[Abstract]

Very interesting. I think the 'I'iwi is still one of the least understand honeycreepers. At the beginning of the 20th century it was regarded as close relative of the Mamos (Drepanis) and now it seems that it is closer to Himatione.
 
TiF Update July 11

The genera Palmeria, Himatione, and Vestiaria have been merged into Drepanis. The genetic distance between them seems to be small (Lerner et al., 2011) and there is evidence of hybridization between Vestiaria and Himatione (Knowlton et al., 2014). Although I think the genera I use for the Hawaiian Honeycreepers are oversplit, I consider the AOU genera even more oversplit. I haven't gone further on the lumping because data on the extinct species is too limited.

I follow the recent AOU decisions (56th supplement) to split the Apapane, Akepa, Greater Akialoa, and Nukupuu.

Abstract

Hawaiian honeycreepers, comprising an endemic radiation of passerine birds in the Hawaiian archipelago, have suffered losses of individual island populations and the extinction of many species as a result of colonization of the islands by Polynesians and, more recently, introduced avian pox virus and avian malaria. Here, I test the idea that populations have an intrinsic tendency toward extinction regardless of the cause. The distribution of each species before the arrival of humans in the archipelago was inferred from present distribution, historical records, and fossil remains. On the basis of these records, each species was placed in one of four stages of the taxon cycle: (1) expanding or recently expanded, (2) differentiating, (3) fragmenting, or (4) single-island endemic. Subsequent extinction of individual island populations was most frequent in stage 3 species, which had already suffered loss of individual island populations, suggesting commonality in vulnerability to extinction from anthropogenic and nonanthropogenic causes.
