twenty pounds which I had to pay for my first specimen” (Gould 1880-1887) (Oreonympha).
