From the German Naturalis website: "The cultivation of the Hawaiian Islands had a disastrous effect on the indigenous avifauna. After Europeans arrived in the archipelago, various rails, thrushes, and many of the famous Hawaiian honeycreepers vanished. Another group which suffered heavily were the O-o honeyeaters. All four species of Moho are extinct. These are the Hawaii O-o Moho nobilis, the Molokai O-o Moho bishopi, the Oahu O-o Moho apicalis and the Kauai O-o, Moho braccatus."
I have included four of Frohawks paintings of the O'o to show the females/juveniles, as well as four O'o species. It is interesting to note that the Latin names used by Frohawk differ markedly from those in my more modern book. This last one has the same subspecies name as Marian usually paints: "nobilis."
Marian Berger's paintings of O'o can be found on my website at: 1985 Lithographs, 2010 Giclees, Odds and Ends, Other Bird Prints, and the Marion Collection.
