  • Common Name: Oʻahu ʻakialoa 
  • Scientific: Akialoa ellisiana 


No available recordings.

Conservation Status 

Extinct. Last confirmed sighting in 1892, though there are subsequent unconfirmed sightings described in Pyle & Pyle 2017.

Species Information 

The Oʻahu ʻakialoa is thought to have been more similar to the lesser ʻakialoa than those species found on Maui and Kauai (Olson 1995). Their long beak enabled them to eat bugs and the nectar of native flowers such as those from ʻōhiʻa trees. They were similar to ‘amakihi, but with larger bills.


O’ahu. Specimens were collected in Nuʻuanu Valley.


This honeycreeper could be found in high elevation forests. 


Oʻahu ‘akialoa likely were susceptible to the same factors that threaten other native Hawaiian forest birds, including loss and degradation of habitat, predation by introduced mammals, and disease.
