Species Information 

The Mohoidae family colonized Hawaiʻi 14-17 million years ago. These Hawaiian honeyeaters pollinated the lobeliad plants that have existed in Hawaiʻi for 13 million years (Fleisher and McIntosh 2001, Fleischer et al. 2008, Banko and Banko 2009). Very little is known about this historic species, beyond the Native Hawaiian’s use of their yellow feathers in featherwork (Lepson 1998).

Distribution  

Oʻahu. Specimens were collected around Honolulu in the Koʻolau Mountains, but Olson and James (1982b, in Pyle & Pyle 2017) also found subfossil evidence of the Moho genus at Barber’s Point. 

Threats 

The exact threat that lead to Oʻahu ʻōʻoʻs extinction is uncertain. However, the species was likely susceptible to the same factors that threaten other native Hawaiian forest birds, including loss and degradation of habitat, predation by introduced mammals, and disease.
